The trail starts as a gravel track alongside the brook and becomes a more scenic winding path about halfway through. The wilderness here is delightful and the views at the end of the hike are fabulous.

From here you get a fantastic overlook to the northern Sawtooth range. In the summer you will be surrounded by wildflowers, and in the autumn by stunning leaf color. There is a campground with vault toilets and Howell Creek Spring is just down the road.

Frequently Asked Questions

When is the best time to hike in Cassia County?

The prime hiking season in Cassia County is from late spring to early fall. Lower elevation areas like the City of Rocks are accessible for a longer period, but summer can be very hot. Higher elevation trails in the Sawtooth National Forest, especially around Lake Cleveland, are best from July to September when the snow has melted and wildflowers are in bloom. Always check local conditions before you go, as weather can change quickly in the mountains.

Are dogs allowed on hiking trails in Cassia County?

Yes, many trails are dog-friendly, but regulations vary. In the Sawtooth National Forest, dogs are generally welcome on trails but must be under voice or leash control. In City of Rocks National Reserve and Castle Rocks State Park, dogs are permitted on trails but must be on a leash no longer than six feet at all times. Always pack out waste to help keep the trails clean.

What are some easy, family-friendly hikes in the area?

Cassia County has several great options for families or those looking for a gentle walk. The Parking Lot Rock loop from City of Rocks National Reserve is a short, accessible trail that offers fantastic views of the granite formations. For a pleasant walk through the forest, the Thompson Flats Trail is an excellent choice. Near Burley, the paved Riverside Trail provides a flat, easy stroll along the Snake River.

Are there any hikes with waterfalls or lakes?

While large waterfalls are not a primary feature of the region, you can find beautiful water-centric hikes. The Albion Mountains contain several stunning alpine lakes. For a more challenging day out, you can hike to the remote Independence Lakes in the Sawtooth National Forest. For river views, the trails along the Snake River, such as the Snake River Canyon Rim Trail near Twin Falls, offer dramatic scenery.

What kind of wildlife might I see while hiking?

The diverse ecosystems in Cassia County support a variety of wildlife. In the forested areas of the Sawtooth National Forest, you might spot mule deer, elk, and various bird species. The rocky landscapes of City of Rocks are home to smaller mammals like marmots and pikas, as well as birds of prey. Remember to observe all wildlife from a safe distance and never feed the animals.

Can I go mountain biking in Cassia County?

Absolutely. The region is popular with mountain bikers, offering trails for various skill levels. Many of the multi-use trails in the Sawtooth National Forest are open to bikes. Pomerelle Mountain Resort also opens its lifts for mountain biking during the summer, providing access to downhill trails with panoramic views of the surrounding area.

What are the trail conditions generally like?

Trail conditions vary significantly by location and season. Trails in City of Rocks and Castle Rocks are typically well-maintained and marked, featuring sandy or rocky paths. In the Sawtooth National Forest, trails can be more rugged, with potential for downed trees or muddy sections, especially after rain or during the spring melt. It's always a good idea to wear sturdy hiking shoes with good traction.

Are there any circular or loop hikes available?

Yes, the area has several excellent loop hikes that bring you back to your starting point without backtracking. For an easy but scenic option, consider the Stripe Rock Loop, which showcases the unique geology of the reserve. Another great choice is the Backyard Boulders Trail Loop, a short and enjoyable walk within Castle Rocks State Park.

What do other hikers enjoy most about Cassia County?

The region is highly regarded by the komoot community. Reviewers frequently praise the stunning and unique granite landscapes of City of Rocks National Reserve, which provide a dramatic backdrop for hiking and photography. The peaceful, forested trails and alpine lakes in the Sawtooth National Forest are also highlighted as a welcome escape.

Are there any challenging hikes for experienced trekkers?

For those seeking a challenge, the Albion Mountains offer more strenuous routes with significant elevation gain. The hike to Graham Peak from Emery Pass Picnic Area is a demanding trek that rewards hikers with expansive views from one of the highest points in the area. These high-altitude hikes require good fitness and preparation.

Where can I find information on parking at the trailheads?

Most major trailheads in City of Rocks National Reserve, Castle Rocks State Park, and the Sawtooth National Forest have designated parking areas. Popular spots can fill up quickly, especially on weekends, so arriving early is recommended. Some trailheads are located along dirt or gravel roads, which are generally passable for most vehicles but may require careful driving.
