Castle Rock sits on I-25 about 30 miles south of downtown Denver, roughly halfway to Colorado Springs. For RV trips it works as a quieter base with quick access to both cities, and it is close to Larkspur, home of the Colorado Renaissance Festival on summer weekends.
Why families pick this stretch of I-25
Traffic is lighter than in the Denver metro, and there is open country with views of the foothills. You can reach Denver attractions in under an hour and Colorado Springs in about 45 minutes. That makes it a practical middle base for a week that mixes city days with time at camp.
Nearby outdoor time
- Rock Park, the butte the town is named for, with a short climb to views over the valley.
- Castlewood Canyon State Park near Franktown, a day-use park with canyon trails and the remains of an old dam.
- Larkspur, a few miles south, for the Renaissance Festival in season and private campgrounds.
Supplies and errands
Castle Rock has full-size grocery stores, fuel stations that fit larger rigs, and an outlet mall right off the interstate. If you book grocery stocking through RVRents, a coordinator places the order with a local provider and confirms the delivery window with your campground first.
When to go
Summer is the busiest season, especially around festival weekends in Larkspur. Spring and fall bring cool nights at this elevation, which is above Denver's, so pack layers. Summer afternoon thunderstorms are common along the Palmer Divide south of town.
