Im heading to Interlaken Switzerland around Mid-September time frame. I love the outdoors and have been through there once, but didnt get a chance to do anything. I was wondering if anyone had any tips for things to do while there. I plan on bungee jumping, canyoning and doing a lot of hiking. Im spending a week there. Anyone know of any good hikes in the area? Also, what will the weather be like. Im wondering if I need to pack some warm clothes.
