Glenwood Springs Attractions: Hot Springs, Cave Tours, Scenic Trails, and Hanging Lake

Glenwood Springs sits at 5,761 feet, where the Roaring Fork River meets the Colorado. Founder Isaac Cooper renamed the settlement, first called Defiance, after Glenwood, Iowa, the hometown his wife Sarah missed. The Ute people already knew the main spring as Yampah, or “Big Medicine,” when Walter Devereux and his brothers bought it in 1886.

Steam rooms, mineral pools, limestone caverns, and cliff-top trails all sit within a short drive of downtown Glenwood Springs. Several of them overlap, though, and the differences matter more than the names suggest.

Hot Springs: The Grand Pool or the Riverside Pools?

Glenwood’s two riverside resorts draw on different sources and feel very different in the water.

Glenwood Hot Springs Pool

On July 4, 1888, Glenwood Hot Springs Pool welcomed its first bathers. The Yampah spring still pours out roughly 3.5 million gallons a day at 122°F. The Grand Pool measures 405 by 100 feet and sits at 90 to 93 degrees, while the Therapy Pool reaches 104. Next door, the historic Stone Bath House once held 42 sunken Roman vapor baths. Today it houses the 16-room Hotel 1888. The five Yampah Mineral Baths add waterfall features and two cool-water pools at no extra cost, though they turn adults-only at 5 p.m. Day passes run $42 to $60 for adults and teens and allow re-entry all day.

Iron Mountain Hot Springs

Downstream on the Colorado, Iron Mountain Hot Springs lines the riverbank with 16 original geothermal pools at roughly 98 to 108 degrees. General Access costs $43 to $75 and includes a Family Zone with its own mineral pool and jetted spa. Adults 21 and older can choose an All-Access pass, from $75 to $150. It adds 12 WorldSprings pools and a Sauna Summit with four saunas and a steam room. The first bathhouse on this stretch of river went up in 1897, and the current resort reopened the site in 2015.

Which Pool Fits?

  • Swimmers and families with little ones tend to prefer the Grand Pool’s open water.
  • Bathers who like hopping between small, hot pools lean toward Iron Mountain’s terraces.
  • Children under 5 can’t enter Iron Mountain’s geothermal pools, so they stick to its Family Zone.
  • Spontaneous visitors do best at the Hot Springs Pool, which needs no reservation.

Underground: Hot Steam or Cool Limestone?

The town’s two cave experiences could hardly feel more different.

Yampah Vapor Caves

Beneath Yampah Spa & Vapor Caves on 6th Street, three adjoining rock chambers sit over a 125-degree spring that flows through the floor. The steam keeps the air between 110 and 113 degrees, so guests take short 10- to 12-minute sessions. Ute people used the caves for centuries, and the present spa building opened to the public in 1893.

  • Every visit requires a reservation, and booking opens three months out.
  • Guests need to be 13 or older, and anyone under 18 must have an adult nearby.
  • For $65, the “Cave & Soak” package pairs a 30-minute mineral bath with two hours of total cave access.

Glenwood Caverns

High on Iron Mountain, the limestone rooms of Glenwood Caverns Adventure Park stay near 52 degrees all year. Charles W. Darrow opened the Fairy Caves to the public in 1895 and wired them for electric light two years later. The caves closed in 1917, then remained dark until Steve and Jeanne Beckley reopened them in 1999.

  • Lasting about 40 minutes, the Historic Fairy Caves tour follows the original routes that early explorers used.
  • Farther underground, King’s Row descends 120 stairs to a chamber the park calls Colorado’s most decorated cave room.
  • Tighter spaces await on the Wild Cave Tour, which squeezes through gaps as narrow as 18 inches. It requires a separate reservation, costs $90 with the gondola, and welcomes ages 10 and up.

Published summer online rates start at $52.99 for the gondola and one standard cave tour. In 2023, the federal government named the caverns and Iron Mountain Hot Springs a National Natural Landmark.

Up High: The Cliff Edge Above Town

The summit attractions suit thrill seekers and anyone short on time, while the trails reward hikers who want history or scenery underfoot.

Iron Mountain’s Cliff Edge

From the base on Two Rivers Plaza Road, the Glenwood Gondola lifts visitors to Glenwood Caverns Adventure Park in about five minutes. Up top, the Giant Canyon Swing launches four people at a time from a cliff about 1,300 feet above the Colorado River, reaching 50 mph. Crystal Tower takes riders through a passage into the Crystal Grotto and then drops them in a freefall. Riders need to be at least 48 inches tall. The swing operates from spring through October, while the Alpine Coaster and cave tours continue all winter. A $79.99 Funday ticket covers both standard cave tours and the thrill attractions.

Two Climbs Close to Downtown

From 12th Street and Bennett Avenue, the Doc Holliday Trail climbs steeply to Linwood Cemetery in under a mile round trip. On the west edge of town, the Jeanne Golay Trail starts on West 9th Street near Yampah High School. It follows the road of a former ski area. Glenwood skied these slopes from 1941 to 1952, and the routes now run 2 to 7 miles. Private land caps the summit.

Hanging Lake, the Big Hike

East of town, Hanging Lake sits on a cliff shelf in Glenwood Canyon, a 12-mile gorge on the Interstate 70 drive from Denver. At 7,323 feet, waterfalls pour over travertine ledges to feed the lake. Just beyond the lake, Spouting Rock lets hikers walk behind a waterfall bursting from the limestone.

  • Each hiker must hold a timed permit, currently $12, which includes parking for a three-hour window.
  • The round trip takes about three hours, and there’s no drinking water on the hike.
  • Eastbound traffic uses I-70 Exit 125, while anyone heading west loops back from Exit 121.
  • No shuttle serves the trailhead, and the rules bar taxis and app-based cars from dropping off or picking up hikers.
  • A private vehicle may drop you off, but any pickup has to leave the lot by 4 p.m. The lot also turns away vehicles longer than 25 feet.
  • Dogs, swimming, and wading are off-limits.

Putting the Choices Together

The town has enough variety to fill several days, but not every attraction needs a full afternoon. The Doc Holliday Trail makes a shorter outing, while Hanging Lake calls for more preparation and a reserved hiking window. Glenwood Caverns pairs guided underground exploration with seasonal thrills, and the riverside hot springs give visitors a place to unwind afterward.

Check the current admission rules, leave room for weather changes, and choose activities that match your group’s interests and comfort with the altitude.
