Bolinas Lagoon
2026 pups:
237
A tidal lagoon behind the Seadrift sandspit at Stinson Beach. Pups split almost evenly between Pickleweed Island and the Highway 1 channel, with about a quarter on Kent Island. It had the most pups and molting seals of any site in 2026, an above-average year.

Drakes Estero
2026 pups:
172
A shallow, branching estuary that drains into Drakes Bay. Most seal pups are counted on Oyster Bar and A1 Sandbar. Long one of the park's most productive pupping sites, it posted a record-low count in 2026 — monitors reported coyotes on site.

Double Point
2026 pups:
108
A remote stretch of the southern Point Reyes coast, where pocket beaches sit beneath the cliffs. South Beach now holds about three-quarters of the pups counted here, while North Beach, which held more than a third a decade ago, has nearly emptied. Counts in 2026 were the lowest on record, and coyotes were documented here too.

Duxbury Reef
2026 pups:
6
A broad shale reef off Agate Beach near Bolinas, exposed at low tide and surveyed as a single haul-out rather than split into subsites. Few pups are born here, and the 2026 count was similar to the long-term average.

Point Bonita
2026 pups:
5
Rocky coves below the cliffs at the tip of the Marin Headlands. Surveyors work through 20 numbered coves, but since 2021 more than half the pups have come from just one of them. Many adults rest here, but few pups are born. The 2026 count was in line with the long-term average.

Tomales Point
2026 pups:
41
The northernmost point on the Point Reyes peninsula, where Tomales Bay meets the open Pacific. Since 2021, nearly every pup counted here has been on two haul-out sites: Bird Rock, which has about two-thirds, and Rope Beach. The 2026 pup count was the lowest on record.
