Find the Hidden Waterfall at Gulf Branch Nature Center

Gulf Branch Nature Center at 3608 North Military Road is Arlington’s north-county nature destination, and it packs a remarkable amount of character into a small footprint. The nature center and park feature exhibits on natural and cultural history, live animals, pollinator gardens, a vernal pond, and a restored 19th-century log cabin — the latter being one of those unexpected details that stops you in your tracks. The center also houses an observation beehive  which is exactly as fascinating as it sounds: a live, working colony of bees visible through glass, making the invisible world of the hive suddenly and completely legible. Fan favorites inside include a dugout canoe, a great horned owl named Mr. Owl, and exhibits on local fauna including snakes, with naturalist-led programs covering topics from gemology to amphibians to fish.

But the real reward at Gulf Branch is what lies beyond the building. The trail from the nature center follows Gulf Branch down to the Potomac River, passing over the creek, past an old Depression-era swimming hole, and down a waterfall to the river’s edge — a hike that feels improbably wild for a park in the middle of a residential neighborhood. Along the way, visitors pass through a grove of ancient rhododendron maximum, one of the more quietly spectacular botanical features in all of Arlington. Open Tuesday through Saturday 10 a.m.–5 p.m. and Sunday 1–5 p.m., with free admission year-round. Check the events calendar and program schedule at parks.arlingtonva.us/gulf-branch-nature-center.
