PISCATAWAY PARK LENGTH: 8.5 miles CONFIGURATION: Modified out-and-back DIFFICULTY: Easy–moderate SCENERY: River views, wetlands EXPOSURE: Mostly open; more so in winter TRAFFIC: Very light–light; heavier on warm-weather weekends, holidays at colonial farm TRAIL SURFACE: Chiefly dirt or grass; marsh boardwalk, short stretches of gravel, pavement HIKING TIME: 3.5–4.5 hours ACCESS: Open daily, dawn–dusk; entrance fee MAP: USGS Mount Vernon FACILITIES: Toilets, water at visitor center (near trailhead; closed on Mondays); toilets along Piscataway Creek trail In the late 18th century, the view across the Potomac River from George Washington’s Mount Vernon estate was one of woods and cultivated fields. More than two centuries later, it still is. A mix of private and public actions saved the developmentally challenged shoreline lying only 14 miles south of the White House. In the early 1950s, local groups and citizens launched an effort to protect it. Then, in 1961, Congress authorized Piscataway Park to preserve “the historic and scenic values . . . of lands which provide the principal overview.” Using more easements than ownership, the present-day park extends along the riverbank for about 6 miles and covers about 5,000 acres. This hike is a country ramble in an area where past and present mingle. It includes a reconstructed colonial-era farm featuring now-rare crops and livestock breeds, as well as a modern organic farm. Among its other attractions are views of Mount Vernon, a Native American ceremonial site, an arboretum, and a marsh. The mostly level, 8.5-mile hike is only partially blazed and signposted, so follow my directions closely, especially on the segment after the colonial farm. Also, expect little shade and a bit of mud. To get started from the trailhead parking lot, walk back to the paved road. Turn left onto the grassy shoulder and walk along the edge of the woods for about 50 yards. Turn left onto the Blackberry Trail at a half-hidden trail sign. Follow the purple blazes through the woods. At the far side, you’ll reach the fenced-in, eight-acre Robert Ware Straus Ecosystem Farm. It develops improved methods of intensive and sustainable organic farming. Like the colonial farm, it’s run by the Accokeek Foundation at Piscataway Park, which also manages the park’s trails and visitor center for the National Park Service. Touch not the electrified anti-deer fence. Turn right to walk along it. At the end, turn right onto an open gravel road. At a paved road (Bryan Point Road), turn left, and follow the shoulder for 200 yards, staying left. Then, at the “Tayac” sign, turn left onto a dirt road and follow it through fields going wild. Cross a parking lot onto a woodland path, then settle in for a scenic hike of just over a mile along the river. The hike begins with a boardwalk jaunt across a large freshwater tidal marsh fed by Accokeek Creek. In the warm-weather months, the marsh is a green carpet dotted with color, mostly the red, pink, or white blooms of flowering plants and the wing patches of red-winged blackbirds. Water birds ply the shore. Insects create a sonic background for the boom of a bullfrog or the whistle of an osprey. In winter, you’ll mostly experience browns, grays, and silence. The browns may well include bald eagles. After the marsh, you’ll pass through a small wooded swamp and then step off the planks and onto a paved woodland path. About 20 yards later, step into the open at a junction with an unpaved farm road. Turn left and follow the road along the riverbank to the site of a large, precolonial Piscataway village. The area remains sacred to the villagers’ descendants, who gather there each spring for a ceremony. Pause to view the ceremonial wigwam, other artifacts, and the plaque honoring Chief Turkey Tayac (1895–1978). Continuing, stay near the river, which is shielded by thickets. The passing fields are part of a special farm where schoolchildren learn about farming and ecology. Eventually, you’ll enter some woods and leave the river as the road swings right. When you next reach the water, it’ll be at Piscataway Creek’s estuary—also the turnaround spot, 2.25 miles into the hike. Look around, and note the bushes brightened in summer by honeysuckle flowers, butterflies, and dragonflies (and poetically remember the dragonfly hanging like a blue thread loosed from the sky). On the estuary’s far side, look for mammoth Fort Washington, built in 1824 to guard the river approach to the capital. Then begin your return to the ecosystem farm. En route, just after the end of the boardwalk, detour for a quarter-mile round trip into the marsh on a trail bordering Accokeek Creek. Watch on the left for an observation platform. Use it to marsh gaze, and then walk back. At the ecosystem farm, again, change course. First, you’ll proceed along the fence all the way to the end. Then turn right along a second fence line. Turn left at the second side trail, near bluebird box number 42; and walk to the riverbank. There, at the farm’s solar power generator, eyeball Mount Vernon, turn left, and follow the grassy riverbank path. At a trail junction (that’s the Blackberry Trail again, on the left), proceed on the signposted and yellow-blazed Pumpkin Ash Trail, which leads a half mile to the visitor center. From the center, head west on a dirt path. Just before getting to an avenue of cedars, turn right onto the signposted Riverview Trail. It’s an open, blue-blazed, mowed-in-season grassy trail that’s 0.8 miles long but hidden from the river by thickets. On approaching a fenced enclosure, leave the trail to turn right and then right again to take a stairway to the boat dock. The dock provides a fine view of Mount Vernon year-round. Back on the main trail, detour to the enclosure known as the Museum Garden. A key part of the National Colonial Farm, it features plants grown and used by the colonists. Later you’ll see more of the farm and perhaps some staff members and volunteers, who wear period garb and interact informatively with visitors. After leaving the garden, turn left, walk to the end of the fence, and turn right onto a gravel road. After passing the caretaker’s residence, a driveway, and an old out-kitchen on the right, leave the road and swing right onto a grassy trail (part of the Riverview Trail). Follow it past a pond on the left. Then swing sharply right and head into the woods on a dirt trail. Soon after crossing a stream and out in the open again, turn right at the first of six junctions and walk past overgrown fields. Turn right at the next junction. Turn right at the third junction, along the shore, and swing left along the edge of the woods. Turn right at the fourth junction, out in the open. Turn right at the fifth junction (ignore the trail sign pointing straight ahead to the Bluebird Trail), and walk about 50 yards uphill—to the sixth junction. There, turn right and then left onto the signposted and white-blazed Pawpaw Trail. It’s a narrow dirt trail that arcs for half a mile through a hilly and heavily wooded area. Watch for labeled trees, mature trees, baby trees (especially pawpaws), wildflowers, and poison ivy. The Pawpaw Trail ends at the upper edge of a mowed area dotted with labeled young trees and shrubs representing more than 125 species that grew in southern Maryland in the colonial era. They make up the park’s six-acre Native Tree Arboretum, started in the 1980s. Roam among the plants and then follow the edge of the woods westward (away from the Pawpaw Trail). Turn left onto a gravel road (part of the Bluebird Trail), walk ten yards, and turn left again onto a grassy path to semicircle around what park literature alleges is a chestnut grove. Continuing, you’ll arrive at the junction of the Pawpaw Trail and the short trail up from the Bluebird Trail. This time, turn right onto the short trail and then right again onto the blue-blazed Bluebird Trail, and head out into the open. Follow the road east, between a pasture on the left and the lower part of the arboretum on the right. Beyond the pasture, turn sharply left to stay on the gravel road and Bluebird Trail. Heading north, follow the road as it swings right past some stables and reaches a junction. There, turn sharply left and continue, following the blue blazes past the farm’s livestock area. Then pass the driveway again. Continue, keeping the Museum Garden on your left, and head down the cedar avenue that leads to the start of the Riverview Trail. At the end of the avenue, detour through a gate on the right to circle past the colonial farm’s old farmhouse, out-kitchen, smokehouse, “necessary” (outhouse), and kitchen garden. Then return to the trailhead.
