Three Sisters, River islands in Potomac River, Washington D.C., US
The Three Sisters comprise three small rocky formations rising from the Potomac River waters, located west of Key Bridge in Washington D.C.
Captain John Smith first documented these islands during his 1607 expedition up the Potomac River, marking them as a notable colonial navigation point.
The islands carry a Native American legend about three Algonquian sisters who transformed into the islands after drowning while trying to save their brothers.
Visitors can explore the islands by kayak or paddleboard, though access depends on water levels as sandbars become visible during low tide.
Near the Three Sisters, the Potomac River reaches depths of 80 feet, creating an unusually deep channel compared to the typical 10-20 foot river depth.
