About This Trip
Alvaro's Adventures runs dedicated offshore pelagic birding trips from Pillar Point Harbor in Half Moon Bay, California, targeting the Pioneer Canyon and Cortez Canyon system — a pair of vast submarine canyons that cut through the continental shelf off San Mateo County, reaching depths of up to 1.5 miles below the ocean surface. This is genuinely deep oceanic habitat comparable to the offshore canyons of the Atlantic seaboard, producing the full range of Eastern Pacific seabirds including species rarely encountered from shore-based locations.
Trips depart Pillar Point Harbor at approximately 6:45 AM and return around 5:00 PM, spending the full middle portion of the day on the productive canyon waters. Alvaro's Adventures holds a scientific research permit (MULTI-2022-004) that allows limited use of chum to attract storm-petrels for population monitoring purposes; participants benefit from the same close-approach views this produces. The trips are led by expert guides with deep knowledge of the offshore species assemblage and have been running consistently since at least 2021, with confirmed active departures through 2025 and the 2026 season on sale.
The Pioneer Canyon pelagics target Black-footed Albatross as a signature year-round species, with Laysan Albatross increasingly recorded on winter departures (February–March). The core autumn assemblage includes Pink-footed Shearwater, Buller's Shearwater, Sooty Shearwater, and Northern Fulmar alongside Ashy, Black, and Fork-tailed Storm-Petrels — the three storm-petrel species that breed in burrows on the California and Oregon offshore islands. Red Phalarope and Red-necked Phalarope are regular in migration; Pomarine and Parasitic Jaegers are standard autumn fare; Long-tailed Jaeger and South Polar Skua are annual in small numbers on the best autumn trips. Alcids include Common Murre, Pigeon Guillemot, Rhinoceros Auklet, and Cassin's Auklet; Tufted Puffin is possible in autumn. The eBird hotspot for San Mateo County offshore pelagics (L1329104) documents the species recorded on these trips. Alvaro's Adventures also runs select departures from Monterey, Morro Bay, and Bodega Bay; check the annual schedule for current departure points.
