If you travel by boat to the far end of Konigssee and get off at Salet, it is about a 10 minute walk to the Obersee. The lake here is surrounded by mountains making the surface normally completely still. It is a photographer’s paradise making for some wonderful reflection shots. During the Nazi era Eva Braun use to swim in the lake and Hitler made a number of visits to the lake.
The Röthbach Waterfall can be reached via a boat trip across the Konigssee and getting off at the end of the journey at Salet. You then have to walk to the Obersee and it is up to you how close you want to get to the waterfall, it certainly looks spectacular from a distance. The Röthbach Waterfall is the highest waterfall in Germany with a vertical drop of 470 metres.
A boat trip on the Konigssee is certainly a worthwhile just for the beauty of the area. The electric boat quietly takes you across the crystal clear 8km long lake. On your trip, the boat will stop and a member of the crew will blow a horn with the sound echoing back towards the boat. If you are a climber you can arrange for the boat to stop at Kessel. Most people get off the boat at St Bartholoma to have a wander around and look at the church and hunting lodge. If you wish you can walk to the SS. John and Paul chapel which takes 30 minutes or further on to the Ice Chapel at the eastern foot of the Watzmann Mountain which takes a further 60 minutes. If you stay on the boat the last stop is Salet. If you leave the boat and walk on for 15 minutes you will reach the Obersee which is a beautiful lake for photography because of the reflections created by the mountains. You can obtain refreshments at both Salet and St Bartholoma and there are toilets at both locations. . The boat trip is very popular and the boats can be crowded first thing in the morning when they start going out and again later in the day on the return journey. You can check the website for times and prices. One of the deals after 2pm is a round trip to St Bartholoma plus coffee and cake for 16 euros. More information can be obtained from the website.
The Ice Chapel is about 6km from St Bartholoma. You follow the trail from the National Park Information Hut to Kapelle St Johann und Paul. Having gone past the Chapel you continue uphill through the woods until you reach the large avalanche snow field at the foot of the Watzmann's east wall. The ice chapel changes from year to year in shape and size. I got there about 11.30 hours and for 30 minutes I had the entire place to myself. Strong shoes or boots are needed. You have to return the same route and then try some fish for lunch back at St Bartholoma
