The 4.6-Mile Colorado Trail With Secret Caves, Waterfalls, And Huge Cliffside Views

A dam built in 1890 burst in 1933, and its flood rushed down Cherry Creek all the way toward Denver. The broken stone walls are still standing in a quiet canyon today.

Better yet, a hiking loop takes you right past them.

That alone would earn a spot on my weekend list. But this Colorado trail also climbs a rocky rim with views reaching toward Pikes Peak.

Then it drops down to a creek bottom where caves hide in the cliffs.

I like how one walk packs so much into under five miles. You get history, geology, and wildlife along the loop, while a separate trail leads to the park’s waterfall.

I can’t imagine a better way to spend a cool spring or fall morning outdoors.

So where is this trail, and what should you know before lacing up?

One Loop Gives You Two Completely Different Hikes

Most trails pick a lane. The Rimrock to Creek Bottom Loop at Castlewood Canyon State Park refuses to choose.

The loop runs about 4 miles through a canyon cut by Cherry Creek. Half the time you’re up high on rocky ledges, and half the time you’re down by the water.

That mix is what makes it special. Up top, the views stretch wide across open land.

Down low, the trail feels shady, cozy, and close to the creek.

Expect real effort along the way. The loop has steep climbs and noticeable elevation changes, with sections officially rated moderate to difficult.

Good shoes matter here. Some sections ask you to step over rocks and roots, and a few spots get a little scrambly.

The park covers 2,628 acres of canyon country. Its cliffs rise as high as 60 feet, which keeps the scenery changing around nearly every bend.

Plan for a few hours so you aren’t rushing. Snack breaks, photo stops, and staring at rocks all take time, and honestly, that’s the point.

Up On The Rim, The Whole Front Range Shows Off

Pikes Peak makes a guest appearance on this stretch. On clear days, the Rimrock Trail lets you spot it far off on the horizon.

This section follows the edge of the canyon. Below you, Cherry Creek twists through the trees like someone dropped a ribbon.

The views reach out toward the Front Range too. It’s a big, sweeping look at Colorado that usually takes a long mountain drive to earn.

Watch your footing, though. The rim is rocky, and you’ll want your eyes on the trail more than your phone.

Sun is a real factor up here. The rim offers very little shade, so hot afternoons can feel brutal fast.

Bring more water than you think you need. A hat and sunscreen are smart picks too, especially in summer.

Early mornings are a great time for this part. The light is softer, the air is cooler, and the photos look extra sharp.

Photographers love these sandstone cliffs for good reason. Layer after layer of rock stacks up, and each layer seems to glow a slightly different color.

Those Cliffside Caves Are Calling Your Name

Caves in a plains-side park sound made up. Yet Castlewood Canyon has several tucked into its rocky walls.

The Creek Bottom Trail gives you views of these cliffside openings as you hike. They pop up in the rock like little secret doorways.

Want a closer look? A short Cave Trail runs about one-eighth of a mile one way, and it links up with other routes.

One cave is described as a large crack in the rock. That crack leads back into a bigger chamber, which feels pretty dramatic for such a quick detour.

Kids usually find this part the most exciting. Adults do too, even if they pretend they’re just there for the exercise.

Take it slow around the rocks. Surfaces can be uneven, and a flashlight or phone light helps you peek inside safely.

Respect the space while you explore. Leave everything as you found it so the next hiker gets the same thrill.

Adding the Cave Trail barely changes your total distance. For a payoff this cool, that’s a pretty great trade.

A Waterfall Rewards Anyone Who Times It Right

Rain is your secret weapon here. After a wet stretch, Cherry Creek Falls turns from cute to seriously impressive.

The falls drop about 20 feet over the rocks. That’s not giant, but it feels like a big reward in a canyon this close to the plains.

Short on energy? An easy hike of roughly 10 minutes from a trailhead gets you there.

That makes the waterfall a handy stop for younger kids. Grandparents can usually join the fun without much trouble too.

Water levels change with the seasons. Dry spells can shrink the flow, so check recent conditions if the falls are your main goal.

Spring often brings the best show. Melting snow and rain give Cherry Creek more push, and the surrounding plants turn green.

Near the falls, the creek invites a closer look. Families often splash in the shallow spots on warm days, so pack a towel just in case.

Keep an eye on slick rocks. Wet stone is slippery, and nobody wants a soggy ride home with a bruised ego.

A Burst Dam Left Behind Some Seriously Wild Ruins

Back in 1890, builders finished a stone dam across Cherry Creek. Farmers wanted water for their crops, and the dam held it back for decades.

Then 1933 arrived. The dam burst, and a huge wave of water rushed toward Denver.

The ruins still stand today in Castlewood Canyon State Park. Huge chunks of stone wall remain on both sides of the creek.

Seeing them in person is honestly a little jaw-dropping. It’s hard to picture the force needed to break something that solid.

Trails let you view the old dam from different angles. You can look down from above or get close from the creek level.

Signs nearby share more of the story. Reading them turns a simple walk into a mini history lesson.

The Visitor Center shows a film about the dam and the flood. Watching it before your hike makes the ruins feel even more real.

Bring curious kids here. Few places in Colorado let them stand next to a piece of history this dramatic and this big.

Somebody Really Did Build A Home Out Here

Concrete in 1898 sounds oddly modern. But that’s exactly what the Lucas family used for their house in this canyon.

The remains of the Lucas Homestead still sit in the park today. Crumbling walls give you a glimpse of what ranch life looked like long ago.

Life out here wasn’t easy. Families depended on the land, the weather, and plenty of hard work to get by.

Standing near these walls helps that history click. You start noticing how far the nearest town must have felt back then.

The homestead ruins make a nice break on a long day. They also give kids something to explore that isn’t another rock.

Please don’t climb on the old walls. They’re fragile, and the park wants them standing for future visitors too.

Pair this stop with the dam ruins for a full history tour. Together they show how people tried to make a living in this rugged spot.

It’s a quiet, thoughtful part of the park. Somehow it makes the cliffs and creek feel even more meaningful.

Look Up, Because The Vultures Are Circling

Turkey vultures run the summer sky here. Large groups settle into the canyon during the warm months, turning it into a birding favorite.

Watching them glide is oddly relaxing. They barely flap, riding warm air above the cliffs for long stretches.

The bird list doesn’t stop there. Birders come for the variety, and spring brings plenty of songs along the trail.

Bigger animals live here too. The park is home to deer, elk, bobcats, and even black bears.

Early mornings and weekdays give you better odds of spotting wildlife. The trails are often quieter then, and animals tend to be more active.

Keep your distance from anything wild. A zoom lens or binoculars will get you closer than your feet ever should.

Snakes deserve attention as well. Rattlesnakes live in this area, so stay on the trail and watch where you step.

Some cliffs may close for part of the year to protect nesting raptors. It’s a small trade so the birds can raise their young in peace.

Know These Details Before You Hit The Trailhead

Getting there is simple. Castlewood Canyon State Park sits at 2989 S State Highway 83, Franktown, CO 80116.

It’s a day-use park, so no overnight camping. Gates open around sunrise, and the park closes around sunset.

Inbound gates shut one hour before closing time. Show up late, and you might be stuck admiring the canyon from the road.

Every vehicle needs a daily entrance pass. Walk-ins and bike riders pay a smaller per-person fee.

Leashed dogs are welcome on most trails. They’re not allowed on the East Canyon Preservation Trail, so plan your route with that in mind.

Bikes stay off the hiking trails. That keeps the paths calmer for everyone sharing them.

The park has separate east and west areas with different entrances. The west side is more rugged, while the east side has the Visitor Center and paved paths.

Spring and fall offer the most comfortable weather. Summer works too, but start early and pack plenty of water for those sunny stretches.

Save Energy For A Picnic When The Loop Is Done

Finishing the loop earns you a sandwich. Luckily, the park makes that part easy.

More than 30 family picnic sites are spread around the grounds. They’re first-come, first-served, so grab one early on busy days.

Bigger groups have choices too. Group picnic areas, covered shelters, and an amphitheater can be reserved for gatherings.

The Visitor Center is worth a stop before or after your hike. Restrooms, drinking water, and helpful signs make it a solid home base.

Need a gentler option for part of the crew? The paved Canyon View Nature Trail is ADA accessible, with lovely views for strollers and wheelchairs.

That means nobody gets left behind. One group can tackle the full loop while others enjoy the easier path.

In 2020, the park became a Leave No Trace Gold Standard site. Pack out your trash, stay on trail, and help keep this Colorado treasure looking great.

By the end, you’ll have seen caves, falls, cliffs, and ruins. Not bad for a single afternoon and one very happy pair of tired legs.
