The San Francisco Peaks with all the forest and meadow landscape is a natural playground for kids. Flagstaff, in general, is one big playground for children and adults alike. When you arrive at a Flagstaff hotel with children, the staff know you're going to be looking for things to keep them busy and they're usually quite helpful. Some accommodations are located near trailheads and offer easy access hiking or biking. Most also supply their guests with free internet; many of the hotels in Flagstaff have pools where you can attempt to tire out the children if that long hike didn't do the trick. Getting kids to tire out before you do isn't easy; we always end up exhausted in a deck chair, but it's good fun to try!
If you base your stay out of Downtown Flagstaff, you are within easy striking distance of festivals and activities at Wheeler Park on weekends as well as nearly every type of dining option. Family-friendly hotels are typically bigger with more space to spread out; double or connected suites, even suites with a separate family room, and even vacation homes. At family-friendly hotels, a complimentary breakfast is often offered, which hopefully makes getting the whole family ready in the morning a little bit easier.
