Trollhättan Canal

On Saturday, June 27, after hustling to get off the dock in Gothenburg and under the Hisingsbron, we started up the Göta älv, the river which is most of the Trollhättan Canal. Near its east end, the canal bypasses the once mighty Trollhättan Waterfalls. Opened in 1800, it is 82 kilometers long, with only 10 kilometers of its length being manmade. It was designed to connect Göthenburg on the west coast of Sweden with the industries of Lake Vänern and has six locks. Built for cargo traffic, which it still handles, it is now mainly used by pleasure craft (although the bigger boats have the right of way). The original 1800 locks were extended in 1844 after the Göta Canal, which could handle larger ships, was completed. In 1916, the current system was inaugurated by King Gustav V and features 4 massive locks at Trollhättan capable of handling ships up to 89 meters long.

Reeds, grasses and sometimes water lilies border the river on either side. We passed fortresses, castles, cultivated fields, forests and villages. Occasionally swans would swim by. At 49 kilometers from Gothenburg, at Lilla Edet, we passed through the first lock, rising 6 meters. Following the advise of the lock keeper, who indicated there was too much traffic coming downstream, we stopped for the day at 3:30 p.m., having only motored upriver for 4 hours for 54 km. We were actually tired, because it was a really hot day, with the high temperature at 84°F (29°C)! I was wearing my swimsuit for the first time this summer. 

We walked into the town of Lilla Edet, but it was pretty quiet, so we relaxed on the boat for the rest of the day and chatted with people on other boats. The Scandinavians and most Germans speak fluid English, often with no accent, putting most of monolingual English speakers to shame.

On Sunday, June 28, we cast off the dock and headed for Lake Vänern, with 5 more locks to go. Around 1 p.m., after a flight of 4 locks, we tied up temporarily at Trollhättan with all the other boats because the next bridge was not operational but was being worked on. There was no estimate of the amount of time it would take. We went on land to explore.

First we went to the little canal museum, housed in a 1893 warehouse. In addition to over 50 small boat models, there are exhibits on the history of the building of the canal as well as dioramas that show where the three different lock systems were constructed. We also watched a short film which provided more information.

The 1800 locks

Afterwards, we walked upstream, crossed to the east side of the river, passed a Saab museum which was not open, and made it to the center of town where there is a large, attractive plaza. Despite the nice weather, few people were out in the city. We were getting hungry and walked to the waterfront to find a place for lunch. We enjoyed a good meal outside sitting right by the water. The inoperable bridge was just around the bend. As we enjoyed our food, boats which were waiting on the opposite side of the river began to move, indicating the bridge had been fixed in a reasonable amount of time. Then boats that had passed through the 4 flights of locks before or after us going upstream motored past.

There are many trails in the Trollhättan area, and we decided to wander along some of them. This allowed us to see the bed of the waterfalls. The water is now diverted through a power plant and the locks, but once a year, during a 3-day festival in July (Waterfall Days), the floodgates open six times each day, releasing over 300,000 liters of water per second.

Knowing it was too late to continue that day, after the falls, Peter and I split up; he wanted to hike up and I wanted to hike down to see the church. (Occasionally, we just need time away from each other.) The 1862 red-brick, Neo-Gothic style church with its 40 meter tower is on an island in the river. Its parishioners used to live close by, but the center of the city shifted to the east bank around the turn of the 20th century. The interior is light-filled and peaceful (and cool).

It was hot and I would have loved a Coke Zero (since there are no Diet Cokes here), but only Pepsi products were sold locally, so I treated myself to a salted caramel ice cream with toffee crunch, which I relished in the pilot house. After that, I took a shower and felt much better. 

Peter returned from his up and down hiking with an ice cream in hand also! We relaxed on the boat, had dinner and took another walk as the sun was getting low in the sky. We walked along some parts of the obsolete locks, partly opened and supporting lush vegetation on their edges. We also admired some typical Swedish architectureIt was a lovely evening.

The next morning (Monday, June 29), we were off for Lake Vänern around 9:30. After waiting almost an hour for a railway bridge to open and another 50 minutes for the last lock, we entered it. There were a lot of boats waiting to get in, and the lock was quite large. I was annoyed that we got pushed to the rougher port side even though we were near the front of the line and other boats did not wait their turns in exiting, while Peter patiently let them pass. My frustration dissipated as we left the confines of the canal and emerged on the lake. We were delighted to be able to unfurl the sails and sail on open water either on a deep broad reach or wing-and-wing in 20 knots of wind. Just after 8 p.m., we anchored by ourselves (Other boats went to the marina on the other side of a peninsula.) right beside the magnificent castle, Läckö Slott.

Touring that was for the next day.

More about Skagen; Valön island, Öckerö island and Gothenburg, Sweden

On Monday, June 22, our first stop was the Swedish church in Skagen, built in 1925. In the first half of the 20th century, Skagen Harbor was widely used by Swedish fishermen, and the church was built so that the fishermen could have a place to stay when they were away from their homeland. It also was intended to deter them from mischief.

We rented bikes at the Skagen Harbour Hotel and received a lot of helpful information, maps and guides from the receptionist. We out of town and cycled north. On the way, we passed the conical stack of dead trees and branches for the bonfire later that evening. On top, human-sized, was an effigy of a witch with a red cloak, representing evil. We arrived at the Grey Lighthouse, built in 1858 to replace the White Lighthouse (1747) in Skagen, which is 1.6 kilometers southwest of the new one, due to the ever-growing length of the peninsula.

Peddling onward, we passed the ruins of German bunkers from WWII, part of the Atlantic Wall, an extensive system of coastal fortifications built by Nazi Germany between 1942 and 1944 along the coast of continental Europe and Scandinavia, from the Spanish border up to Norway, as a defense against an anticipated Allied invasion of Nazi-occupied Europe. The defensive wall was never fully completed, but about 15,000 steel-reinforced concrete structures were constructed, including machine gun emplacements, anti-tank casemates, heavy artillery fire control posts, munitions stores, observation posts, troop shelters and communications bunkers. Although some were destroyed after the war, many are still visible as derelict structures all along the coast, and we have encountered many. In Skagen, there is a Bunker Museum, but we did not take the time to visit since it was so nice outside.

We parked out bikes at the end of the road and joined a few hundred other tourists walking along the beach on the east side of the peninsula, encountering beached jellies in many colors and a European viper, squiggling through the sand. The peninsula narrows to a sharp point where the more calm Kattegat Sea (part of the Baltic) meets the Skagerrak Sea (part of the North Sea). A swirl of waves extends out from the end of the land at Gremen. Many people waded out along the line of two bodies of water connecting. We continued on, walking along the Skagerrak, where there were many fewer people and eventually returned across the vegetated dunes to the Kattegat, where we took to our bikes again.

Gremen is the tip of Denmark, but it is not the northernmost point. That is Nordstrand. We cycled there and set on a large piece of weathered-to-white driftwood for a snack while listening to the little waves dissipating on the shore.

Nordstrand 

Near Nordstrand is Skagen Odde Naturecenter. We arrived about 45 minutes before it closed but had enough time to watch the film and see some of the exhibits, which include not just natural history but local Scandinavian architecture and design. 

As we cycled and walked throughout the day, we were often surrounded by bird song and occasionally saw the animals producing the melodies and calls. Most of them hid among the grasses and brush. At Gremen, we were lucky to have close encounter with a species in bunting family, the yellowhammer, a lovely yellow and brown bird; it was a new lifer for us!

Yellowhammer

We spent a couple hours resting on the boat and then walked along the wharf and past the yellow houses to reach Vippefyret, the bascule light originally constructed in 1627 as a navigational aid, serving until 1747 when the White Lighthouse was put into operation. (The current structure is a copy on the original site.) It was Denmark's first bascule light with an open fire basket. The basket was lowered to ground level and filled with combustible material which is then ignited. When the light was raised again, it could be seen for 26 kilometers (14 nautical miles). No longer in use for navigation, it is lighted and raised once a year as part of the local midsummer festivities on St. John's Eve. These festivities were the main reason we chose to visit Skagen.

Vippefyret and people out for St. John's Eve festivities

Vippefyret was already lit when we arrived shortly after 8 p.m. There was a program of events including speeches and songs that was scheduled to begin then. About 20 minutes later, from a stage near the Vippefyret dune, a woman with a sweet voice began to sing melodic and peaceful tunes, which we could hear from the spot we chose on the dune in front of the bonfire site, looking out to sea. There were poems and speeches and more songs, almost like traditional hymns in style. People continued to gather until there was a couple thousand. I was surprised that there was no line in the sand or any kind of indication of how far away from the dry wood and the witch the people should be; everyone seemed to keep a safe distance without instruction or enforcement. People were mingling and chatting but not partying. It was a low-key event. Five firefights in gear arrived about 9:15 but it was another 20 minutes before the pile was ignited. There was no roar from the crowd, no "Oooh's" or "Aaah's" No one was inebriated; few people were even drinking. We were quite surprised; we had anticipated rowdy partying. However, we liked the quiet ambience of a community coming together to watch evil dispelled with the smoke as the witch's clothes, and then her cross structure and and finally all of her burned away.

People waiting patiently on the beach. Can you spot Peter?

The next day, Wednesday, June 24, it was good-bye to Denmark and hello to Sweden. We were getting ready for departure when John and his 13 young students came by. It was the last week of school, and they were on an outing and had come to see his boat. They all came aboard for a short time, and we cast off the dock at noon.

With wind at 7-10 knots, we tried and failed to sail northeast, but the engine carried us to the island of Valön, part of the Bohuslän archipelago, a stunning group of about 8,000 islands and skerries stretching along Sweden's picturesque west coast from Gothenburg to the Norwegian border. It would have been wonderful to spend some time exploring this area, but the Schengen Agreement limits us to 90 days in continental Europe. We dropped anchor for the night around 6 p.m., enjoyed the tranquility, watched the sunset at 10:30, and went to bed, enjoying the subtle swaying of the boat at anchor.

The next morning (Thursday, June 25), we weighed anchor at 10:40 and sailed south among the numerous little islands for three hours; the channel narrowed and was criss-crossed with yellow ferries, and we furled the sails and turned on the engine. We arrived on the island of Öckerö at 2 p.m. Waiting to catch our lines on the municipal dock were Leif and Marie Anderson, parents of the wife (Louise) of the son (Ian) of our very good friend (Paula in San Francisco). We had met them before in San Francisco, so they were not total strangers. After coming aboard briefly, they left to do errands. Lief returned around 4 p.m. to pick us up and drive us the short distance to their remarkably lovely house, surrounded by a colorful garden and with great views of the water. Marie had laid out an array of hors d'oeuvre, which we enjoyed with conversation. Then she presented dinner, with baked cod for the carnivores and homemade and delicious veggie patties for me, accompanied by several well-prepared vegetables. This was followed by a rich dessert of chocolate cake with cream and strawberries. Leif and Marie are extremely nice people, and we so appreciate their arranging docking for us and entertaining and feeding us in the lovely home.

We were off again the next morning (Friday, June 26), destination Gothenberg, which we reached in under three hours, arriving at 12:45 p.m. We only had a day to explore, so after lunch we went ashore. 

Peter was still exasperated with Garmin and the fact that charts would not download. He talked with a representative, who fortunately seemed knowledgeable; he advised Peter to buy new storage cards, so our first stop in the city was the enormous and popular mall directly across from the city marina. Then we went to the visitors center, where we obtained a map and guidebook and a lot of advise. Before setting off to the suggested places, we had ice cream by the equestrian statue of King Charles (Karl) IX, who reigned from 1604 to 1611. He established the original fortified town at the strategic location at the mouth of the Göta River for trade and defense.

We walked the short distance to Trädgårdsföreningen, a park and horticultural center. The park was founded in 1842 by King Carl XIV Johan and includes an acclaimed rose garden with about 4,000 roses of 1,900 species. There is also a 19th-century palm house as well as greenhouses and sculptures. There were many delightful things to see, including the giant water lilies the size and shape of kiddie wading pools.

After visting the ⁨Trädgårdsföreningen, we strolled past the university. We stopped to see the Haga Kyrka from the outside. (It was closed.) In the open area around the church we found a memorial to the hero Raoul Wallenberg, the Swedish diplomat who saved thousands of Jews and others in German-occupied Hungary during the Holocaust from the Nazis and Hungarian fascists during WWII.

From there we walked to Haga, the oldest suburb of Gothenburg, established in the 17th century. It is famous for its well-preserved 19th-century wooden houses and cobblestone streets. The neighborhood features a distinctive architectural style known as landshövdingehus, with the ground floor made of brick or stone and the two upper floors made of wood, as required by 19th-century fire regulations. We found a restaurant with high ratings and at al fresco. Luckily for me, it was one of those places where the chef puts as much effort into creating delicious and different vegetarian entrees as the meat and fish main courses.

After dinner, we climbed the hill Risåsberget to the redoubt Skansen Kronan, which was built to protect the city from possible Danish attack. Construction started in 1687 and the fortification was commissioned in 1698 and equipped with 23 guns. Huge stones of granite, gneiss and diabase were used to create the 4-5 meter thick walls. The redoubt was never attacked and the guns were never fired for military use. There are great views from the top of the hill.

We took a tram to the Gothenbrug Botanical Gardens, one of the largest botanical gardens in Europe. It was started in the early 20th century and opened to the public inn 1923. We visited various areas, including the greenhouse, the herb garden, the bamboo thicket, the fern hollow, and the perennial garden. The garden is always open; we left, after many hours of sight-seeing, at 10 p.m., making it back to Mantra, after some confusion about the location of the bus stop, at 11 p.m., where we dropped into bed.

Peter ran some errands the next morning, Saturday, June 27, and we both used the shower facilities of the marina. Peter ran onto the boat at 11:25 and asked if we could make the opening of the bridge just upstream of the marina at 11:35. We scampered around quickly and made it! Thus began our trip across Sweden via the Trollhättan and Göta Canals, with lakes in between large enough for whole days of sailing.

And that's where we are now, on Lake Vanern. Tomorrow I will continue.
