Just 45 minutes from Denver, this hidden gem near Franktown delivers winding trails, canyon-carved views, and even a crumbling old dam that nature is slowly reclaiming.

From peaceful pine forests to dramatic rock faces and bubbling creeks, Castlewood feels like a choose-your-own-adventure storybook. Whether you’re chasing waterfalls, marveling at history, or just ready for a scenic stroll, this park invites you to slow down, look around, and soak it all in.

What We Love
The Castlewood Dam Ruins
One of the park’s most surprising features is its broken heart: the remnants of the Castlewood Dam, which dramatically collapsed in 1933. Today, moss-covered concrete walls and twisted rebar remain as eerie, photogenic reminders of the past—and they’re easy to explore just off the Creek Bottom Trail.
Waterfalls in the High Plains
Yes, waterfalls—plural! After heavy rains or during spring melt, Cherry Creek tumbles over dark volcanic rock in a series of gentle cascades that feel plucked from a postcard. You’ll hear them before you see them.

Hiker’s Playground
Castlewood has trails for every energy level. Try the Rim Rock Trail for wide-angle views, or the Inner Canyon Trail if you’re feeling bold and don’t mind a little rock hopping. Many trails loop together, so you can tailor your outing from quick stroll to half-day trek.
Birds, Lizards, and Lucky Bobcats
Bring the binoculars. This state park is a hotspot for golden eagles, canyon wrens, and sunbathing lizards. Early risers might even spot a bobcat or fox—though they’re shy and quick to vanish.
Perfect Picnic Spots
Tables are scattered near the visitor center and along scenic overlooks. Bring a packed lunch and a camp chair—you’ll want to linger.
Atmosphere & Setting
Castlewood Canyon feels like Colorado’s version of a secret desert oasis. Tall Ponderosa pines line the ridges, while sandstone cliffs create dramatic shadows across the canyon floor. The air smells of juniper and warm rock, and in the quieter sections, the only sounds are wind and birdsong. Trails meander beside streams and through scrubby meadows dotted with cactus blooms and wildflowers. It’s a peaceful, gently rugged vibe—like stepping into an old western painting that suddenly turns into a nature documentary.
Value (Is It Worth It?)
Absolutely. A $10 day-use fee gets you access to 13 miles of trails, epic photo ops, and a full dose of nature therapy. Expect to spend 2–4 hours here, depending on your route. It’s perfect for solo hikers, couples, active retirees, and families with kids who love climbing rocks and spotting lizards. There’s no flashy visitor center show or zip line thrill—just good, honest outdoorsy fun.
