We stopped at Tower Rock for the night on our way home from Yellowstone. The campground is directly on Hwy 93 but traffic has not been too noisy. The campground is right on the Snake River and under the imposing Tower Rock. There is a mobile home park next door behind a fence. The small park is well maintained, the vault toilets are spotless. There is no water but there is trash service.
There is a platform near the river with a huge Osprey nest. We especially enjoyed watching the Osprey parents bringing fish to the 2 large chicks.
