Hidden Creek Park East, formerly known as 53rd Avenue Community Park, is a municipal park in Hillsboro, Oregon, United States. Partially opened in 2008, the park covers 43.5 acres (17.6 ha) along northeast 53rd Avenue in the middle of the city. The park includes two multi-purpose sports fields covered with artificial turf along with basketball courts, tennis courts, and a water fountain. Its neighboring park, Hidden Creek Park West, contains an indoor recreation center which include exercise facilities and a gymnasium along with outdoor park items that include children's play equipment, a combined futsal/pickleball court, and walking trails. Plans call for a aquatics center to be built in the near future. Land for both parks were purchased from exercise equipment maker Soloflex beginning in 2001.
