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 from the May Lake Trailhead. 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 will use a laser pointer to single out specific stars and constellations, and you’ll get to search the sky for distant planets and meteors — all from the comfort of your sleeping bag. The program curriculum focuses on astronomy (including but not limited to star science, constellations, planetary science, perception of light/how light travels, meteors, meteorites, etc.), as well as story/lore/mythology rooted in cultures both locally and across the world. 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, coinciding with the new moon cycle — this is the 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.
