This is our favorite hike in the bay. The trailhead is located right behind the Stinson Beach Fire Station. For an easier, shorter hike and quick access to the beautiful landscape at Trojan Point, you can enter from the top at Pantoll Campground (fee for parking). Trojan Point looks like a Wendy Gruber painting : )
At roughly 20% larger than Central Park in NYC, there's no shortage of activities in Golden Gate Park. The de Young Museum, Academy of sciences, Botanical Garden, Conservatory of flowers, Stow Lake Boathouse. You might find some bison roaming around or Justin Forth in the disc golf course.
