I camp at campsites alot and must confess i have never seen anyone using a tarp / bivi at a campsite is it allowed or is it that people who tarp only really wild camp. The reason i ask is that one day (when the pesky kids and wife allow me) i would like to do some long distance walks such as the anglesey coastal path and others and whilst most nights i plan to wild camp there will be the odd night i want a shower and some amenities. I would like to do this with a tarp bivi set up i guess camp security may be an issue but has anyone done this or would it be best to resort to my wee tent?
