August in Colorado is a countdown. The days are still long and warm, the light stretches until nearly 8 PM, and yet the first day of school sits circled on the calendar in permanent marker. If you're scrambling to squeeze in a few more adventures, you're not alone — and you're probably also doing the math on what all those tickets cost.
Here's the good news: every outdoor activity for kids in Colorado on this list is included with a GetOut Colorado membership. One annual fee of $49.95 covers 82+ venues across the state, which means the hard part becomes choosing where to go — not whether you can afford it.
Big Outdoor Thrills for Colorado Families
1. Lakeside Amusement Park — Denver A genuine slice of history, open since 1908 and the oldest amusement park in Colorado still running in its original location. The Kiddies' Playland section is built for the under-8 crowd. Evening visits are magical when the Tower of Jewels lights come on.
2. Elitch Gardens — Denver Colorado's only combined theme and water park pairs six coasters with Island Kingdom, so you can ride in the morning and cool off by afternoon. Note that Elitch Gardens is available as a GetOut add-on venue rather than part of the base membership.
3. Fort Fun — Fort Collins An outdoor quarter-mile go-kart track, two full 18-hole mini golf courses, a giant slide, and seasonal bumper and paddle boats on the lake. It's the rare spot where a 6-year-old and a 15-year-old both find something they actually want to do.
4. Boondocks Food & Fun — Northglenn & Parker Go-karts, bumper boats, outdoor mini golf, and a ropes course. Two Front Range locations make it an easy weeknight outing rather than a full-day commitment.
Wildlife Encounters Under the Colorado Sun
5. Pueblo Zoo — Pueblo Twenty-five acres of outdoor exhibits with historic 1930s WPA stonework throughout, plus 400+ animals. Arrive at opening — the animals are more active in the cool morning hours, and so are your kids.
6. Rocky Mountain Wildlife Park — Pagosa Springs A quarter-mile gravel trail winds past rescued bears, elk, mountain lions, and foxes. The daily 3 PM feeding tour is the whole reason to go — a keeper walks the loop with you, animal by animal, at no extra charge. Summer horseback trail rides run through the end of August. Bring hats and water; there's very little shade.
7. Colorado Gators Reptile Park — Mosca Alligators. In the San Luis Valley. At 7,500 feet. A geothermal well keeps this improbable 80-acre farm running year-round, and guests get free catch-and-release fishing. It's the kind of place kids talk about for years.
Catch a Game Outside Before Summer Ends
8. Colorado Rockies — Coors Field, Denver Outdoor baseball with a mountain skyline beyond the outfield. August home games are prime — warm evenings, no jacket required.
9. Colorado Rapids — DICK'S Sporting Goods Park, Commerce City MLS soccer hits its stride in late summer. Shorter than a baseball game, which matters if your youngest has a two-hour attention span.
10. Colorado National Speedway — Dacono Saturday night stock car racing on a 3/8-mile asphalt oval, with more than 12 divisions competing spring through fall. Loud, fast, and completely different from anything else on this list. Pack ear protection for little ones.
Hands-On Adventure for Older Kids and Teens
11. Altitude Outdoor Adventures — Cedaredge Pontoon boats, kayaks, paddleboards, and e-bikes on Grand Mesa, the world's largest flat-top mountain with roughly 300 lakes. The summer season closes no later than September 30, so August is your last real window.
12. ColorSplash Paintball Park — Pueblo Five acres of open outdoor terrain with forts, hills, and valleys, plus low-impact options like gellyball and combat archery for younger players. If you're hosting an end-of-summer birthday for a 12-year-old, this solves it.
13. Colorado Journey Miniature Golf — Littleton Two 18-hole outdoor courses themed around Colorado landmarks — putt through the Cripple Creek Mine, past Mesa Verde, and over the Royal Gorge. A geography lesson disguised as putt-putt.
Outdoor Learning That Doesn't Feel Like School
14. Colorado Railroad Museum — Golden Nearly 20 acres of outdoor rail yard between North and South Table Mountains, with locomotives kids can climb aboard and seasonal train rides. Sneaky-educational and genuinely fun.
15. Pueblo Weisbrod Aircraft Museum — Pueblo Roughly 40 aircraft across two hangars and a large outdoor display area, including a B-29 Superfortress. Kids get up close to fighter jets and military vehicles, and the air-conditioned gift shop is a welcome break from the August heat.
How to Do All of This for Under $50
Run the numbers. One Rockies game for a family of four plus a single amusement park visit already costs more than an entire year of GetOut. Everything after that is effectively free.
The GetOut app makes it simple: browse venues near you, pick one, and show your phone at the counter. No coupon printing, no advance planning, no reservation anxiety. With a 4.6 rating and more than 300,000 members nationwide, it's a system families already trust.
A few August-specific tips: start early to beat the afternoon heat, watch the 2–4 PM thunderstorm window that's typical along the Front Range, and reapply sunscreen more often than you think you need to — UV exposure at Colorado's elevation is significantly stronger than at sea level.
Start Your August Adventure
Summer isn't over yet. Grab your GetOut Colorado membership and turn the last few weeks into the ones your kids remember.
Traveling or relocating this fall? GetOut runs in other states too — a Utah membership opens up mountain-town adventures and family entertainment centers across the Wasatch Front, while an Arizona membership covers desert attractions and water parks that stay fun long after Colorado cools down.
