MINNEAPOLIS - The Twin Cities have some of the best parks in the nation.

For the second year in a row, the non-profit Trust for Public Land rated Minneapolis and St. Paul first and second in the nation for their city park systems.

The organization bases its ParkScore rankings on three factors: park access, which looks at the how many people live within a 10-minute walk (or a half-mile) of a park; also park size; and how much cities invest into facilities.

Trust for Public Land says Minneapolis scores high on all factors, with 97-percent of the city's residents living within a 10-minute walk of a park. St. Paul came in a close second on access and amenities, and only trailed because of a smaller average park size.
