City folk are lucky to see 2,500 stars in their artificially illuminated skies, but out here among the hoodoos you see three times as many. The Night Sky Program includes low-key astronomy lectures and multimedia presentations, followed by telescope viewing (weather permitting). The program is typically offered on Tuesday, Thursday, and Saturday, May–September; the monthly full-moon hike is offered in October as well. Reservations are necessary only for the latter event;
check at the visitor center for locations, times, and other details.
