Distance - .5 mile boardwalk trail

Location - 1 mile north of Old Faithful area on the Grand Loop Road.

Look for black obsidian around the edges of the pool. This black obsidian was what brought early visitors to name this area Black Sand Basin.

Black Sand Basin is split into a Y-shaped boardwalk. It is is a really short distance between all of the thermal features and hot springs.

There isn't a ton of shade on this boardwalk. If you are visiting during the hot summer make sure you are ready for the sun. If you visit later in the day you may want bug spray. We encountered a few mosquitoes while exploring the boardwalk.

6-Mile Geyser Hiking Tour in Yellowstone with Lunch
⭐️ Rating: 4.9 out of 5 Stars (93+ reviews) | ⏳ Tour Length: 6 hours | 🥾🌋
Check Rates and Availability

Most visitors to Yellowstone spend their time at Old Faithful watching the eruption from the crowded viewing area and then heading back to the parking lot. This tour goes somewhere completely different. Starting at the Daisy Geyser Trailhead and following the Firehole River through the Upper Geyser Basin, your guide takes a small group of up to 14 guests past hissing steam vents, vivid hot springs, and geysers that most park visitors walk right past without knowing what they are looking at.

The route covers 6 miles and about six hours on your feet, passing Grotto Geyser, Observation Point, Daisy Geyser, and a climb up to the Observation Point overlook above Old Faithful where reviewers consistently say the view puts the standard ground-level crowd experience to shame. One reviewer watched Old Faithful erupt twice from two completely different vantage points on the same tour. Another caught Grand Geyser erupting up close after their guide rerouted around a bison blocking the trail.
