How Cassidy Arch Got Its Name

The arch was named for Butch Cassidy, aka Robert LeRoy Parker, who was a bank robber and the leader of group of outlaws known as the “Wild Bunch.” He would use these hills as one of his many hideouts.

How to Hike to Cassidy Arch

Step-By-Step Trail Guide

Getting to the Trailhead

From Scenic Drive, turn left onto Grand Wash Road, which is a gravel road that is suitable for standard cars. Take Grand Wash Road to the end and park in the parking lot. There are restrooms here if you need one.

Two trails start from the same trailhead: the Grand Wash Trail and the Cassidy Arch Trail. In fact, you will briefly hike a portion of the Grand Wash Trail before turning onto the Cassidy Arch Trail.

Grand Wash Trail

The first 0.2 miles of this hike is on the Grand Wash Trail. This is a flat, easy trail that heads into a large, wide canyon. Keep an eye out for Cassidy Arch Trail, which will be on your left.

The Cassidy Arch Trail is well marked with this sign.

This sign has the wrong elevation for Cassidy Arch. Our GPS, and other sources we have read, measure the elevation at Cassidy Arch at 6,000 feet.

Cassidy Arch Trail

The first part of the Cassidy Arch Trail is the most challenging of the hike. A series of tight switchbacks climb out of the canyon and up into the colorful hills. This section does not last long, about a quarter of a mile. And it’s worth it, because for the rest of the hike to Cassidy Arch the views are wonderful.

For the next quarter of a mile, it’s a slight uphill walk that will be easy. To your right you will have a great view over Grand Wash Road.

Soon, the views open up even more, and you will be able to see Cassidy Arch off in the distance. From here, it looks more like a cave than an arch.

Roughly one mile from the Grand Wash Trail, about 1.2 miles into the hike, the trail will split. Take the trail to the left to continue to Cassidy Arch. If you go right, you will be on the Frying Pan Trail, which takes you north through the park to Cohab Canyon.

From this split, the trail gets a bit difficult to follow. The last section of trail heads up and over large bands of slickrock. Since there is no obvious dirt trail to follow, it can be easy to lose the trail. When we did this, there were a few rock cairns but these were hard to spot.

When you reach the slickrock, stay to the left. In the photo below, I marked the “trail” with a white line. Basically, you want to stay to left of the giant knobs of white sandstone.

It’s an uphill walk over these giant slabs of sandstone. In a few spots, you might have to do a bit of rock scrambling. At the top, the arch will come into view. At first, it looks like an enormous hole in the ground. On the opposite side of this hole is Cassidy Arch.

To get onto the arch, you can walk around either side of the giant hole. Cassidy Arch is very wide. It’s wide enough that if you have a fear of heights, you might be able to stand on the arch without any issues. However, I would not leave young kids unattended here, or anywhere near the hole in the ground.

To complete the hike, retrace your steps back to your car.

Optional Detour: The Grand Wash Trail to the Narrows

The Grand Wash Trail is another great hike to do in Capitol Reef National Park. You already hiked a small portion of this trail to get onto the Cassidy Arch Trail, so rather than backtracking to your car, you can continue down the Grand Wash a little farther.

We hiked the entire Grand Wash Trail and the best section is the middle third, which is called The Narrows. At this point, the canyon walls close in to their narrowest point, forming a large slot canyon that resembles the Narrows in Zion, only without the Virgin River.

This add-on is an easy way to hike through a large slot canyon and it is well worth the time and extra steps, especially if you have never done something like this before.

The Grand Wash Trail is flat and easy to walk. From the Cassidy Arch Trail, you will walk 0.9 miles to get into the Narrows. The Narrows lasts about a half mile. To get back to your car, retrace your steps on the Grand Wash Trail until you reach the parking lot.

Factoring in the return hike to your car, this detour adds 2.8 miles and a minimal amount of elevation gain onto the Cassidy Arch hike, for a total distance of 6.3 miles.

Tips to Have the Best Experience

Do not attempt this hike in the rain or when storms are in the area. To hike to Cassidy Arch, you will be parking and then hiking in a slot canyon. During storms, flash floods are a possibility and these can be deadly if you are in slot canyon.

This is a great hike for kids. The trail is short, scenic, and very fun to hike. We saw a bunch of kids on the trail when we did this, some as young as 7, and they looked like they were having a great time.

Bring sunscreen and sunglasses. There is very little shade on the trail.
