Henry Lake via South Lottis Trail

The most common approach to Henry Lake is via the South Lottis Trail, which starts near the Lottis Creek Campground. You'll find parking available at the trailhead. It's always a good idea to arrive early, especially on weekends, to secure a spot.

Yes, the trail is generally dog-friendly. However, as it's located within the Fossil Ridge Wilderness, please ensure your dog is kept on a leash to protect wildlife and respect other hikers. Always pack out any waste.

The best time to hike this trail is typically from late spring to early fall, roughly June through September, when the snow has melted and the wildflowers are in bloom. Be aware that early season hikes might involve challenging high water crossings at Lottis Creek, and late season can bring colder temperatures and early snow.

Generally, there are no permits or entrance fees required for day hiking in the Fossil Ridge Wilderness. However, regulations can change, so it's always wise to check the USDA Forest Service website for the latest information on specific area regulations or potential fire restrictions before your trip.

The terrain varies significantly. You'll start with an initial crossing of Lottis Creek, which can be high. The path then follows South Lottis Creek through thick woodlands of aspen and pine, often on an old mining road. As you get closer to Henry Lake, the trail becomes increasingly rocky and exposed, with a rapid, steep ascent including switchbacks to reach the lake basin. Expect some boggy areas as well.

You'll traverse lush old-growth forests, vibrant wildflower meadows, and enjoy glimpses of Broncho Mountain. Key highlights include the stunning Lamphier Lake (if taking a longer route), Gunsight Pass, and the ultimate reward, Henry Lake itself, nestled beneath Henry Mountain. From the lake, you'll have expansive views into the Sawatch Mountain Range.

The Fossil Ridge Wilderness is rich in wildlife. Hikers often report sightings of elk, deer, bighorn sheep, and mountain goats. You might also spot smaller animals like fox and bobcats, and occasionally even mountain lions. Always maintain a safe distance and never feed wildlife.

This trail is generally considered difficult due to its significant length (over 16 miles round trip), substantial elevation gain (over 4,600 feet), and rugged, steep sections, especially the final push to Henry Lake. It's not recommended for beginners. Hikers should be well-prepared, in good physical condition, and acclimated to high altitudes.

Be prepared for a potentially challenging initial crossing of Lottis Creek, especially during high water periods in late spring/early summer. The final two miles to Henry Lake involve a rapid ascent of about 1,000 feet, with a particularly grueling half-mile of switchbacks. It's crucial to carry plenty of water, as sources can be limited or require filtration, and be aware of changing weather conditions at high altitudes.

Yes, the route primarily follows the South Lottis Trail and the Henry Lake Trail. It also briefly intersects with sections of the Fossil Ridge Trail, Gold Creek Road, and Mill Lake Trail, offering options for extended exploration within the wilderness area.

Yes, both Henry Lake and Lamphier Lake are known for good fishing opportunities. Make sure you have a valid Colorado fishing license and are familiar with any specific regulations for high-altitude lakes in the area.
