• Dogs welcome, but must be leashed at all times.

• The Tiburon mariposa lily, which typically blooms in May, is found nowhere else on earth.
• Wildflowers abound in spring, including milkmaids, Fremont's camas, buttercups, and shooting stars.
• A variety of raptors circle the mountainsides.
• Keep an eye out for rock wrens – this is one of the few places in Marin where the birds can be seen all year.
• Check out the iNaturalist field guide. Add your own observations.
