Forest Park can be accessed from various locations; from downtown, travel w. on Burnside St., turn n. on N.W. 23rd Ave., then w. on N.W. Thurman St. Limited street parking is available at the end of Thurman St., where a short uphill walk leads to the southern terminus of Leif Ericson Dr., the park's main walking path. Considered one of the largest forested natural areas within a designated city limit in the United States, this natural woodland contains conifers and deciduous trees, countless ridges and ravines, and a dense undergrowth of shrubs and native plants. It extends more than 5,150 acres along the Willamette River in northwestern Portland.
Leif Ericson Drive, an 11.2-mile-long well-maintained gravel/dirt path with gentle grades, is the primary route through the park; a number of small trails branch off, together creating an extensive trail network of more than 70 miles.
