Willow Glamping Yurt

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.

Rental Fee and Reservations

Occupancy for this facility is no more than 4 people and 2 cars. *Note that only one $7.00 motor entry fee is included in your reservation fees. Other vehicles must pay the $7 motor vehicle entrance fee per night. Those are acquired at the visitor center. If you have an Idaho State Parks Passport or Annual Pass, that fee is waived.

The Almo Creek Cottage

Castle Rocks State Park offers “The Almo Creek Cottage” for rent, located next to The Ranch House. This facility is perfect for families or couples. The Almo Creek Cottage offers a rustic and primitive lodging in a communal setting. Guests are housed in an open, one room building with scenic Castle Rocks as the backdrop to the experience.

What’s inside?

A comfortable 20×26-foot living area, accommodating up to 7 occupants, that consists of a kitchen/dining area and sleeping-quarters.

The Almo Creek Cottage has 1 king-sized bed, a hide-a-bed couch that folds out into a queen-sized bed, a small sofa that folds out into a full-sized bed, as well as 2 ottomans that can be folded out into single beds. Has linens and bedding and is equipped with electricity, a hot-water sink, small fridge and freezer, and trash receptacles. Furniture includes corner nook table, cabinets, granite countertops, flatscreen TV, and in-unit heat/ac. Limited kitchen supplies are provided including pots, pans, cookware, mugs, plates, utensils.

Guests must supply their own food, towels and other personal gear. A restroom with flushing toilet and a shower is located behind the Almo Creek Cottage and can be accessed using the same PIN code provided to cottage reservation-holders. There are additional showers available at the Smoky Mountain Campground.
