Chatfield State Park, Colorado

Denver's own Chatfield Reservoir doubles as both an expansive reservoir and abundant wildlife refuge, while, simultaneously, acting as a natural water park. The reservoir, itself, provides 1,423-acre surface area lake, fed by the South Platte River and two sister creeks, one being beautiful Plum Creek. Kayaks, paddleboards, jet skis, boats, and canoes can be taken out on this man-made body of water, where water goers can appreciate the beautiful rolling foothills that sit just a stone’s throw away from the Denver Metro Area. And yes: you can string-out your beach towel and get some rays atop one of the park’s reservoir-hugged swimming beaches.

Hikes and bikers can enjoy miles of trails that comb through this nearly 4,000-acre state park. Avid bird watchers, don’t forget your binoculars! This park’s full of resident and migratory song and water birds.

A dizzying 204 campsites populate the entire park, ranging from primitive, barebones sites to ones with full hookups—that also boast available Wifi. Four group picnic areas can also be reserved and, better yet, most campsites are pet-friendly, to boot. Campers can even take advantage of a laundromat located just by the washing stations (that have hot water!) and dumping stations, all walking distance from any one site. Hungry? Check out the park’s own floating restaurant, Seagull's Restaurant, to take a break from the usual campfire fare.

Outside of the dead of winter, this park should sit high on any camper’s must-hit list. Autumn bathes the thick oak groves with breathtaking yellows, reds, and oranges, while the warmer summer and spring months allows nearly endless water sporting opportunities.
