Winter is an exciting time to visit the park. As the gray whales migrate past and the elephant seals return to the Point Reyes Headlands, so do lots of visitors. This means increased traffic on the narrow roadways and in the small parking lots near the Point Reyes Lighthouse and at Chimney Rock—especially on weekends and holidays. In order to reduce traffic congestion in the Point Reyes Headlands, the Seashore instituted a shuttle bus system in 1998. Shuttle Season. The Point Reyes Headlands shuttle bus system usually begins on the last Saturday of December and continues through late March or mid-April.
