The best views are after a winter storm a snowy Sierra shows up better, and summer days are likely to be hazy. On a clear day, the Sierra Nevada range is plainly visible from the summit. The day use fee per vehicle for the park is by entrance way: $6 via Macedo Ranch (Alamo) or Mitchell Canyon (Clayton), and $10 via South Gate Rd.
