10 Best Day Trips in Denver (Costs & Tips, 2026)

Trail Ridge Road climbs above 12,000 feet inside the park, the highest continuous paved highway in the country, and it's genuinely possible to see elk grazing roadside within the first ten minutes of entering. Thirty dollars for a day pass, about 90 minutes from Denver, and the park's own timed-entry reservation system runs during peak summer months, so check before driving up.

Garden of the Gods costs nothing to walk through and delivers red sandstone spires that rival any national park's marquee formations, which pairs naturally with a paid drive or cog railway ride to the 14,115-foot summit of Pikes Peak nearby. Free for the garden; the mountain's highway toll runs $18 per adult, or considerably more for the railway. About an hour south of Denver.

Pearl Street's pedestrian mall alone justifies the short drive, but the real draw is how directly the Flatirons rise up right behind the University of Colorado campus, making the mountains feel like part of the town rather than a separate destination. Ten dollars covers parking for the day; Boulder itself is barely 30 minutes from downtown Denver.

This former gold-rush boomtown now runs mostly on its geothermal hot springs, with the historic Indian Hot Springs' cave pools and outdoor mineral baths drawing day-trippers up I-70 as much as the mining history does. Around $40 for hot springs access; the town itself costs nothing to wander, about 45 minutes west of Denver.

An entire Victorian-era silver-mining town survives here almost intact, and the narrow-gauge Georgetown Loop Railroad still climbs the same steep grade its 1880s builders engineered specifically to gain elevation without switchbacks. About $25 for the train ride, free to just walk the historic downtown, an hour west of Denver on I-70.

Elk wander the streets and golf courses here often enough in fall that the town runs its own dedicated elk-jam traffic advisories, a strange but genuine reason to visit even before factoring in that this is the main gateway into Rocky Mountain National Park next door. About $20 for a meal and parking in town; the elk-watching itself costs nothing.

Two former gold-rush towns sit side by side less than an hour from Denver, one lined with legal casinos, the other holding onto genuine 1870s brick storefronts and an opera house that's hosted performers since 1878. Budget varies wildly with the casinos; the historic walking tour itself is free, and it's the closest genuinely different-feeling town on this whole list.

Coors has brewed here since 1873, and the free brewery tour still walks through a working production facility rather than a sanitized visitor-center version of one — pair it with the Colorado School of Mines campus and Clear Creek's whitewater park, both a five-minute walk away. Free for the tour itself; about $20 covers a casual lunch. Barely 20 minutes from downtown Denver.

Ski lifts keep running through summer here, hauling mountain bikers and hikers up to alpine terrain most day-trippers would otherwise need a full hike to reach, and the town's Victorian Main Street stays just as walkable in July as it is in January. Around $35 for a lift ticket; about 100 minutes from Denver over Loveland Pass or through the Eisenhower Tunnel.

The alpine slide here — a real bobsled-style track down the mountain on a wheeled cart, not a metaphor — runs all summer and remains one of the more purely fun things on this entire list regardless of age. About $25 for slide tickets, roughly 90 minutes from Denver through the Moffat Tunnel corridor via US-40 over Berthoud Pass.
