What's the biggest campsite selection mistake you've made and what did you learn from it?
I've been backpacking for a few years now and campsite selection is honestly one of those skills nobody really teaches you upfront. You just kind of learn through painful experience.
My worst call was setting up on what looked like a perfectly flat, sheltered spot near a creek. Woke up at 2am with water slowly creeping into my tent because I hadn't noticed I was sitting in a natural drainage channel. Gear soaked, sleep ruined, spent the next day hiking in damp socks. Totally avoidable if I'd taken five extra minutes to actually read the terrain.
Since then I check for subtle slopes, look uphill for signs of water flow paths, and avoid anything that looks too conveniently flat near water. I also try to arrive at camp with enough daylight to walk around and look at a few options before committing to one.
Curious what mistakes others have made. Weather, terrain, wildlife signs you missed, proximity to other campers, noise? The real lessons always come from the trips that went sideways, not the smooth ones. What would you tell a newer backpacker to watch out for first?
