Castle Lake to Heart Lake, Shasta-Trinity National Forest, Mt. Shasta City, CA
Distance: <2.5 RT
Elevation Gain: ~680 ft
Difficulty: Easy to moderate, depending on your fitness level and sensitivity to altitude (5k-6k ft)
I discovered another gem of a hike in the Shasta-Trinity National Forest, some have called it one of the premier hikes in the region. I guess I know how to pick them. It’s easy on effort and short on distance, but long on rewards. Especially if you’re into alpine lakes, reflection shots, and great views of Mt. Shasta, Black Butte, and Mount McLoughlin.
The single-track trail winds through a few rocky stretches, gradually climbing to captivating Heart Lake at an elevation of 6,050 ft, where you’ll be dazzled by the reflections.






If you have more time than I did, you can take dip in any of the lakes, hike the spur trail to Little Castle Lake (add 2 miles RT and a steep 250 ft climb) or continue to Mount Bradley (add 8 miles RT).
(I had less than 2 hours to sneak in a hike before dashing to the airport, so I wanted to make the most of it. Mission accomplished with this lovely hike that I paired with the super shortie hike just down the road on the way back to town—enchanting Faery Falls.)

Happy Trails!
Leave No Trace.
Stay on the obvious main trail and avoid cutting switchbacks and taking social trails, as these are damaging the sensitive Alpine area.
