Tarantula Trek

Drop in; no registration required. $6 parking fee applies.

From Fremont, drive north on I-680 and exit at Calaveras Road (near the town of Sunol.) Turn right at the exit onto Calaveras Road and proceed about four miles to a left turn onto Geary Road, which leads directly into the park. (If you find yourself driving uphill on a narrow winding road you?ve missed the Geary Road turnoff.) To reach the visitor center take the first left after the park entrance.

From the Oakland-Berkeley area, drive east on I-580 to the junction with I-680. Take I-680 south and exit at Calaveras Road/Highway 84 just south of the Sunol exit. At the bottom of the exit turn left onto Calaveras Road and proceed as noted above.
