Frazer Park

The city of Portland, Oregon, has more than 10,000 acres (4,000 ha) of public parks and other natural areas, including one of the largest municipal parks in the United States, Forest Park. Many are managed by Portland Parks & Recreation (PP&R). One of the smallest—at 61 centimetres (24 in) in diameter—is Mill Ends Park. There are at least 279 parks and natural areas in Portland.

The development of Portland's park system was largely guided by the 1903 Olmsted Portland park plan.
