As the summer settles in for more consistent spells of warm weather, high country trailheads become ever-more appealing respites from the swelter. Trails that have vanished for the winter beneath nourishing snows wait to greet you like old friends, or perhaps new ones that keep you exploring unfamiliar terrain. Leaving the lower elevations behind for these seasonally accessible areas means cooler, fresher air in your lungs, clear night skies, and with any luck, a refreshing mountain lake in which to swim. There's no shortage of higher elevation adventures to peruse on Outdoor Project, but here's a little sample to start the process. Remember that the Nearby Adventure section at the end of each adventure page can help you plan an itinerary of additional and similar adventures. And don't forget to tell us about your experience in the trip comments. Happy hiking!
