Hiking in Granite & Hidden Lakes Trail: trails, map and practical info

The Granite and Hidden Lakes Trail is one of those hikes that earns its reputation the hard way — through real elevation, genuine alpine scenery, and a payoff that makes every step worth it. This trail leads you through classic mountain terrain to two distinct lake destinations, each with its own character and appeal. Whether you're aiming for one or pushing through to both, this route delivers the kind of backcountry feel that keeps hikers coming back.

The Terrain

The trail climbs steadily through forested slopes before opening up into more exposed alpine terrain. As you gain elevation, the tree cover thins and the views start to open up around you. The path transitions from shaded woodland trail to rocky, open ridgeline walking — the kind of terrain where you're picking your way between boulders and patches of wildflowers depending on the season.

Granite Lake sits in a classic cirque setting, surrounded by the kind of rugged, angular rock that gives the lake its name. The water is typically clear and cold, reflecting the rocky walls above. Hidden Lake lives up to its name — it requires a bit more effort to reach and feels more tucked away, more private. The approach to Hidden Lake tends to be steeper and less traveled, which adds to the sense of discovery when you finally arrive.

What to Expect on the Trail

This is not a casual stroll. The trail demands solid footing and a reasonable baseline of fitness. The rocky sections require attention, especially if conditions are wet or if there's any lingering snow. Trekking poles are genuinely useful here — not just for the climb up, but for the descent, which can be hard on the knees on the steeper pitches.

The trail is well-defined for most of its length, but there are sections — particularly as you approach Hidden Lake — where route-finding requires a bit more attention. Keep an eye on trail markers and don't rely solely on a single navigation source. A downloaded offline map is a smart move before you head out.

Expect to share the trail on weekends, especially the lower sections leading to Granite Lake. The further you push toward Hidden Lake, the fewer people you'll encounter. If solitude is what you're after, an early start on a weekday is your best bet.

The Lakes

Granite Lake is the more accessible of the two and tends to be the turnaround point for hikers who want a solid outing without committing to the full route. It's a great spot to take a break, eat lunch, and take in the surrounding peaks. The shoreline offers several flat rocks that work well as rest spots.

Hidden Lake is the reward for those willing to push further. The extra effort filters out the crowds, and the setting feels more remote and wild. The lake sits in a quieter basin, and on calm days the surface can be remarkably still. It's the kind of place that makes you want to sit for a while before heading back down.

Wildlife and Nature

The alpine and subalpine zones along this trail support a range of wildlife. Marmots are commonly spotted in the rocky sections, and you may hear their sharp warning calls before you see them. Pikas are also present in the boulder fields — listen for their distinctive high-pitched calls. Birds are active throughout the trail, particularly in the forested lower sections.

The wildflower display in the open meadow sections can be impressive during peak season, with a mix of species adapted to the short alpine growing window. The rocky terrain around both lakes supports hardy vegetation that adds texture and color to an otherwise stark landscape.

Practical Information

• Footwear: Sturdy hiking boots with ankle support are strongly recommended. Trail runners can work for experienced hikers comfortable on rocky terrain, but this is not a sneaker trail.
• Water: Carry enough water for the full outing. There are water sources along the route, but always treat or filter any water collected in the backcountry.
• Weather: Mountain weather can shift quickly. Even on a clear morning, afternoon thunderstorms are a real possibility in alpine terrain. Start early and be prepared to turn around if conditions deteriorate.
• Navigation: Download an offline map before you go. Cell service is unreliable in the backcountry sections of this trail.
• Leave No Trace: Pack out everything you bring in. The alpine ecosystem around both lakes is fragile — stay on established trails and avoid trampling vegetation near the shorelines.

Getting There

Check current access conditions and any permit requirements before heading out, as trailhead access and regulations can change seasonally. Arriving early is advisable on busy weekends, as trailhead parking can fill up quickly during peak hiking season.

Who This Trail Is For

The Granite and Hidden Lakes Trail is best suited for hikers with some experience under their belts. It's not the right choice for a first-time hiker or young children who aren't used to sustained climbs on uneven terrain. That said, fit and motivated hikers of a wide range of ages tackle this route successfully — it's challenging but not technical. If you've done a handful of mountain hikes and you're comfortable on rocky trails, this one is well within reach.

For those who want to extend the experience, the area around both lakes offers opportunities to explore beyond the main trail, though you should always be confident in your navigation skills before leaving the marked route.
