The outdoorsy soul could not ask for a better city than Boulder, CO. It boasts over 300 miles of hiking and biking trails, along with 45,000 acres of untouched open spaces. If you’re looking for an easy hike that still offers stunning views of the surrounding area, take your Boulder RV rental over to the Flagstaff Nature Center, which gives easy access to the family-friendly Boy Scout Trail. Feeling a little more adventurous? Check out Eldorado Canyon. This magnificent area features towering sandstone cliffs studded with 500 rock climbing locations. Be sure to keep an eye out for the local wildlife, too. The mountains around Boulder hold everything from the relatively gentle mule deer and elk to black bears, coyotes and mountain lions! No view is like the last in Eldorado Canyon, either. The area is blanketed in Douglas firs, ponderosa pine savanna, prairie, and shrubland, so there’s something new to check out no matter where you go. Eldorado State Park offers opportunities for fishing, horseback riding, hiking, mountain biking and much, much more. Other parks to check out with your Boulder motorhome rental include Moraine Park, a gathering place for more than 3,000 elk and 800 bighorn sheep, and Golden Gate Canyon National Park, which is comprised of 12,000 acres of meadows and aspen forest. And of course, don’t miss out on the famous Rocky Mountain National Park. It’s the third most-visited national park in the country. And if you’re feeling up for a challenge, be sure to check out Boulder’s most popular trail, the Royal Arch Trail. It’s a pretty strenuous hike, but the trail’s massive namesake sandstone arch more than makes up for it. You can see the entire city of Boulder and beyond, framed beneath the rock. Other great trails around the city include the Canyon Loop Trail, which offers unmatched views of Boulder Canyon, Walter Ranch Loop, just west of Boulder, Wonderland Lake Loop Trail, in the foothills of North Boulder, and Mallory Cave Trail (note that the cave itself is closed several months of the year for the sake of its bats).
