Grizzly Lake Trail

Overview

Grizzly Lake is a moderate out-and-back that trades Yellowstone’s crowds for big sky and a peaceful shoreline. Expect a short, punchy climb, airy meadows, young lodgepole forest, and a final steep drop to the lake. The standard route runs about 4.3 miles round trip with roughly 770–800 feet of total gain. If you prefer to keep it easier, turn around at the overlook near the high point instead of dropping to the water—the descent to the shore is steep and makes the return climb feel longer.

Trail Snapshot & Route Options

• Standard route (from the signed Grizzly Lake trailhead): ~4.3 miles round trip, ~770–800 ft gain, out-and-back. The path climbs via tight switchbacks, rolls through meadows and burned/unburned forest, then descends to the lake.
• Alternate approach (from Mount Holmes Trailhead): ~9.2 miles round trip, ~780 ft gain, out-and-back. It’s typically quieter but can involve several cold, ankle-to-shin–deep creek crossings early season.

What You’ll See

From the initial switchbacks you’ll snag sweeping views toward the southern Gallatin Mountains, with Mount Holmes and Antler Peak anchoring the skyline. The landscape here sits between Roaring Mountain and Obsidian Cliff—country shaped by Yellowstone’s silica‑rich rhyolite volcanism—so expect nutrient‑poor soils, open meadows, and young lodgepole stands recovering from past fires. At the lake, look for marmots among talus, birds working the shoreline, and classic reflections when the wind lies down.

Conditions to Expect

Early season (late spring into early summer) can be marshy and muddy with small creek crossings; snowmelt can push water levels up and make those crossings chilly. Bugs can be fierce on calm days and near water, especially before late summer—bring repellent and consider long sleeves. By late summer into fall, trails firm up and the meadows glow; it’s the best window for dry feet and fewer mosquitoes.

Best Time to Hike

June through October generally offers the best conditions. Start early for cooler temps, easier parking, and calmer water for photos at the lake. Late September can deliver pretty fall color, but weather swings quickly—pack layers and a rain shell.

Wildlife & Safety

This is true bear country. Grizzly bears frequent the area, and hikers also report elk, bison, wolves, and marmots. Hike in a tight group of three or more, make noise in brushy sections, carry bear spray where you can grab it fast, and know how to use it. Stay at least 100 yards from bears and wolves, and 25 yards from other wildlife. If a bear charges, stand your ground and deploy spray; if contact is made, play dead. Give all animals space—never approach or feed wildlife.

Access, Rules, and Tips

• Trailhead: Small roadside pullout on the Grand Loop Road between Roaring Mountain and Obsidian Cliff; parking is limited—arrive early.
• No pets on trails or in the backcountry; no bikes, strollers, or motorized/wheeled devices (wheelchairs excepted). Stay on established trails.
• Fishing is allowed with a Yellowstone permit; overnight backcountry trips require a permit. Pack out all trash and bury human waste properly where allowed.

Is It Worth It?

Yes—if you want a short, view‑rich hike to a quiet lake without elbow‑to‑elbow crowds. The steep drop to the lake adds effort on the way out; if that’s not your vibe, enjoy the overlook and call it good. For a longer, quieter day with some adventure, the Mount Holmes approach is a solid upgrade—just be ready for cold crossings early season.
