Crystal Lake

The Monarch Lakes Trail takes you on a demanding journey through Sequoia National Park's less-visited Mineral King region, culminating at two stunning alpine lakes. You'll navigate through diverse terrain, from exposed, sagebrush-covered slopes with panoramic views of Vandever Mountain to pristine forests and rocky canyons. The trail's significant elevation gain leads to the picturesque Lower and Upper Monarch Lakes, nestled in a dramatic rocky cirque, offering a truly memorable experience of high-Sierra beauty.

Planning your visit requires some foresight; this difficult 9.6-mile (15.4 km) hike with 3259 feet (993 metres) of elevation gain typically takes around 5 hours and 37 minutes. Wilderness permits are necessary for overnight stays, and bear food storage lockers are available near the lakes. The best time of year to hike Monarch Lakes Trail is generally during the summer and early fall when the high-elevation route is clear of snow, but always check conditions before you go.

This trail is a regional classic, offering a unique "Mineral King flair" compared to other top hiking trails in Sequoia National Park. It's known for its superb scenery and the chance to spot wildlife, such as marmots, in the meadows. The Upper Monarch Lake even has a dam that contributes to downstream power generation, adding an interesting historical and functional layer to this natural wonder.
