Geyser Hill Loop

Overview

If you want maximum geysers for minimal effort, the Geyser Hill Loop delivers. This boardwalk circuit sits just across the Firehole River from Old Faithful and threads past a dense cluster of stars—Beehive, Giantess, Doublet Pool, the Lion Group—while a short spur climbs to Observation Point for a crowd-beating view of Old Faithful. Plan on about 2.5 miles total if you include the Observation Point spur (roughly 288 feet of gain). The boardwalk-only loop is shorter and essentially flat.

What You’ll See

This is classic Yellowstone hydrothermal country: hot springs, splashing geysers, and vividly colored thermophile mats. Beehive Geyser is a highlight—when it goes, it can fire a powerful column 130–190 feet for several minutes. Watch its “Indicator” (a small adjacent spouter): when it starts playing, Beehive may be imminent. From Observation Point, you’ll get a high, quiet vantage to watch Old Faithful erupt without the grandstand crowds.

Route and Logistics

Start from the Old Faithful Visitor Education Center area (large parking lots), circle past Old Faithful, cross the bridge toward Geyser Hill, then walk the loop clockwise or counterclockwise. Add the signed spur to Observation Point for that elevated view before dropping back to complete the circuit. Eruption predictions are posted at the visitor center—time your walk to catch Old Faithful or even Beehive.

Most of this outing is on wide boardwalks with gentle grades. The Observation Point spur is steeper, with switchbacks, and not wheelchair-accessible. Deeper in the basin, facilities thin out; plan restroom stops near the visitor center (there’s a composting toilet farther out by Morning Glory Pool if you’re extending your day).

Best Times to Hike

Crowds peak midday in summer. Go early morning for easier parking, softer light, cooler temps, and a more relaxed loop. Late October can be wonderfully quiet. Spring can bring lingering snow/ice on the hill to Observation Point, and June–July can be buggy. Roads to the Old Faithful area typically run mid‑April to mid‑November; in winter, access is by guided snowcoach only.

Safety and Etiquette

Thermal ground is thin with near‑boiling water below—stay on boardwalks and signed trails, and supervise kids closely. Expect periodic detours/closures in this area; follow posted signs. If Beehive or its Indicator is playing, position yourself upwind; the spray can spot camera lenses with silica. Wildlife does pass through: give animals space (at least 100 yards from bears; 25 yards from bison and elk), and never feed them. Pets are not allowed in thermal areas.

Extend or Compare

Have more time? The longer CDT + Observation Point + Upper Geyser Hill combo is about 6.0 miles with ~482 feet of gain. Or turn the day into a basin sampler and continue farther to features like Morning Glory Pool; ambitious hikers can connect beyond to Fairy Falls and Imperial Geyser.

Bottom line: it’s busy, but the density of world‑class geysers and the Observation Point vantage make this one of Yellowstone’s most rewarding short walks.
