Yosemite Mountaineering School

Overview

This is Yosemite’s original climbing and backcountry guide service, operating since 1969 with deep roots in the Valley’s climbing history. If you want to try granite crack climbing, nail a classic multi‑pitch, or have someone handle permits and route‑finding for a big hike or backpack, this is the outfit. They’re the only authorized climbing guides operating inside the park and put a big emphasis on safety and sound instruction.

What They Offer

• Rock climbing: half‑day, full‑day, multi‑day, and custom days for all levels.
• Guided hiking: anything from a few hours to full‑day objectives (including big marquee hikes).
• Backpacking: multi‑day trips with permits, meal planning, and skills coaching (navigation, safety).
• Winter: cross‑country ski lessons and guided XC/snowshoe outings from Badger Pass.

How It Works

• Most climbing programs run about seven hours and meet at 8:30 am.
• Small groups: typically up to six students per instructor; private days available.
• Classes are designed to build sequentially over multiple days if you want faster skill progression.
• Age guidelines: 12+ can join regular classes; ages 10–11 can join with a supervising adult; under 10 requires a private lesson with an adult.
• Guides hold Wilderness First Responder or Wilderness EMT certifications and are known for tailoring objectives to mixed abilities and comfort levels.

Where You’ll Meet

Base locations are in Curry (Half Dome) Village in Yosemite Valley and in Tuolumne Meadows (seasonally). In winter, programs operate from Badger Pass. There are restrooms at the office and a small shop on site for swag and essentials.

Best Time to Visit

• Peak season fills quickly—reserve as early as you can.
• Mid‑summer can be scorching on Valley granite; Tuolumne Meadows is typically the cooler, breezier choice.
• Winter shifts to XC skiing and snowshoeing from Badger Pass; book around storms for the best snow.
• For photos, morning light is friendlier on Valley routes that get early shade; full‑day programs mean you’ll touch a range of conditions.

Is It Worth It?

If you value legit instruction, safety focus, and insider route choices on world‑class stone, yes. Prices can sting, and experiences can vary a bit by guide, but the high bar of professionalism and the convenience of in‑park guiding make it a strong pick for first‑timers and seasoned climbers alike.

What To Bring

Plan for a full day: at least 2–3 liters of water, snacks, a packed lunch, sun protection, and layers. Share your goals and experience during booking so your guide can tailor the day—especially helpful for mixed‑ability groups.
