Turbid Lake Trail

Overview

If you’re after Yellowstone solitude with a side of funky geology, Turbid Lake delivers. This remote day hike leads to a large, murky lake influenced by thermal activity—think hot springs and occasional sinkholes near the shoreline—set in quiet forest and meadow country on the park’s east side. Expect a lightly maintained, at times faint path and the very real possibility of sharing the landscape with bison and grizzlies.

Distance, Elevation, and Time

The standard out-and-back from the Nine Mile Trailhead is about 10.0 miles total with roughly 974 feet of gain. Strong hikers often clock it in around 4 hours, but build in buffer for route-finding and wildlife delays. A shorter variation via Pelican Valley runs about 8.3 miles, while an ambitious continuation toward the Pelican Creek junction can push the outing into the 20+ mile range—only for experienced navigators.

What It’s Like

The route follows old roadbed and singletrack through patches of old-growth forest and open meadows before reaching the lake’s turbid, thermally influenced waters. The tread can be overgrown and indistinct, signage is sparse, and blazes can be hard to spot—download an offline map and bring a GPS/compass. Bugs and the occasional thistle patch show up seasonally; long pants are a good call.

Wildlife and Safety

This is prime grizzly and bison habitat. Hike in a group if you can, make noise, carry bear spray, and know how to use it. Give wildlife plenty of space and be prepared to wait or turn around if animals are on the trail. At the lake, stay off fragile thermal features near the shore. Dogs are not allowed.

Best Time to Hike

May through October is the typical window. Early and late season can bring snow or mud. Start early for cooler temps, more wildlife awareness time, and flexibility if you need to detour. If you’re approaching via Pelican Valley, check for seasonal access restrictions that can affect timing and route options.

Access and Parking

The primary start is the Nine Mile Trailhead on the East Entrance Road. Park in the signed area and start from there. Check for any posted requirements—parking is available at the trailhead, and a permit may be required.

Who Will Love It (and Who Won’t)

You’ll love this hike if you’re comfortable navigating faint tread for a genuine backcountry feel and want a rare look at a thermally influenced lake far from the boardwalk crowds. If you prefer well-marked, highly maintained trails or guaranteed payoff views, consider other options in the area. For more wildlife-forward hiking on a broader path, the Pelican Valley approach is a worthy alternative when open.
