Blink and you'll miss it. Roy's Redwoods in West Marin has no signs pointing to it and no parking lot. You've just gotta know where to go (directions below). Begin a gentle 2-mile walk at a tranquil green meadow surrounded by laurels and madrones. Walk through the meadow to a hefty cluster of redwoods; these are Roy's big boys, reaching so high into the sky that not much light beams to the needle-covered floor. Pop out on the other side of the grove and follow Roy's Redwoods Loop Trail until it connects to the Nature Trail, a short loop-hike around Nicasio Hill. There are no big views, but there is plenty of canopied forest with sections of mighty lightening-scarred redwoods. We're not sure who Roy is, but we like hanging out at his place.

Before you go, print out a map here; none are available at the park. Directions to Roy's Redwoods: From Hwy. 101 northbound in Marin, take the San Anselmo exit; stay in the left lane and continue on Sir Francis Drake Blvd. heading west. Go 10.5 miles and turn right onto Nicasio Valley Rd. Go .5 mile and park in one of the turn-outs. The trail starts on the right (east) side of the road. Follow the trail through the meadow. Continue past the redwoods on a faint trail up to Roy's Redwoods Loop Trail and go right. At a four-way junction (where a spur trail goes left to a hilltop view), go right onto the Nature Trail (or "David Hansen Trail" on the map). Make a loop; then go back to your car the way you came.
