Mill Ends Park is a small urban park located in Portland, Oregon. It is known for being the world's smallest park, measuring only two feet in diameter. Despite its small size, there are several good reasons to visit including its unique history and quirky charm.

There are several interesting points of interest to see within the park, including the miniature Ferris wheel, a small swimming pool, and a tiny statue of Patrick O'Toole, the park's unofficial mascot. Visitors can also enjoy the park's beautiful flowers and greenery, which are well-maintained year-round by the Portland Parks and Recreation department.

One interesting fact about Mill Ends Park is that it was created in 1948 when a hole in the street was left vacant after a utility pole was removed. A local journalist, Dick Fagan, planted flowers in the hole and declared it a park, later naming it after his newspaper column "Mill Ends."

The best time of year to visit Mill Ends Park is during the spring and summer months when the flowers are in full bloom. However, the park is open year-round and can be enjoyed in any season.

Overall, Mill Ends Park is a unique and charming destination in the heart of Portland, Oregon, and is definitely worth a visit for anyone looking for a quirky and offbeat experience.
