Frenchman Coulee is a dramatic basalt-walled coulee on the Columbia Plateau—towering cliffs, volcanic columns, and scattered hoodoos create strong geometric compositions. Photograph sweeping cliff faces, textured rock, seasonal wildflowers, and climbers for scale. Best at golden hours (sunrise and sunset) when low light sculpts the basalt; spring and fall offer milder temperatures and blooms. Access from Old Vantage Hwy with roadside pullouts and small informal parking; no fee but be respectful—
