Blue House Hole is a vivid turquoise swimming hole on the Cowlitz River framed by steep banks, exposed roots and a small abandoned blue structure—great for dramatic waterscape and environmental portraits. Best light is early morning or late afternoon for warm side light and reflections; overcast days deepen water color. Access is informal from roadside pullouts and short, sometimes muddy trails; parking limited—use a high-clearance vehicle if needed. Summer sees swimmers and anglers; always heed
