Montlake, Seattle Montlake is an affluent residential neighborhood in central Seattle. It is bounded to the north by Portage Bay and the Montlake Cut section of the Lake Washington Ship Canal, to the east by the Washington Park Arboretum, and to the south and west by Interlaken Park. Capitol Hill is on its south and west sides, and the University of Washington lies across the Montlake Cut to the north. State Route 520 runs through the northern tip of Montlake, isolating four blocks from the rest of the neighborhood. Though sports at the University of Washington are often referred to metonymically as "Montlake," UW sports facilities are not located within the traditional bounds of the neighborhood (but "are" located on Montlake Boulevard N.E., across the Montlake Cut from the neighborhood).
