You have to reserve your site in advance via Recreation.gov.

The park is adequate but nothing fancy. The restrooms /shower facility was clean.

Good bicycle park. Minimum 2 night stay when I reserved it (Friday Night). I only needed 1 night but paid for both - $26/night.

I didn't stay the second night because of my schedule, not because of the park. Good basic stay for the money. It was safe and clean.
