Machado Lake is one of the few remaining natural freshwater lakes in the Los Angeles basin.
The park was formerly known as Harbor Regional Park before being renamed to honor Ken Malloy, a local community leader.
It features one of the oldest established disc golf courses in the Los Angeles area.
Restoration projects have successfully reintroduced native vegetation, including arroyo willows and mule fat, to the lake's banks.
The marsh area is recognized as a vital nursery for various fish species and amphibians.
Ken Malloy Harbor Regional Park is a 290-acre urban wilderness area anchored by a significant 45-acre freshwater marsh known as Machado Lake. The park serves as a critical stopover point for migratory birds along the Pacific Flyway. Visitors can access a network of paved and dirt trails that wind through riparian habitats and around the lake perimeter. Recreational facilities include a dedicated children’s playground, an 18-hole disc golf course, and multiple sports fields. Recent restoration efforts have focused on improving water quality and expanding native plant populations to bolster the local ecosystem. The site provides views of the Palos Verdes Peninsula and is adjacent to industrial and residential zones of Harbor City. Pedestrian bridges offer elevated vantage points for birdwatching and observing aquatic life. The park remains one of the largest green spaces in the South Bay region of Los Angeles.

Bring binoculars if you plan to visit the marsh area, as bird activity is highest in the early morning.
Check the park's status before visiting after heavy rainfall, as trail sections near the lake are prone to temporary flooding.
Apply sunscreen and wear a hat, as much of the trail system is exposed with limited canopy cover.
Do not feed the wildlife, especially the resident bird and waterfowl populations, as it disrupts their natural diet and behavior.
Stay on marked trails to protect sensitive wetland habitat; leash requirements for dogs are strictly enforced throughout the park.
