We asked for instructions from our hotel. This is what they said:
Hello,
When you arrive in Lauterbrunnen, look for a beautiful tall waterfall at the southern edge of town. Go in that direction down the main street (you are already on it, it is the only one in town). Continue through town and after 500 meters you will see our hotel on the left. If you pass the church you have gone too far.
See you soon!
Craig
We’re excited about staying here now.
