It is a 21 mile, mostly gravel, road usually passable by normal passenger car. RVs over 24 feet are prohibited, due to the twisting and dipping nature of the road. During the winter and early spring (January-March) Ranger guided van tours are available. Sign up at the Kris Eggle Visitor Center for a seat on the van.

    The Puerto Blanco Drive is the other popular road in the park. This road has been reconstructed for five miles provideding access to the Pinkley Peak Picnic Area. Several stops along the way provide wonderful views and information on the ecology and culture of the Sonoran Desert. The remainder of the Puerto Blanco and Pozo Nuevo Roads are closed.

  • Camping
