DeLacy Creek Trail

Overview

A mellow classic with a big payoff: this out-and-back follows DeLacy Creek through pine and spruce into open meadows before reaching the broad, quiet north shore of Shoshone Lake—the largest backcountry lake in the Lower 48 without road access. Plan on 5.8–6.0 miles total out-and-back with about 300 feet of gentle gain. Most hikers touch the beach, soak up the view, snack, and turn around.

What to Expect

The tread is mostly easy and well-defined, with soothing creek sounds, pockets of shade, and wildflower meadows that feel a world away from the boardwalk crowds. Near the lake, the flats can be marshy; if it’s soggy, many hikers walk the firm beach to keep feet dry. Expect occasional muddy patches and notable mosquitoes—especially on calm days.

Difficulty and Who Will Like It

Generally easy to easy-moderate thanks to friendly grades and modest elevation change. It’s a great leg-stretcher between geyser stops and a confidence-building hike for families or mellow miles seekers. If you push beyond the day-hike turnaround into the Shoshone Lake loop, the character changes: narrower, slipperier tread, steeper bits on the east side, swampy sections, and true creek fords.

Wildlife and Geology

This is prime habitat for moose and elk in the meadows and along the creek, plus sandhill cranes and other birds around the shoreline. Keep your distance and carry bear spray; you’re in grizzly country. Far beyond the standard day hike sits the remote Shoshone Geyser Basin—proof that Yellowstone’s volcanic engine hums here—so always stay on established paths around any thermal ground.

Best Time to Hike

Mornings are your friend: cooler temps, softer light on the meadows, fewer people, and less bug pressure if a breeze kicks up. Peak summer brings the most mosquitoes; shoulder-season mornings can be glorious but expect lingering wet ground after snowmelt or rain.

Tips

• Start early, wear long sleeves, and bring effective repellent; a head net can turn a buggy day into a pleasant one.
• Waterproof or quick-dry footwear helps with wet grass and mud; trekking poles are handy in slick spots.
• If you’re tempted to continue around the lake, be prepared for fords, swampy sections, and rougher tread; know the route and carry proper backcountry gear.
• Standard park rules apply: hike in groups when possible, make noise in blind areas, store food properly, no pets on trail, and no off-trail travel in thermal areas.
