No spiritual or individual experiences in particular, but I go backpacking often. However, I tend to get altitude sickness pretty easily so the second day of backpacking while everybody goes day hiking, I usually hang out at a lake—sometimes take a short hike to a bluff, find a nice rock in the sun, put some sunscreen on, and enjoy the view while reading a book. No ipod, no noise, no people, no computer, and no TV.
