Some campers are just overachievers. They need to go farther, get higher, or move faster. It's not enough for these outdoor sleepers to crash in the middle of the woods or out in the desert. They're looking for a more thrilling way to catch some z's—and some of them are finding it in the sky.
For rock climbers, a portaledge means they can tackle multi-day ascents up terrifyingly tall walls. For backcountry campers, a tree tent provides a comfortable respite from the cold, hard ground—and an escape from any wandering critters. For slackliners, hanging hammocks give them a space to get off their feet and enjoy hard-earned panoramic views.
