Encompassing nearly 2 million acres, this national forest—named for the river that runs through it—features a mix of dense woodlands, mountains, and even high desert. Places of particular interest include the Silver Thread Scenic Byway, known for its beautiful scenery, and the Wheeler Geologic Area, a rugged hiking area offering views of ancient geologic formations. Popular activities in the forest include hiking, fishing, rafting, off-highway vehicle (OHV) riding, rock climbing, winter sports, and camping. There are 33 campgrounds and around 651 campsites in the forest, most of which have potable water and vault toilets.

• Best for rafters: Palisade Campground has direct access to the Rio Grande.
• Best for nature photographers: high in the mountains, Zapata Falls offers epic views of the surrounding forest.
• Best for rock climbers: Penitente Canyon Campground gives you easy access to around 300 sport-climbing routes. 

1. The majority of campgrounds in the Rio Grande National Forest are available on a first-come, first-served basis. Arrive late morning when others are packing out for the best selection.
2. Eight of the campgrounds have reservable campsites. These are released at 8am Mountain Time, six months in advance. If you're trying to book a cabin or popular spot, be ready to book online right when it becomes available.
3. Choose harder-to-reach campgrounds for the best chances of getting a site. Campgrounds closer to cities fill up faster.
4. Consider coming mid-week if your schedule permits. Weekends can get busy, particularly in the summertime, but if you can come on a Wednesday or Thursday you’ll have more choices.

The best time to visit the Rio Grande National Forest depends on your interests, but it’s at its most popular in the warm summer months when kids are out of school. May and September are good alternatives for camping if you want nice weather without the crowds. Fishing season runs from June through October, though plenty of people come for ice fishing in the colder winter months. Other popular winter activities include sledding, skiing, snowmobiling, and snowshoes.

• Make sure to download offline maps before heading out. Phone and internet service is not always reliable outside of urban areas.
• Forest fires can be an issue in Colorado from late spring through early autumn. Make sure to check the Rio Grande National Forest website for details on closures or campfire bans before you take off.
• Dogs are allowed in the forest, but must be kept leashed in campgrounds and must be responsive to voice commands when out on trails.
• Check for snow-related road closures and avalanche warnings before you head out. Also remember to pack chains with you if there’s any chance you might find yourself in a blizzard.
