Fodor's Expert Review Old Mill Park
Mill Valley
City Park
Free
To see one of the outdoor oases that make Mill Valley so appealing, follow Throckmorton Avenue west from Lytton Square to Old Mill Park, a shady patch of redwoods that shelters a playground and reconstructed sawmill. The park also hosts September's annual Mill Valley Fall Arts Festival. From the park, Cascade Way winds its way past creek-side homes to the trailheads of several forest paths.
