Park is easily accessible from I-80, just be aware of your directions and make sure they’re taking you to the park via Rocky Road. Mine did not, and I ended up down a seasonal road that did not end at the park entrance. With the right directions, it’s easy to find. You will be driving down into the valley, which can feel very steep at times.
Park was very quiet in terms of sites being used. Only one other site was occupied. Tent only sites were very nice and most were spacious. The road that park is on is busier than one would think, not bad at night, but busy in the morning. Also, the nature noise here is loud. If you camp on the sites by the river, be prepared for lots of noise from the rapids. It had been raining quite heavily all day, so this may have impacted the volume levels. Nature noise is not something I would normally complain about, but this seemed noticeably loud. Bathrooms were small, but clean and adequate.
Overall, this park was very nice. I wanted a place to stop overnight, and this worked out really well. I would camp here again.
