Pescadero Marsh Natural Preserve

Right next to Pescadero Beach, which I visited before, there is also a wetland area with established trails. With its mix of estuary, coastline, and wetlands, it seems like an excellent spot for wildlife observation. Unusually for this stretch of coast, there’s also free parking available. I decided to revisit for the first time in a while. It’s about a 20-minute drive south from Half Moon Bay.

Canada Goose standing on a fallen tree. In fact, the trail in the wetland mentioned in the title was closed for construction, so this time I explored the surrounding area instead. The banks of Pescadero Creek, which flows alongside the trail, also seem promising. There are many fallen trees, perhaps carried there by flooding.
