Timpanogos Cave National Monument opens 2026 season with guided tours
Timpanogos Cave reopened May 18 with guided tours only, turning a steep American Fork Canyon hike into a three-hour shoulder-season outing.
The cave door was back open in American Fork Canyon, but only for visitors who were ready to book a guided tour and earn the view with a steep climb. Timpanogos Cave National Monument opened its visitor center, caves and cave tours for the 2026 season on May 18, giving Utah travelers one of the clearest shoulder-season outings on the Wasatch Front.
Access to the cave system is not casual. Visitors must be on a cave tour to enter, and the only route in is a strenuous 1.5-mile paved trail that rises 1,092 feet to an elevation of 6,730 feet. The round-trip hike and cave tour together take about three hours, which makes this a half-day commitment rather than a quick stop. The cave itself stays around 45 degrees, a sharp contrast to the trail, where mid-summer temperatures can exceed 100 degrees.
The monument’s operating calendar showed daily cave tours and lantern tours on opening day, with tours typically running every 15 to 30 minutes throughout the day, seven days a week during the cave season. The standard cave tour lasts about 55 minutes. Historic Lantern Tours add a more old-school experience by letting visitors see the cave lit the way early explorers once did. Educational field trips are also offered from May through September, with applications opening every Nov. 1 for the next spring.
Planning matters here. Every person entering the cave must have a ticket, including infants, and strollers or other wheeled vehicles are not allowed on the cave trail. The cave tour season usually begins in May or June and runs through September or October, depending on snowfall, staffing, budget and construction, so the exact schedule can shift from year to year.
The site’s appeal runs deeper than the hiking challenge. Timpanogos Cave National Monument was created to preserve features of unusual scientific interest, including helictites, colorful formations, fault-controlled passages and alpine surroundings. Martin Hansen first discovered Hansen Cave in October 1887, James W. Gough and Frank Johnson found Timpanogos Cave in 1913, and Vearl Manwill rediscovered it on Aug. 14, 1921. Just 14 months later, President Warren G. Harding proclaimed the monument on Oct. 14, 1922.
For travelers driving in from the Wasatch Front, the trailhead sits in American Fork Canyon on Utah State Route 92, about 10 miles east of Interstate 15 and roughly 40 miles from Salt Lake City. With the season now open, Timpanogos Cave again offers something rare in a spring travel week: a mountain hike, a ranger-led cave tour and a history-rich underground stop in one trip.
