To avoid the road construction on Riordan Rd (now through June 20th), we recommend approaching the park from east through Northern Arizona University. The main park entrance is just west of the Riordan Rd and Knoles Dr. intersection. Please call the park at 928-779-4395 for further directions.
The main entrance and parking lot are located at 409 W Riordan Rd., two blocks east of Milton Rd. next to the NAU parking garage.
