Theres is public parking outside of the actual campground. You'll then hike through the campground to get to the Lonesome Lake trail.
Kelley, not in the park, but in one of the 3 parking areas at the entrance. But get there early.
Openhisword is correct. Make sure to hike around the lake if you have a chance!!
Openhisword is spot on with his answer. Have the best time! The hut is fantastic
