Things to do in Lake Forest: Canyon Trails, Old Buildings and Big Parks
A plain guide to Lake Forest's wilderness park, historic adobe, sports park and the foothills nearby, for visitors and neighbors alike.
8 Oct 2026
Lake Forest is a family-friendly city in the Saddleback Valley, in the northern part of South Orange County. Its northeast edge rises into the foothills of the Santa Ana Mountains, so the town has two sides. One is tidy suburban streets and parks. The other is rolling wild canyon country.
Until 1991 the community was known as El Toro, which is Spanish for "the bull." The new name came from two man-made lakes and a man-made forest, and some longtime residents were not happy about the change. El Toro High School kept its name. This guide sticks to places that have been here for years and are likely to stay.
Whiting Ranch Wilderness Park
This is the biggest outdoor space in town. Whiting Ranch Wilderness Park, run by OC Parks, covers about 2,500 acres in the eastern part of the city, across Foothill Ranch and Trabuco Canyon. The land is a mix of oak woodland canyons with streamside plants, rolling grass hills, and steeper slopes of coastal sage scrub and chaparral.
It has 23 trails totaling about 17 miles. They are open to hikers, mountain bikers and horse riders. Three small streams run through the park, though they flow only part of the year. The park also holds leftovers from the days when cattle ranching was the main business here, so keep an eye out as you walk.
The best known spot is Red Rock Canyon, in the north of the park. It has cliffs of red sandstone that give the place its name. Fossils have turned up as the canyon walls slowly wear away. Red Rock Canyon and Billy Goat trails are for walkers only, with no bikes or horses.
Wildlife is a big part of the draw. The park is home to mule deer, coyotes, bobcats, gray foxes and many birds, including red-tailed hawks and the small California gnatcatcher. The park takes its name from Dwight Whiting, who bought most of the land in 1885 and later helped develop the town of El Toro.
Places to see
Heritage Hill Historical Park is a small park of old buildings that tells the story of the valley. It covers just over four acres and has four restored, furnished buildings:
The Serrano Adobe, from about 1863, a reminder of the Mexican rancho years.
The El Toro Grammar School, from 1890.
St. George's Episcopal Mission, from 1891.
The Harvey Bennett Ranch House, from 1908, which shows the era of citrus farming.
Guided tours are how most people see the insides, which helps protect the old rooms and collections. The grounds are laid out with plants from the period, and you can walk around outside on your own. Kids in third and fourth grade can join school programs on early schooling and on the Native American communities that lived here before 1769.
Lakes and a forest with a story
The two lakes that gave the city its name sit in residential neighborhoods. Homes line their shores, and neighborhood associations manage them. Each has club facilities such as pools and courts. They are part of the city's character, but they are not a visitor stop.
The eucalyptus forest is man-made too. In the early 1900s landowner Dwight Whiting planted 400 acres of eucalyptus trees near Serrano Creek as part of a lumber plan. The trees grew thick, and in the late 1960s homes were built in and around the groves.
For families
The Lake Forest Sports Park and Recreation Center opened in 2014 on 86.2 acres. It is one of the largest sports parks in Orange County, with fields and a recreation center that includes a gymnasium.
The etnies Skatepark is the largest public skatepark in the area, with more than 40,000 square feet.
Heritage Hill has a school building from 1890 that children can see on a tour.
Whiting Ranch has 23 separate trails, so families can pick a path that fits the day.
A short drive away
Lake Forest has some very wild neighbors. Limestone Canyon Regional Park lies to the north, and Trabuco Canyon and Silverado Canyon lie to the east. Santiago Canyon Road, also called County Route S18, forms the far northeast edge of the city and then crosses the Santa Ana Mountains.
Those mountains are part of the Cleveland National Forest, which covers 460,000 acres across San Diego, Riverside and Orange counties. The Trabuco Ranger District looks after most of the Santa Ana Mountains. Hiking, camping, bird watching and horseback riding are all popular there. The highest point is Santiago Peak, at 5,689 feet, which is also the highest point in Orange County.
Getting around
El Toro Road runs the whole length of the city, about 10.5 miles. Interstate 5 runs along the western edge. The Orange County Transportation Authority runs bus service, but renting a car is still the easier way to get around. The nearest Amtrak station is in Irvine, and John Wayne Airport is the closest commercial airport.
