(optional but good) Hot springs and steam vents line the shoreline at West Thumb Geyser Basin, Yellowstone Lake in the distance. — Geothermal pools steaming along the shore of Yellowstone Lake at West Thumb Geyser Basin.

West Thumb Geyser Basin sits on the western edge of Yellowstone Lake — where geothermal activity meets deep blue water in a way you won't see anywhere else in the park.

This was my first stop in Yellowstone, and it amazed me. I had no idea there were geothermal features actually inside the lake — it felt like discovering a hidden world.

Here, steaming vents and vibrant pools line the shoreline, bison sometimes wander through the mist, and the boardwalk trails bring you within feet of Yellowstone's raw geothermal power. It’s smaller than some of the other basins, but the setting makes it unforgettable.

Where to Find West Thumb

You'll find West Thumb in the Grant Village area, about 17 miles north of the South Entrance. It's an easy stop along the Grand Loop Road, especially if you're heading to or from Grand Teton National Park.

What You'll See at West Thumb

West Thumb is compact but packed with variety — you can walk the full boardwalk in about an hour, longer if you're taking your time with photos.

Top highlights:

Black Pool: A deep, vivid blue hot spring, surprisingly beautiful after a past temperature rise "killed" the colorful microbes.
Fishing Cone: The famous lakeshore spring where early anglers cooked fish caught from Yellowstone Lake — a Yellowstone legend (don't try it now!).
Lakeshore Geyser: Occasionally erupts from the lake’s edge, making for stunning photo moments.
Abyss Pool: One of the park’s deepest hydrothermal features, a mesmerizing blue sinkhole.
Thumb Paint Pots: Bubbling mud pots colored by acidic conditions.
Surprise Pool: A brilliantly blue hot spring with unpredictable activity.

Pro Tip: Early morning or late afternoon light makes the colors pop even more against the lake.

Stay Safe and Respect the Basin

West Thumb feels peaceful, but it’s still an active geothermal area — and not a place for shortcuts.

Essentials:

Always stay on the boardwalks. The ground can be thin and unstable.
Never touch the water. Many pools are near boiling temperatures (some over 200°F).
Respect wildlife. Bison have the right of way. Always.
Bring bear spray — even near busy areas.

While we were there, the Abyss Pool made national news after an unfortunate accident. Yellowstone’s beauty demands respect.

Download the GuideAlong App

We wouldn't have caught half the hidden details without the GuideAlong Audio Tour App. It uses GPS to automatically tell stories, facts, and tips as you drive — no cell signal needed. Highly recommended for Yellowstone and Grand Teton. They have a set for both destinations.

How Much Time to Plan

Expect to spend 1 to 1.5 hours walking the West Thumb boardwalks. Longer if you're serious about photography or just want to take it slow.

West Thumb is smaller than places like Old Faithful, but it’s the contrast of fire and water — steam vents pouring into the vastness of Yellowstone Lake — that stays with you. It's a side of the park you don't see anywhere else.
