Phone: (626) 744-7275

Located in Pasadena between the Angeles National Forest and the Rose Bowl on the Arroyo Seco, 1300-acre Hahamongna Watershed Park provides magnificent views of the San Gabriel Mountains. The lower eastern portion of the Hahamongna Watershed Park area is currently a sediment and debris basin due to the topography of the area, and its proximity to the highly erosive San Gabriel Mountain range. It also contains Johnson Field, an inactive spreading basin, which is used for informal recreational activities, as well as a series of active spreading basins. The western portion of the Hahamongna Watershed Park Master Plan area contains the Oak Grove area (formerly Oak Grove Park). The Oak Grove area is divided into two areas, the Upper Oak Grove and the Lower Oak Grove. The Upper Oak Grove facilities include picnic facilities, restrooms, a maintenance building and the equestrian staging area. The Lower Oak Grove facilities include group picnicking area, a multi-purpose play field, rest rooms and a disc golf course.
