What you should know
Reservation requirements: Most sites require advance booking during peak season (May-September). For Chatfield State Park Campground, one reviewer explained, "Without a reservation you put your name on a list that they start going through at 1pm to assign sites." Weekends typically fill months in advance at most Denver-area parks.
Highway noise: Some campgrounds experience significant traffic sounds. At St. Vrain State Park, a camper warned, "I-25. The interstate is so close as I type this I can hear in my travel trailer every truck, motorcycle, and car." Another advised to "Check the map of the campground and choose a spot far from the Interstate highway, it's closer than you think!"
Entry fee requirements: Daily access fees apply in addition to camping costs at many locations. At Cherry Creek State Park, one camper noted, "There is also an $11 day pass fee not included in your camping stay." Most state parks charge both a camping fee and park entrance fee.
Severe wind exposure: Limited tree cover at reservoir-based campgrounds creates wind issues. A Standley Lake camper mentioned, "Wind was pretty intense since we were in the middle of the field, make sure if you have a tent it is well tied in. Most of our stakes came out despite being hammered in."
Tips for camping with families
Playground access: On-site play areas available at several campgrounds. At Chief Hosa Campground, one visitor noted they "had a nice little store and playground." Another mentioned it's "child friendly" with "amazing" trails, though they noted "the sound of screaming children that pervades the campsite."
Beach activities: Swimming beaches at select locations for summer cooling. Bear Creek Lake Park offers "a beach, horse stables and ring, large lake to fish, clean bathrooms" according to one family. Another noted it has "lots to do in this little area-lakes, trails, horses."
Dog restrictions: Varying policies for pet owners across campgrounds. At Standley Lake, one camper noted "The campsites are very large. There's no hook ups for water, electric or dump sites although there are water spigots that can be used to fill fresh water." Dog owners should check individual park rules as some restrict off-leash areas.
Early entry timing: Plan morning arrivals to avoid entry delays. A Cherry Creek camper advised, "If you want to get into the Park, suggest you go EARLY, EARLY, EARLY in the day. Traffic backs up all the way from the Entrance on Parker Rd to the Entrance Booth on weekends and holidays. Plan on an hour OR MORE to just get to the booth."
Tips from RVers
Level site selection: Check maps carefully before selecting sites at mountain campgrounds. One RVer at Standley Lake reported, "We got site 47, which is labeled as an RV site, but it is NOT suitable for pop up campers. The site doesn't have even a hint of a levelable spot." Request specific site recommendations when making reservations.
Shower facilities: Pay showers common at most established campgrounds. A Chief Hosa camper noted, "They were quarter showers for 2 minutes of hot water, so basically less than $1 per shower, which is great." RVers without onboard showers should bring quarters for pay facilities.
Capacity restrictions: Size limits apply at several campgrounds. A Clear Creek RV Park visitor noted, "Must be an experienced driver to navigate the tight lots and roads." Most mountain campgrounds have length restrictions under 35 feet, while reservoir-based campgrounds typically accommodate larger RVs.
Dump station access: Limited availability at some locations. A Standley Lake camper noted "There's no hook ups for water, electric or dump sites although there are water spigots that can be used to fill fresh water." Plan dump station visits before arriving or when leaving these facilities.
