All Campground Reservations are 4 Days / 3 Nights.
Day 0 (the day before your Campground Reservation arrival date): Arrive in the area. Drive to a hotel near the trailhead (Peach Springs, Seligman, Kingman) and get a good night's sleep to get an early start the next morning.
Day 1: Drive to trailhead, hike in, set up camp, explore the creek and Campground.
Day 2: Rest, relax, enjoy, explore! A good day for the lower waterfalls (Havasu, Mooney, Beaver)
Day 3: Rest, relax, enjoy, explore! A good day for the upper waterfalls (Fiftyfoot, Little Navajo, Havasu)
Day 4 (the day of your Campground Reservation departure date): Hike out and drive to a hotel near the trailhead (Peach Springs, Seligman, Kingman) and rest, relax, recover. This means you won't have to stress about needing to rush back anywhere that same day.
Day 5 (the day after your Campground Reservation departure date): Drive/fly back home - or stay in the area and explore even more! There is plenty to see and do in the Grand Canyon region and on the way to/from the nearest major airports in Las Vegas (Grand Canyon West, Hoover Dam, Lake Mead) and Phoenix (Grand Canyon National Park South Rim, Antelope Canyon, Horseshoe Bend, Page, Glen Canyon Dam, Lake Powell, Flagstaff, Humphreys Peak, Oak Creek Canyon, Sedona, Prescott, Scottsdale, etc).
