The wilderness beyond the Palm Springs Aerial Tramway mountain station is crisscrossed by 54 miles of hiking trails, including the mile-long Discovery Trail and a nontechnical but strenuous 11-mile round-trip up Mt San Jacinto (10,834ft). Free day-use wilderness permits are available at the ranger station near the tram terminal.

Applications for overnight trips cost $5 per person and can be sent in up to eight weeks in advance. See the website for the form and instructions.
