The name may say “Massacre,” but what we found was peace. Towering rock formations, desert winds brushing through sage, and the Snake River flowing like a ribbon through time. A powerful and unexpectedly beautiful stop in Idaho.

Beautiful area, spaced sort of close together depending on site. Bathrooms, electric, water, trails. Dump station close by. Only there for overnight, would love to come back for more exploring. Register rock is close by, an interesting Oregon Trail site.

I usually stay over here in the off-season, on my way from Montana to Oregon. It’s a very pleasant site, almost secluded, with some quality views of the snake River as well as Riverside access. The campsites are quite nice, there are also small cabins. Overall, a very nice place for an overnighter off the interstate.

Unfortunately the boat launch is currently under construction, making it unavailable through the fall, but I was able to slip my kayak in the Snake River via the picnic area. A paddle around the area was magical with high cliffs and boulder rising up slong the river banks. Beautiful turquoise water was too cold for swimming, but was great for birdwatching as well. Several Western Grebes were spotted raising their families along the grassy island located in front of the park. Try to get a campsite in the lower loop to be sheltered from highway noise. Nice comfort station and hiking trails along the river afford great views as well.
