Edgewood is a small block of land in Redwood City, Trailheadbumping up against Interstate 280 to the west, and a residential neighborhood to the east. Now a nature preserve and park, Edgewood was protected from development by the County of San Mateo in 1993. The preserve is frequently crowded with joggers and picnickers, and it's tough to achieve any sense of quiet nature with the almost constant sounds of highway traffic, the shriek of airplanes flying at low altitude, and the everyday buzz of chainsaws and dogs barking at the nearby houses. Still, this preserve is a short drive from San Francisco and peninsula communities, there are quiet places to be found, and the well-maintained, easy-to-hike trails make it a worthwhile escape destination for short hikes. Sylvan Trail
      Sylvan Trail gets the most use in this preserve -- it's part of a 2.5 mile hiking-only loop that winds gently through a coast live oak and California bay woodland, ascending to an open grassland plateau and then descending back down to the picnic area. This loop has mileage markers every half mile and is well graded, so it is an excellent exercise path, and an easy trail if you are feeling out-of-shape.
     Several loops are possible, and you can vary your hikes by entering the preserve via the one major trailhead or any of the three other small staging areas. Combine legs of Serpentine Loop, Ridgewood Loop, and/or Sylvan Loop for a hike from 2 to 4 miles.
     Edgewood's western section, along 280, is mostly grassland. There are pockets of chaparral along Clarkia Trail, Sylvan Loop, and Ridgewood Loop, Sylvan Trailbut most of Sylvan is shaded by coast live oaks and California bays. All this variety translates into a paradise for wildflower lovers in spring, when you'll see different blossoms in the woods, serpentine grassland, and chaparral. Late summer is also lovely, thanks to the preserve's copious amounts of poison oak, which turn flame red along the trails. Winter is often a muddy time to visit.
     For a just over 4-mile circuit of the preserve, walk from the parking lot south towards the picnic area. As the path rises slightly, you'll reach a signed T junction at about 200 feet (the path to the right heads towards the picnic areas, and the restrooms). Turn left on Sylvan Trail.View from Sylvan Trail, north
      Keep an eye out for the many runners who uses this trail, but cyclists and equestrians are prohibited. In late winter, blossoms from flowering plum trees litter the trail like confetti. Later in summer, the preserve's wild animals feast on the ripe fruit, and you might notice scat studded with plum pits. On one July hike I got a glimpse of a young coyote just off the path here. Sylvan is mostly shaded from coast live oaks and California bays, with a few madrones and buckeyes. Honeysuckle vines dangle from the trees, bearing red berries in late summer and early autumn. At 0.17 mile, Sylvan Trail splits at a signed junction (number 7). Bear left.
      In early spring, you may see woodland star, fat solomon, snakeroot, mission bells, and figwort. Hound's tongue, a prolific flower in late winter, may already be dangling seeds for next year's plants. After winter rains, there are two lovely small waterfalls, and the sound of running water will keep you company as you ascend along the trail, which is likely to be muddy. Maidenhair fern and creambush are common along the wettest sections of Sylvan Trail, View north from Serpentine Loop Trail but you'll pass through patches of chaparral as you gain elevation, where you might see monkeyflower, bush lupine, chamise, poison oak, clematis, blue elderberry, coyote brush, sagebrush, hollyleaf cherry, and toyon. At 0.54 mile a closed trail spur breaks off from the left side of the trail. Continue to the right. In the dry months of summer red-leaved poison oak shrubs dominate the landscape; those "leaves of three" mingle with dry downed buckeye leaves, in sharp contrast to the lush green trailside vegetation of late winter and spring. As Sylvan Trail enters grassland, in early spring you might see dramatic stands of red Indian warrior, and the delicate purplish-blue blossoms of blue-eyed grass and bluedicks. California sagebrush and sticky monkeyflower grow here and there. Coast live oaks thin a bit, making room for some madrone, and a handful of white and blue oaks. Just past the 1 mile marker you'll reach a signed junction (16) with Serpentine Trail. Continue straight on Serpentine Trail. Serpentine Loop Trail(Option: you can shorten this hike to about 3 miles by turning right on Serpentine Trail. The narrow trail, open to hikers and equestrians only, steps under shade created by tall California bays, then reemerges in grassland. At 1.43 miles, turn right onto Old Stage Road and continue the featured hike).
      Open to hikers and equestrians, Serpentine Trail switchbacks up a grassy hillside. Take a moment to enjoy views north, past Edgewood's softly rolling hills to Pulgas, and east, where you should be able to pick out the shoreline of Bair Island. At a signed junction (19) at 1.39 miles, Live Oak Trail heads off to the right. Continue straight on Serpentine Trail.
     Fences protect the habitat along the trails, including the hillside to the right, which is scored with unsanctioned paths. When I hiked here in July I flushed a hawk off of a boulder and then, a moment later, scared away two deer. On more than one occasion in this section of the park I have watched jackrabbits bounding through the grassland. Look to the left for good displays of fragrant fritillary in March. The trail winds slightly uphill to a signed junction (20) at 1.55 miles. Turn right onto Sunset Trail.Serpentine Loop Trail
     In spring, the sides of the trail are carpeted with native wildflowers that thrive in the serpentine soil. You might see owl's clover, blue-eyed grass, bluedicks, goldenfields, creamcups, tidytips, larkspur, checker-bloom, and many more. This is one of the best, and most accessible locations for wildflowers in the bay area, and is also home to endangered butterflies. Sunset Trail gently descends to the west, with nice views to the forested slopes of the Santa Cruz Mountains. At 1.77 miles, Clarkia Trail sets off to the left at a signed junction (22). Continue straight on Sunset Trail.
     The trail skirts the chaparral-studded slopes of Edgewood's highest hill. Sporadic clumps of coyote brush, California coffeeberry, poison oak, toyon, and gooseberry line the trail. Park staff has been mowing the grassland, an attempt to contain a yellow star thistle invasion, and several interpretive signs explain the project. Traffic noise from Interstate 280 is unavoidable, and as you head north vehicles are visible as well.At 2.38 miles, you'll reach a signed junction (14) and information kiosk. The trail to the left leaves the park and passes under the highway, leading to Edgewood Road (and continuing to Cañada Road). Continue straight, now on Edgewood Trail.Service Road
     Two junctions are reached in quick succession. The first (13), at 2.43 miles, heads right, uphill to Live Oak Trail. Continue on Edgewood Trail. Next Edgewood Trail slips off to the left at 2.57 miles (junction 9). Continue to the right on Serpentine Trail.
     The wide trail curves east and climbs gently, reaching a flat grassland plateau. At 2.83 miles, Serpentine Trail veers right at a signed junction (10) with Old Stage Road. Bear left.
      The broad dirt trail is open to hikers and equestrians only. In spring, the grassland is full of blooming wildflowers, including pink farewell-to-spring, yellow California buttercups, suncups, and goldenfields, white popcorn flower, and orange California poppy. Old Stage Road heads downhill to the north, offering views to Pulgas Ridge. A sign encourages you to stay on the trail. At 3.12 miles (junction 6), turn right onto Franciscan Trail.
      The narrow path winds along the edge of the meadow, past a large rock outcrop, and reaches junction 8 at 3.34 miles. Turn left onto Baywood Glen Trail (formerly named Sylvan Loop). Sylvan Trail
      Like the other leg of the loop, Baywood Glen Trail is open to hikers only. A gradual descent on switchbacks takes you back into the woods, mostly California bay and coast live oaks, with some madrone and buckeye. Look for prickly-stemmed gooseberry, toyon, and in the spring, zigadene, hound's tongue, and shooting stars growing close to the ground. As I hiked downhill here in July 2001, an emergency vehicle, siren blaring, could be heard on nearby Edgewood Road. As the siren screamed, a coyote (close by but obscured by the woods) responded, with a distinctive yip and then howl. At the previously encountered junction, at 2.71 miles, take the trail left and retrace your steps to the parking lot.

Total distance: 4.16 miles
