With hundreds of routes to explore, the challenging landscape of Castle Rocks State Park attracts rock climbers from around the world and provides superb hiking, mountain biking, and horseback riding in the midst of a dramatic backdrop that dates back 2.5 million years. Remnants of Native American pictographs, historic trail crossings, and 20th century ranching are visible in the park today.
Evidence suggests that folks have been coming to Castle Rocks for nearly 9,000 years. Campsites are nestled among Idaho’s largest pinyon pine forest on the east slope of the 7,500-foot Smoky Mountain.

“The Ranch House” is a century-old ranch house completely remodeled to blend the quaintness of yester-year with the convenience and comforts of today. The Ranch House is available year-round, and reservations are recommended.
The Ranch House can accommodate up to 8 people and offers a master bedroom with queen-size bed, flat screen TV/DVD and reading room/den. A TV room with flip-flop sofa converts into a sleeping room for two. A third sleeping room provides a double/twin bunk bed for up to three, and a fourth, “the quiet room” has a twin bed, desk, and private deck.
Other rooms include the fully equipped kitchen, spacious bathroom with tub/shower, dining area, and living room with propane fireplace.

Glamping is the catchword for “glamorous camping” and a new kind of facility that is sweeping the country. The Willow Glamping Yurt, located in Castle Rocks State Park, offers upscale accommodations in a 22-foot diameter yurt. The facility includes a king size bed, quality furniture, electricity, electric fireplace, mini fridge, microwave, coffee maker, and artistic decor. A futon provides the option of accommodating up to 4 people.
The facility sits at the end of a private drive near the Castle Rock Ranch House and the Almo Creek Cottage. The yurt is relatively out of sight and yet has a five-star view of the Castle Rocks geological area as well as the 10,339-foot Cache Peak, the highest mountain south of the Snake River in Idaho. Yurt guests will enjoy the spacious deck and stairway that leads to the tumbling waters of Almo Creek and willow thickets that shelter wildlife from migratory birds to moose.
The Willow Glamping Yurt provides a different kind of experience than the Ranch House or Almo Creek Cottage, and it is still considered camping. For instance, the restroom is located 510 feet away, much like it would be for campers in Smoky Mountain Campground. Yurt guests are able to take showers in the campground, but must travel a couple miles to that facility. In the future new facilities may be located much closer to the yurt and cottage.
