Program Overview: On this guided overnight trip, you’ll get to experience a natural treasure — Yosemite’s night skies — during the largest meteor shower of the year!

After meeting up with your trip leader and fellow adventurers, you’ll hike about a mile and a half from the Ostrander Lake Trailhead (along Glacier Point Road). You’ll set up camp at a spot with a clear view of the sky, at an elevation where it won’t get too cold to sleep outside under the stars. As night falls, your naturalist guide will point out constellations, and you’ll get to search the sky for distant planets and meteors — all from the comfort of your sleeping bag. Watch for the bright meteors of the Perseids shower, as debris from the comet known as Swift-Tuttle blazes into Earth’s atmosphere. The Perseids peak in mid-August — perfect timing for this one-night adventure!

Pack your sleeping gear, a tent (just in case!) and simple meals, such as premade sandwiches, and prepare to be dazzled by what you can see in just one night out in the mountains.
