We love the park
Massacre Rock State Park is a popular destination for boaters. Nearby are two reservoirs, but the water levels vary so much on the reservoirs that boating can be unreliable for those traveling long distances. American Falls reservoir was at 24% capacity when I visited in September. I’m told they fill it back up for ice fishing, if that is of interest to anyone. For that reason, Massacre Rocks SP is busy on the weekends.
There is an upper loop and a lower loop. Both have pros and cons. The upper loop can be windy, a blessing on hot days, but it could become too windy for your awning or canopy. The views are better, especially site 13 and 14. Site 13 has a huge space behind it with a ton of privacy. The road noise is more noticeable in the upper loop as well. I don’t really hear it after a day, but it does take away from the nature vibe.
The lower loop is winding and less suited for big rigs. The sites are short. There is one pull through, but the site is not level. Take care to look at driveway lengths and know that some of the turns are tight. Most 5th wheels that found space in the lower level had to disconnect the truck and park it at an angle.
The camp hosts are nice and leave the guest alone for the most part. There is an interpretive display within the campground. You can buy ice and firewood. The nearest town is American Falls, about 10 miles away, 2 exits on the freeway. The nearest place to buy hard alcohol is Pocatello, so plan accordingly. There are easy hiking trails within the campground. You can play disc golf and find the day use areas.
Swimming is strongly discouraged. The current can be strong at times. A kayak would be fine, but I wouldn’t take a paddleboard out. Technically, the park owns the property only to the water line. The water is Water Reclamation Bureau property and the land on the other side is BLM, so technically the park can’t forbid you from swimming. Still, there is no one to save you if you get into trouble. If you don’t have a boat, there isn’t a lot to do here.
Site #31 lower loop is excellent. Private and view of the snake river and easy access. Fwy noise not a problem. Perfect hook up. It’s R n R time.
