Select participants and date
You start on granite and almost immediately the canyon begins to talk. Guides here ask you to loosen your shoulders, breathe the cool air, and read the landscape: a braided history of ice, river, and time. For three hours, a small group moves with purpose—playing a quick “Forest Forensics” game to tune senses—then spreads out beneath the face of El Capitan and near the thunder of Yosemite Falls. The valley’s proportions make you small, but they also sharpen attention.

Adventure Tips
Bring layered clothing
Valley temperatures swing quickly; mornings can be chilly while midday warms on exposed granite—dress in layers you can remove easily.
Wear grippy footwear
Expect uneven granite slabs and short scree sections—trail runners with good traction or light hiking boots work best.
Hydrate before and during
Carry at least 1–1.5 liters of water; high-exertion and dry air increase fluid needs even on cool days.
Follow food-storage rules
Bring snacks in bear-resistant containers or follow guide instructions—do not leave food unattended on trail.
