I will be backpacking with camping gear this July (3 season ultra lightweight tent, zero degree sleeping bag, all needed camping gear) and am an experienced backcountry hiker/camper. I'd like to sleep out under the stars (if skies are clear) or in my tent (if raining) south of Colmar, France or near Neuchatel just over the border in Switzerland. Would love information on whether backcountry camping areas exist in the hills/forests south of Colmar and to the east near the border with Switzerland. If so, any info on protocol (advance reservations, restrictions, etc.) would be of tremendous help. I know there are campgrounds in Neuchatal, Switzerland - but these are "car camping" sites with hostels, etc. nearby. I'm looking to go full-on backcountry for a few days when not in Colmar or the villages near La Rue du Vin. Thanks!
Generally speaking, in Switzerland wild camping is not allowed in forests or inhabited areas including valleys and hill areas. If you are camping in the mountains above the treeline then it might be allowed but usually only for one night in any given place. It's definitely not allowed in any wildlife or conservation areas. The rules are set by each local authority. For specific information the Swiss Alpine Club is your best source.
