Visit MotoCentre Thun for a great coffee
Stunning ride along the edge of the lake
The most stunning village on the face of the planet. Stay at the Village Hostel NOT the camping ground. Take the train up to Jungfraujoch.
A series of 11 waterfalls running INSIDE the mountain. Get the lift to the top and then walk down the stairs inside the waterfalls. Just stunning. Make sure you go to the loo before you go up in the lift and rug up warm even in summer.
Catch the gondola up to Gimmelwald on the top of the ridge and stay the night at the hostel.
A great day trip from Lauterbrunnen on well sealed not too twisty roads. Have hot chocolate at the road block.
