The Lottis Creek Campground is by far the most common approach, and is the approach described here.
Need to Know
Five miles from the campground, the South Lottis Trail #428 comes to a fork with the Henry Lake Trail #429. Turning right, the route continues along South Lottis Creek, ascending a shallow basin below Henry Mountain.
The elevation climbs more rapidly throughout this segment, with only two miles to gain the final 1,000 feet to the lake, compared to the 1,600 feet of gain conquered over the course of the previous five miles along the South Lottis Trail #428.
1.5 miles from the split, the woods grow sparse as treeline nears, bringing with it your first good views of the 13,254 foot Henry Mountain, which makes up the southern wall of the basin. After a brief respite, the final half-mile grind to the northern inlet of Henry Lake at 11,704 feet brings with it a grueling set of switchbacks.
Topping out, the high clearance allows for wide views into the heart of the Sawatch Mountain Range, most notably Jenkins Mountain and Grizzly Peak. From the lake, head back the way you came or continue south along the South Lottis Trail #428 to the Gold Campground for a point-to-point shuttle.
