Program Overview: On this weekend adventure, you’ll join an experienced naturalist guide and fellow park fans to explore high-elevation habitats and experience the beauty of summer in the mountains. Start your weekend with a Friday evening program in Tuolumne Meadows, where you’ll get an introduction to the fascinating field of alpine ecology. On Saturday and Sunday, you’ll head out for day hikes in and around the Tuolumne Meadows area, covering 6 or 7 miles each day.

As you hike, you’ll learn about the life that thrives at Yosemite’s high elevations, including on “sky islands,” isolated plateaus that harbor rare plants found nowhere else on Earth. As you revel in majestic views of mountains, meadows and lakes — and pick up tips for future visits to this quiet part of the park — you’ll have endless opportunities to reconnect with the natural world and see what makes a Yosemite summer so special.
