About
Overview

The campground is also near Jackson Lake for easy access to fishing, canoeing and swimming.
Recreation
Swim or canoe in the refreshing waters of Jackson Lake, the only lake near Wrightwood. The lake is stocked with trout and bluegills. Powerboating is not permitted in the lake, so the setting is peaceful and quiet.

A camp host is on-site, offering firewood for sale.
Natural Features
At an elevation of 6,400 feet, Mountain Oak is shaded by oak, ponderosa and sugar pines in the Angeles National Forest. This forest, spanning across most of the San Gabriel Mountains, provides a striking backdrop for the Los Angeles area.
Jackson Lake spans just 3 acres and lies in the San Gabriel Mountains. Formed by the San Andreas fault, the lake is primarily fed by snow runoff from the mountains and is hugged by grass and sand beaches. The lake is ideal for listening to nature's soundtrack, complete with sounds of birds singing and leaves rustling in mountain breezes.
A diverse variety of animal life exists in Angeles National Forest, such as bobcat, mountain lion, bear and Nelson bighorn sheep. Many species of birds and smaller
animals also inhabit the forest.
Nearby Attractions
The Angeles Crest Highway, part of California State Route 2, is a scenic byway that meanders through oak thickets, chaparral, high desert landscapes and pine tree forests.
The ski resort town of Wrightwood is very close by. Restaurants and a disc golf course can be found at the North Resort.
Take a hike on the Blue Ridge Trail or the Pacific Crest Trail. The Pacific Crest Trail is an impressive path that starts in Mexico and zigzags its way through Angeles and continues north across California, Oregon and Washington.
