Aliso and Wood Canyons Regional Park, Regional park in Laguna Niguel, California, US.

Aliso and Wood Canyons is a regional park covering approximately 4,500 acres with mature oak groves, sycamore trees, and two streams running through wooded canyons and rolling grasslands. The park includes over 30 miles of trails designed for hiking, mountain biking, and horseback riding.

The canyon was home to the Acjachemen and Tongva, whose territories met at Aliso Creek; the Acjachemen village of Niguili stood near the confluence with Sulphur Creek. The 1769 Portolá expedition was the first European party here, and the native inhabitants were later moved to Mission San Juan Capistrano. Rancho Niguel, granted to Juan Avila in 1842, passed to Lewis Moulton and Jean Pierre Daguerre in 1895. The county assembled the park from about 40 parcels, the largest a 1979 donation of 3,400 acres by the Mission Viejo Company, and it opened on March 31, 1990.

The name Aliso comes from the Spanish explorers of the 18th century, probably from the white alder (Alnus rhombifolia) along the creek; Wood Canyon takes its name from the live oaks and sycamores in the canyon. The Acjachemen and Tongva used Aliso Creek as the boundary between their territories, and the Acjachemen village of Niguili stood near the meeting of Aliso and Sulphur creeks.

Trails run about 30 miles (48 km) through Aliso, Wood and parts of Laguna Canyon, linking to Laguna Coast Wilderness Park to the north. Elevations range from 14 feet at the canyon floor to 1,036 feet at Temple Hill, called "Top of the World", on the western boundary. Carry water; canyon routes climb.

Dripping Cave in Wood Canyon sheltered Native Americans, then served as a base for the outlaw Juan Flores and his band, who robbed stagecoaches between Los Angeles and San Diego; it keeps the nickname "Robbers Cave". In the northeast, the exposed Pecton Reef, formed in the Miocene, has yielded thousands of fossils of marine animals, reptiles, birds, plankton and algae.
