The easiest access is via Rocky Gap Road
via Red Rock Canyon, which is only available during park hours and requires payment by way of a day or annual pass.
This trail leads to the top of North Peak from Rocky Gap Rd with amazing views of the back of the Red Rock Escarpment (including the bridge on Bridge Mountain), Red Rock Canyon, and all of of Las Vegas beyond. You can also use this trail to return to Rocky Gap Rd after coming up Giant's Mile
to the north.
