The Skull Crack Trail at Causey Reservoir is a scenic hike just 45 minutes east of Ogden, Utah. Nestled at 5,700 feet in elevation, this 142-acre reservoir is surrounded by steep, forested canyons that branch into three distinct forks, offering hikers stunning views and a peaceful escape into nature.

About

The Skull Crack Trail is a 5-mile roundtrip hike that leads to the end of the Right Fork of the South Fork Ogden River. This easy-to-moderate trail is especially popular in the fall during the Kokanee Salmon run, when vibrant red salmon swim upstream to spawn. Peak salmon viewing typically occurs in mid-September. Along the way, you’ll enjoy vibrant fall foliage, panoramic views of Causey Reservoir, and a peaceful trail ideal for dogs (off-leash allowed) and kids.. 

Directions

Parking is available at the trailhead, located at the southern end of Causey Reservoir. A single restroom is located at the trailhead. Use this Google Map map.

The Skull Crack trailhead parking area. It’s located at the southern end of the reservoir, where the road ends.

The sign says 2.3 miles one way, but I tracked 2.5 miles.

The water level looked really low, even though we had an amazing snow year in 2023.

Towards the beginning of the trail, you will hike up on small hill. You will also get great views down to Causey Reservoir, of course.

Sections of the trail are somewhat shaded but it’s mostly exposed. This is another reason why Fall is a great time to hike here – cooler temperatures!

You’ll get up much higher above the reservoir as you continue to hike. You should have some pretty amazing views of the lake.

Finally the trail begins to descend, and you can now see the stream.

One of the most unique aspects of this hike is witnessing the Kokanee Salmon run each fall. Thousands of bright red salmon swim upstream to spawn—a breathtaking and rare sight in Utah. I first discovered it thanks to a friend, and it completely exceeded my expectations. While 2016 was a peak year (as seen in the photo), the salmon population varies year to year. You never quite know what you’ll see!

And this photo is from 2023. Wow, what a difference. I don’t know if it was from timing or if there was just a lower population of Salmon this year. You never know what you will see when you arrive.
