Im a swimmer and i do a ton of hiking in the mountains behind my house usaly about twice a month on the wekends my best friend and me go out and hike like 12-20 miles depending on the waether in the summer we live up there .put on the pack and go out for like 4 days its fun but man if you need perfectly clear water dont do it .idoine tablets work but you get some funky stuff floating in there
