Mile Square Regional Park

The expansive open space is a popular spot for family gatherings and spending a day outdoors.

Originally agricultural land, Mile Square Park was converted to military airfields used or training during and after World War II. The Navy Department leased the land to the County of Orange, and the first phase of Mile Square Park opened in 1970. Phase 2 opened in 1973, and the third phase opened in 1976.

What’s At Mile Square Regional Park

Fishing Lakes

There are two fishing lakes to choose from within the park. Mile Square Regional Park is great fishing for Rainbow Trout, Largemouth Bass, Bluegill, Crappie, Catfish and Carp. Fishing is permitted in both lakes and they are stocked regularly. A fishing license is required for everyone 16 and over.

Mile Square Park hosts an annual Kids Fishing Derby for kids ages 6 to 15 to fish for free and a chance to win prizes.

The largest lake, Freedom Lake, is located near the corner of Edinger and Euclid. The smaller lake, South Lake, is located near Warner and Euclid. Freedom lake has two islands, one of which can be accessed by a pedestrian bridge to explore the path through the trees.

You can also opt to reserve a concession-operated paddle boat to cruise around on the water. The new Swan Boat rentals are operated by Wheel Fun Rentals near the large lake and can be rented for $11 per hour, per person for adults and $6 per person, per hour for kids 17 and under.

Archery Range

An archery range is available within the park with classes held regularly. The range is open to the public free of charge, from 7AM to sunset daily (closed every Thursday 7AM-11AM for maintenance). Large groups are required to make a reservation and a fee is required. There are 24 shooting lanes with targets, a shade structure for shooters with bow racks, a 20-foot safety berm, and perimeter fencing. The archery range is first come first serve, and you must bring your own equipment. Shooting lanes have varying distances to accommodate all abilities.

Nature Area

A 15-acre nature area is open daily from 7AM to 3PM. There are packed dirt trails to explore, plenty of trees, a small pond, and the opportunity to spot wildlife. The Nature Area also houses Camp Sycamore, a designated area for youth groups that offers a first-time-camping experience for kids ages 6 to 12. Camp Sycamore features restrooms, a picnic shelter, tables, barbecues, sinks, a campfire ring, an area for tents, and a security fence. A small fee is required to reserve Camp Sycamore.

Sports & Play Areas

There are many options for recreation within Mile Square Regional Park including two golf courses to choose from. Each course is regulated with 18 holes with a clubhouse that is popular for weddings. You can play a game at the volleyball courts, one of the three soccer fields, or the three baseball and three softball diamonds. A fitness par course lines 1.5 miles of the paved walking paths for those looking to add to their workout. Note that reservations are required for the soccer fields.

There are three playgrounds in Mile Square Regional Park. There is a large play area by the lake (Freedom Lake) nearest to Edinger and Euclid with a splash pad that operates during summer months, a second play area in the middle of the park, and the third is located near the smaller lake (South Lake) by Warner and Euclid.

Bike Rentals are available through Wheel Fun Rentals. The location near Edinger is open year round, and there is a second location near Warner that is open February through October. Bike options include cruisers and kids bikes, surrey cycles, and deuce coupes.
