Route Description for Heart Lake Trail
The alpine terrain awaits exploration, and the Heart Lake Trail boasts the perfect opportunity to do just that. This versatile trek beckons intrepid adventurers year-round! The summer months see the ideal opportunity to swim in the heart-shaped lake. Note the terrain up to the divide is exposed; check the forecast prior to your adventure, and dress accordingly! Though this path is well-loved, it is yet to be signposted, so adventurers will be directed by rock cairns, which can be hard to follow when the path is snow-cloaked. For easy navigation, we encourage hikers to download the trail GPS prior to their adventure.

Embark on your adventure along the Heart Lake Trail from the Castle Lake Trailhead off Castle Lake Road. Setting out from here, the Castle Lake Trail travels east over the Castle Lake Creek before diverting south along the eastern shore of Castle Lake. Wandering along the shoreline of the glacial lake, you will be overwhelmed by the views of the bounding craggy granite cliffs decorated with lush conifers. The crystalline waters mirror the surroundings on a calm day, offering a picture-perfect scene. Gradually traveling up an incline, the climb will intensify as it diverts you away from the waters.
Beyond this point, the path will become more primitive and difficult to follow. Using the trail GPS or following the rock cairns, the route will ascend the rocky meadows and up to several switchbacks. As you climb, be sure to admire the scene of Castle Lake below. Eventually, you will reach a saddle—veer right here, and you will be diverted onto the Heart Lake Trail. Trekking west, you will ultimately reach the shores of the heart-shaped lake. Admire the charm of Heart Lake and rejuvenate your tired feet in the chilly waters. Continue hiking west up to an overlook that affords jaw-dropping panoramas of Mount Shasta looming in the northeast. Admire the astonishing vistas, and when you are ready, carefully retrace your steps back to the trailhead.
