Summer weekend service was restored to Big Basin on Route 35 in 2023. Route 35B provides seasonal (spring and summer) service on weekends and holidays to Big Basin Headquarters. Buses depart from the Cavallaro Transit Center in
Scotts Valley approximately every two hours between 8 AM and 4 PM, arriving at Big Basin approximately 45 minutes later. Return buses depart from Big Basin with approximately the same two-hour headways, between 8:45 AM and 5 PM.
