Willow Bay Resort

7 ReviewsAdd Review

Sitting along the shore of American Falls Reservoir in southern Idaho, Willow Bay Resort gives campers direct access to the water with full hookups, pull-through sites, and a range of access modes including boat-in and drive-in. Rates run $25 to $55 per night, and the resort operates year-round. Sites are notably large, with grass areas, picnic tables, and fire pits, though fire restrictions may apply during low-water conditions. Restaurants and a grocery store are within a five- to ten-minute drive.

Water levels at the reservoir fluctuate noticeably by season, and several reviewers visited when the lake was low enough to leave the marina dry-docked. The timing of a visit matters here. When water levels recover, the resort has boat launches and swimming access within walking distance of the sites. Trails nearby accommodate bikes and off-road vehicles, and the sites offer open sightlines toward the surrounding mountains.

Amenities include a bathhouse with showers and a laundry, a dump station, and WiFi. The restrooms have drawn mixed feedback, with at least one reviewer noting aging facilities, a non-locking shower door, and limited hot water. Construction noise has also been mentioned by a recent visitor. Debra M. describes the sites as having "very large spaces and well kept," and staff responsiveness comes up consistently across reviews. Campers planning a trip to the area can also browse sites near American Falls or consider Willow Bay Campground, a separate nearby option a short distance to the southeast.

A great overnight Stay

The leaves were out on the trees, the water level had returned and the park was enjoyable.  The staff was very helpful in getting us to our pull-thru.  Had a restful night

Basic and noisy - needs an update

The restrooms are very old and not very inviting (a lot worse than most of the state parks I‘ve visited), shower door didn‘t lock, water was rarely warm and in the men‘s shower there was no light. Construction work began in the early morning, which was much noisier than the nearby railroad..

Nice Location

We stopped her in October and  the water level was extremely low.   The boats were dry docked and could not access the marina.  We chose this campground because we wanted to visit American Falls, which we did.  The area was beautiful, but there was not enough water to create a fall.  

The campground is very peaceful with very large spaces and well kept.   We has a large grass area with a picnic table and fire pit, fires were prohibited while we were there because of the low water conditions.  Behind our space was the river/lake area that was dry.   Still the park had great views of the mountains and was very pretty.   There are many trails around for bike riding or off road vehicles.   

The sites are full hook up, there is a bath/shower house and a laundry.  The staff is very helpful.  We were a bit early and when we arrived Jason was mowing our space.  It was completed very quickly.  There are restaurants in town about 5-10 minutes away and a grocery.  Wifi was excellent on T-Mobile and Visible.

A Last Resort

So, this campground is a bit flat, and just no character to it. Just plain. Luckily it’s right near the water. They do have bathrooms and showers. Small place to eat and walking distance to the water to swim in. This I see as a day trip..
