🏝️ Island Park on the Snake River — Maya Lin Art, Nez Perce Heritage, Swimming Beach, and Marina — A 282-acre island park on Lower Granite Lake with camping, marina, sandy beach, Maya Lin’s “Listening Circle,” and Nez Perce cultural history — near Clarkston, Washington
Chief Timothy Park occupies an entire island in the Snake River — 282 acres of Silcott Island on Lower Granite Lake, connected to the mainland by a causeway near the Lewiston-Clarkston valley. Named after Chief Timothy (Tamootsin), a leader of the Alpowai band of the Nez Perce, the park sits on land with deep Indigenous significance — the Nez Perce lived and fished here for thousands of years before the Lewis and Clark expedition arrived in 1805.
Today the park blends recreation with culture. The “Listening Circle” — a basalt amphitheater designed by artist Maya Lin (creator of the Vietnam Veterans Memorial) — honors the Nez Perce and the Columbia River Basin ecosystem. Meanwhile, the marina, swimming beach, and campground make this a complete family destination on one of the most scenic stretches of the Snake River.

Wildlife & Nature
Chief Timothy State Park — 282 acres on an island in the Snake River near Clarkston — is named for Timothy (Tamootsin), a Nez Perce leader who befriended Lewis and Clark during their 1805 expedition. The park sits in the Alpowai Interpretive Center area, which documents the rich history of Nez Perce people in the Snake-Clearwater confluence region. The park island was created when Lower Granite Dam flooded the river valley. Osprey and bald eagles fish the reservoir. Mule deer swim to the island. Yellow-headed blackbirds nest in the marshy edges. Canada geese breed on the shoreline. Smallmouth bass, channel catfish, and crappie provide excellent warm-water fishing.
