While Point Reyes National Seashore is not a (wildlife) sanctuary, in many ways it presented itself that way, on my first ever visit there. Point Reyes has it all: bays, lagoon, ocean, lighthouse, cape, and LOTS of wildlife. Amazing, beautiful wildlife.
I included too a sprinkling from another brief but wonderful spot called Shorebird marsh in Corte Madera. Many new water birds (to me!) including a stunning flock of American Avocet.
