Upper Geyser Basin

Must-See Attractions

Beyond its star attraction, Old Faithful, the Upper Geyser Basin features the highest concentration of geysers in the park—and the entire world. Yellowstone is home to 60% of the world's geysers. After witnessing Old Faithful's eruption, take time to hike around and discover over 150 hydrothermal features in the area.

Geographic Scope

The Upper Geyser Basin is expansive, stretching from Biscuit Basin in the north to Old Faithful in the south, and reaching Black Sand Basin to the east. Visitors can explore all these areas in one day, given that Biscuit Basin and Old Faithful are connected by trails, boardwalks, and a bike path (a bit over 3 miles apart). For those captivated by Old Faithful, other notable erupting geysers include Riverside, Daisy, Grand, and Castle. Estimated eruption times are available at the visitor center or via the NPS app. If colorful pools fascinate you, don't miss the Morning Glory Pool and the Sapphire Pool.

Advice from Recent Visitors

Recent visitors unanimously agree that Upper Geyser Basin offers much more than just Old Faithful. They marveled at the unique geothermal landscape and appreciated the convenient walkways leading to each natural wonder. Some visitors recommend planning your route in advance, especially if you're traveling with young children. Packing snacks or a picnic lunch enhances the outdoor experience.

Important Safety Information

The Upper Geyser Basin is located about 32 miles southeast of Yellowstone's west entrance. While there are no set hours for visiting, access to the basin is included in the park's seven-day admission fee ($35 per vehicle). It's crucial to stay on marked pathways and keep a close eye on children since pets are prohibited. Geysers and hot spring pools average around 200 degrees Fahrenheit, posing severe burn risks to those who get too close. Additionally, hydrothermal areas can emit toxic gases. If you start feeling unwell, leave the area immediately and report to an NPS staff member if possible.
