About Monument Geyser Basin

Monument Geyser Basin is a striking hot spring area tucked within Yellowstone National Park, showcasing intense geothermal activity in a remote setting. Its steamy pools and vibrant mineral deposits create a dramatic landscape that feels untouched by heavy tourism, inviting you to explore a more primitive side of Wyoming’s hot springs.

Getting There

Reaching Monument Geyser Basin demands a challenging hike of over an hour through rugged terrain, making the journey as rewarding as the destination. Parking near the trailhead is limited, so arriving early is essential to secure a spot. The trail tests your stamina but immerses you in Yellowstone’s wild beauty.

What to Expect

The basin features water heated to around 197°F, creating bubbling pools and steam vents surrounded by colorful mineral crusts. Expect minimal crowds, offering a quiet, almost meditative atmosphere far from the busier hot springs in Wyoming. Facilities are nonexistent, emphasizing an authentic experience with nature as it is.

Tips for Visitors

Wear sturdy footwear and bring plenty of water for the strenuous hike, as amenities don’t extend beyond the parking area. Admission to Yellowstone National Park is $35, so plan accordingly. Clothing is required for soaking, but note that swimming isn’t safe here—the extreme temperatures limit this spot to viewing and appreciating Wyoming swimming holes from a respectful distance.
