Holly Lake

Overview

Holly Lake is a classic high-alpine tarn tucked into Paintbrush Canyon beneath Mount Woodring, sitting around 9,400 feet. It’s remote, rugged, and gorgeous—the kind of place that feels earned. Expect crisp air, stark granite, and that shimmering, cold-blue water that only glacial lakes have.

Getting There & The Hike

You’ll reach the lake via the Paintbrush Canyon route starting from the String or Leigh Lake trailheads. It’s a full-day outing for most: roughly 12.4–12.8 miles round-trip with about 2,750–2,840 feet of climbing, typically taking 7–9 hours. The trail climbs steadily from forest and meadows into open, rocky upper canyon terrain. The final approach is dramatic, with big views and some steeper, rougher sections underfoot.

What You’ll See

• Panoramic alpine scenery, with rugged ridgelines framing a pristine glacial lake.
• Seasonal wildflowers lighting up the meadows and slopes in summer.
• From certain vantage points along the approach, long views down-canyon and toward distant valley lakes.

Pro tip: there’s a small pond near a junction below the final climb—many hikers consider it a particularly pretty rest spot.

Wildlife

You’re in active bear country here (both black and grizzly). Marmots and pikas are commonly seen around the rockfields, and deer and a variety of birds frequent the area. Carry bear spray and know how to use it, and follow Leave No Trace throughout.

Camping & Permits

Holly Lake is a popular target for both day hikers and backpackers. Overnight stays require a backcountry permit, and camping is restricted to designated zones near (but not at) the lake. It’s also a common staging point for longer itineraries like the Paintbrush–Cascade loop.

Conditions & Safety

Snowfields can linger into mid-summer; what feels hot at the trailhead can turn cool and snowy near the lake. The route traverses rocky, uneven terrain, so sturdy boots (and trekking poles if you like them) are smart. There are no services—no toilets, no potable water—so bring everything you need and treat natural water if you refill.

Best Time to Visit

Summer through early fall is the sweet spot—after snowmelt and before early-season storms. Start early to beat afternoon thunderstorms and give yourself daylight margin. Weekdays typically feel quieter than weekends on this popular but strenuous route.

Know Before You Go

• No pets on this trail.
• Park entrance fees apply; the hike itself is free.
• Backcountry camping is by permit only in designated zones.
• Check current trail and snow conditions before you commit to the upper canyon.
