Three Rivers Trail: Officially considered the nature trail of the park, this trail, blazed with blue hexagons, has seen better days. Many of the piers that once dotted the Tillery shoreline have fallen in, but the trail is still commonly hiked. The trail, starting in the Tillery/Boathouse parking lot, goes through marshes and woods, connecting all of the park's ecosystems along one short trail. After passing through marshland and coastline, the trail ascends a small hill, where hikers can find deep woods and wildflowers. The trail then slowly descends the mountain.
