This 2.3 mile loop trail leads you across the Firehole River, through a forest-fire burned area, and up to a breathtaking overlook of the Upper Geyser Basin and perhaps the best place to view Old Faithful
erupt. The trip down leads you around Geyser Hill, past many fascinating geysers and hot springs.
Features: Geyser — Hot Spring — Views
Short trail is packed with interesting hot springs and geysers. Although the climb to Observation Point is tough for some, the view is spectacular & seeing Old Faithful
erupt from the top is fun!
Dogs: No Dogs
Check at the Visitor Center for the next predicted eruption of Old Faithful
and plan your visit so you arrive at Observation Point before it erupts. Many believe it is the best place to enjoy this wonder of nature.
From the Visitor Center, the Geyser Hill Trail
circles east of Old Faithful
Geyser (on your left) along a walkway, passes Old Faithful
Lodge (on your right), then forks right and drops to a crossing of the Firehole River at the .3-mile mark. Immediately after crossing the Firehole, turn right and begin following the Observation Point Trail
(unpaved) as it climbs 230 feet through a partially burned lodgepole pine forest.
At the .6-mile mark, near the top of the hill, the trail divides.Turn right and follow the loop trail as it switchbacks up the plateau rhyolite to Observation Point. The view from the point is magnificent! The entire Upper Geyser Basin spreads out before you. The 150 active geysers that lie here comprise more than 25% of the world's total and include some of the largest and most predictable geysers.
Geyser was named by the 1870 Washburn Expedition who wrote: "we emerged from the woods opposite Old Faithful
just as it was giving vent to its internal motions. From that time our spirits rose and all our personal woes and sufferings were forgotten." For over 145 years, Old Faithful
's regular, predictable eruptions have had a similar effect on millions of Yellowstone visitors. Other geysers with eruptions large enough to identify from the point include Castle, Beehive, and Giantess, all of which were also named by the Washburn Expedition.
is the most frequent and predictable large geyser in Yellowstone and richly deserves its fame. It erupts to between 106 and 184 feet (average height is 130 feet). Each eruption lasts between 1.5 to 5 minutes. The interval between eruptions is 60 to 110 minutes.
As you wait for the geyser to erupt, contemplate another of nature's forces. On September 7, 1988, wild fire attacked this area with a vengeance. Fanned by wind gusts of up to 70 mph, a massive wall of fire descended on Old Faithful
from Madison Plateau to the southwest. It roared across this large valley, jumped the Firehole and climbed this ridge. There was nothing man could do to stop it. In fact, it took a herculean effort and a lot of luck to save the Old Faithful Inn
After Old Faithful
erupts, continue west along the trail as it loops back down to the main trail. Turn right and follow it another 0.3 miles to Solitary Geyser. It has an interesting history. Prior to 1915 it was an infrequently visited hot spring. That year water from the spring began being piped down to fill a commercial swimming pool. As the water level lowered, the water pressure dropped. This in turn caused the superheated water below to flash into steam and the spring was transformed into a geyser. Today it continues to erupt to a height of 6 feet every 5 to 7 minutes.
From Solitary Geyser the trail continues to a junction with the Geyser Hill Trail
at the 1.7-mile mark. Turn left on this paved trail and follow it past beautiful deep blue Doublet Pool (on the right) to Giantess Geyser. Giantess is one of the largest and most powerful geysers in the park. Its infrequent eruptions explode from its large pool to a height of 200 feet. Its duration lasts many hours and progresses from a water phase to a powerful steam phase. During eruptions the seismograph in the visitor center can detect small tremors in the ground and the roar of the steam can be heard more than a mile away. The Washburn Expedition who named this magnificent feature exclaimed, "All we had previously witnessed seemed tame in comparison with the perfect grandeur and beauty of this fine display . . . This geyser we named the Giantess."
The Geyser Hill Trail
you are following returns you to the bridge used earlier to cross the Firehole River. From there it's a short distance back to the Visitor Center. However, there are miles of additional boardwalks and trails in the Old Faithful
area. The extra time you take to explore them will be richly rewarded.

The 1988 fires opened the forest canopy along this trail up to Observation Point allowing more sunlight to reach the forest floor. The rich understory includes pretty, pink, sticky geranium and wild rose, delicate blue harebell, holly-like leaved Oregon grape, deep pink fireweed, and intricate purple monkshood. Look carefully, you may even spot some tasty wild raspberries!
