Young Lakes

Overview

Young Lakes is a trio of glacial cirque lakes (Lower, Middle, Upper) perched above Tuolumne Meadows, delivering sweeping granite views, subalpine forest, and broad meadows. It’s the kind of high-country payoff that feels bigger than the effort, with the option to turn it into either a solid dayhike or a relaxed overnight.

Routes & Difficulty

• Loop via Glen Aulin: about 14.3 miles with roughly 2,529 feet of gain; start at the Lembert Dome area and return via the Dog Lake side.
• Out-and-back via Dog Lake: around 13.5 miles round-trip with roughly 1,500–1,600 feet of gain—popular for a one-night backpack.
• To Upper Young Lake: from the Lower lake, a use path follows the stream past the Middle lake and includes a short but very steep section.
• If you just want to reach the Lower lake, plan on roughly 6–7 miles in with a little over 1,000 feet of ascent depending on route.

Camping & Regulations

Most backpackers camp at the Lower lake among scattered trees, while the Middle and Upper lakes offer more solitude and bigger vistas. Overnight trips require a Yosemite wilderness permit; standard trailhead choices are “Young Lakes via Dog Lake” and “Young Lakes via Glen Aulin.” A portion of permits is reservable well in advance, with additional permits released closer to the date. Bear-resistant food storage is required. Camp at least 100 feet from water and trails and follow current fire regulations (rules change with season and elevation; check on arrival).

Fishing & What You’ll See

Angling can be rewarding across the basin; many hikers call this a great spot to cast a line, with some reports noting the Middle lake as a strong producer. Expect classic Sierra scenery: polished granite, airy meadows, and big sky reflections on all three lakes.

Logistics: Parking, Water, and Trailheads

Trailheads cluster around Tuolumne Meadows. You can start from the Dog Lake side or the Glen Aulin/PCT side near Lembert Dome; signage and map labels can be confusing, so double-check your lot. Water is plentiful from creeks and the lakes—carry a filter and top off often. Frontcountry conveniences like restrooms and a water spigot exist near the Tuolumne Meadows Wilderness Center; once you’re on trail and in the basin, you’re in true backcountry with no services.

Seasonal Notes & Safety

The season is governed by Tioga Road—prime time is roughly June through October, though early season can still mean lingering snow. Expect mosquitoes in mid-summer; a head net and repellent can save the trip. The main trail is straightforward to the Lower lake, but above it you’ll encounter use paths and some steep, rocky sections—slow down if you’re carrying a pack.

Best Time to Visit

• When: Late summer to early fall for dry trails and fewer bugs; early season may hold snow.
• Days: Weekdays tend to be quieter; midweek in peak season can feel pleasantly empty.
• Timing: Start early for easier parking and cooler hiking.
• Photography: Sunset plays especially well at the Upper lake, with wide-open alpine views and calm evening reflections.

Extra Planning Tips

• Tioga Road typically closes to overnight parking after mid-October. If you’re planning a late-season trip, arrange a drop-off or transit.
• If you like staging before/after, note Tuolumne Meadows backpacker facilities are undergoing a remodel; Yosemite Valley’s backpacker campground may be your fallback.
