Cool Things to Do Near Denver in Summer: 4 High-Elevation Adventures to Beat the Heat
Let’s face it — August in Denver is hot. And while the sun might be great for patios, sometimes you just want to breathe mountain air and escape the heat.
The good news? Some of the coolest things to do near Denver in summer are less than an hour away — literally and figuratively. From high-alpine Jeep tours to icy lake swims and underground gold mine adventures, these day trips offer the perfect way to chill out without going far.
1. Take a High-Altitude Jeep Tour (You Drive!)
One of the best ways to cool off in summer? Go higher. Our Native Jeep Tours in Idaho Springs climb to over 12,000 feet, where temperatures drop and the views stretch for miles.
No crowded trailheads
No sweating through a hike
Just you, the mountain breeze, and a rugged Jeep you get to drive yourself
This is a fully guided experience — but you’re the one behind the wheel, following your guide through pine forests, alpine meadows, and panoramic ridgelines.

2. Cool Off Tubing in Golden’s Clear Creek
Nothing says “Colorado summer” like floating down a cold mountain stream — and Clear Creek in Golden is one of the best (and easiest) spots to do it. Just 30 minutes from Denver, this lively stretch of water is a go-to for tubing, wading, and cooling off fast. You can bring your own tube or rent one in town.
Water is cold even in August — perfect on a hot day
Fun for adults, teens, and adventurous families
There are riverside paths, grassy parks, and breweries nearby for post-float hangouts
Pro tip: Wear water shoes, avoid high-flow days, and always check local signage for safety updates.
3. Swim in a Cold, Clear Mountain Lake
There’s nothing more refreshing than dipping into a chilly alpine lake on a hot day — and Colorado has plenty within driving distance of Denver.
Here are a few cold-water favorites:
St. Mary’s Lake (near Idaho Springs) – A short hike takes you to a stunning glacial lake perfect for an icy plunge.
Echo Lake (off Mt. Blue Sky Scenic Byway) – Wading-friendly with shady picnic areas and high-altitude serenity.
Dillon Reservoir – Swim, paddleboard, or sunbathe at Marina Park in Dillon, about 1.5 hours from Denver.
Clear Creek (in Golden) – If lakes aren’t your thing, try tubing or wading close to town.
Tip: Even a 10-second dip in a mountain lake can cool you down for hours.
4. Go Underground at the Phoenix Gold Mine
If mountain air isn’t enough, head below ground. The Phoenix Gold Mine, located just above Idaho Springs, offers tours through real 19th-century mining tunnels — naturally cooled to around 50–55°F all year long.
Learn how gold was mined and hear wild stories from real miners
Try your luck panning for gold in the creek
Fun for kids, dog-friendly, and never too crowded
It’s the perfect way to stay cool while getting a dose of authentic Colorado history.
Don’t Just Survive the Heat — Escape It
Instead of hiding inside or melting on a sidewalk patio, escape to the mountains where the air is crisp, the lakes are icy, and the tours come with a side of alpine adventure.
Whether you’re looking for a unique day trip from Denver or just want to soak in those late-summer Colorado vibes without the heat, these experiences deliver.
