We are staying in Lauterbrunnen and Murren and would like to tandem paraglide. Do we have to go all the way to Interlaken? Any tips on where is the best area to go? Best company? Any to avoid? Thanks for your help!
No, you don't have to go to Interlaken. One of the locations used for launching flights is a hillside just above Mürren, and launching from the Schilthorn should also be offered (longer flight but more expensive).
One firm you might contact is http://airtime-paragliding.ch/
They have excellent ratings on Trip Advisor.
