Location

NE Ainsworth Street
Portland, Oregon

The Ainsworth Linear Arboretum is located along 31 blocks of Northeast Ainsworth Street between Martin Luther King and 37th Avenue, where the street ends into Fernhill Park. It is a public space, available to all from the sidewalk, an amble down the median, or from your window driving down the road.

While the active city management of trees is in the public medians and parking strips of Ainsworth, many special and historic trees are in yards or around the corner on a side street. We do our best to point these trees out, as well.

Note that a wider variety of trees occurs in the blocks closest to MLK, where the trees are younger and more recently planted. These are of course much smaller.
