Daily high temperatures in the park often reach or exceed 95F (35C) and remain hot through sundown. Many trails have little to no shade. Avoid running during the hottest hours of the day (10 am to 6 pm), and carry and drink water throughout your visit.
Pets are prohibited on the trail or below the rim of Horseshoe Canyon.
Group size is limited to 20 people. Larger groups must arrange in advance to go with a ranger or split into smaller groups.
Horseshoe Canyon contains several intriguing rock art panels, including The Great Gallery
, which features remarkable life-sized figures and intricate designs. Other highlights include spring wildflowers, sheer sandstone walls and shady cottonwood groves. Visiting every rock art panel involves a round-trip run of seven miles, so a trip to Horseshoe Canyon usually requires a full day.
Be prepared for running on uneven terrain, over steep rocky areas and slogging through sand. The run to the "Great Gallery" is seven miles round-trip, requiring five hours or more. A steep descent of around 780 ft at the beginning of this run means a steep climb back up at the end of your run.
Cottonwood groves and many desert wildflowers can be found in the depths of Horseshoe Canyon.
