The Arch Rock Trailhead is in the Twin Tanks Parking Lot. The trail looks like a lollipop; the route heads in a straight line for .6-miles from the parking lot to the east, where it becomes a short loop. Hikers can take the loop in either direction, but hiking it counterclockwise is recommended because it is easier to spot the namesake arch from that direct. The loop is a short .2-miles and leads hikers back to the straightaway trail to the parking lot.
The arch is roughly .1-mile into the loop section and is a popular photography spot. The loop also has educational wayside signs along the trail describing the unique geology and characteristics in the area. The first part of the trail is mostly sandy, whereas the loop section is mostly rocky.
This trail has no shade and no cell service. Summer hikers should start this trail before 10 am and bring plenty of water. Always check the weather forecast before heading into the park and consider changing plans if the weather conditions are too extreme. Hikers should always tell a safety buddy where they are going and when they plan on leaving the park.
The trail is not accessible for people using wheelchairs.
Pets and emotional support animals are not allowed on trails, but service animals are welcome. Service animals must remain on a 6-foot (1.8 meter) leash at all times.
