As Yellowstone’s peak visitation ramps up for summer 2025, one of its most “Instagrammed” attractions, Biscuit Basin, remains off-limits. Park officials have kept the boardwalk fenced off “until further notice,” following a hydrothermal explosion on July 23, 2024, that obliterated the basin’s iconic biscuit-shaped mineral deposits. Visitors arriving this season will need to adjust their itineraries, but plenty of other geyser-scapes and trails await just down the road.
A (Brief) History of Biscuit Basin’s Biscuits
- 1959 Hebgen Lake quake: Sapphire Pool erupted, scattering the biscuit-shaped silica nodules that gave the basin its name.
- 1991 eruption: Another burst sent mud and steam skyward, yet the basin’s other features, like Jewel Geyser, kept erupting every 7–10 minutes.
- July 23, 2024: The latest hydrothermal blast prompted the closure of the 0.6-mile loop boardwalk and all adjacent trails.
What You’re Missing (For Now)
- Sapphire Pool: Still one of Yellowstone’s most gorgeous deep-blue springs.
- Mustard Spring: A vivid yellow-green counterpoint to the sapphire hues.
- Jewel Geyser: Regular spurts of steam and water, roughly every 7–10 minutes.
Nearby Trails Still Open
If you’re itching for a hike, head to these trailheads (just avoid the fenced-off Biscuit boardwalk):
- Mystic Falls Trail (2.4 mi RT): Follow a mountain creek through conifers to a 70-ft cascade on the Little Firehole River.
- Summit Lake Trail (14.5 mi one-way): A Continental Divide jaunt with views over Upper Geyser Basin; Smoke Jumper Hot Springs awaits midway.
- Upper Geyser Basin: Home to Old Faithful and the densest collection of geysers on Earth.
Why It Matters
Yellowstone’s hydrothermal features, which are powered by magma just 3–8 miles underground, are a delicate plumbing network of boiling water and steam. When constrictions build enough pressure, they can erupt with little warning. Biscuit Basin’s closure is a reminder that even in “park mode,” Yellowstone can be unpredictable.
Safety First
- Stay on designated boardwalks (where they’re open).
- Never approach or touch hot springs or thermal mats.
- Keep at least 100 yards from bears and wildlife.
- Watch your step: the ground can be unstable near vents.
We’ll keep you posted on reopening plans. In the meantime, explore nearby trails and remember: Yellowstone’s magic comes with a healthy dose of respect and caution.
