The six-mile-long Big Laguna Trail, high in the Laguna Mountains, wends its scenic way over gently rolling hills and grassy dales, never dipping below 5400 feet of elevation nor rising to more than 5900 feet. By combining the Big Laguna Trail (BLT) with a four-mile segment of the Pacific Crest Trail (PCT) as mapped here, you'll complete a loop hike of ten miles with lots of varied scenery. This year's late El Niño snow and rain have kept the Lagunas green far longer than usual. The peak of vernal splendor along these trails may well be occurring right now.
Mountain bikers can use the Big Laguna Trail portion of the route described below, but bikes are prohibited on all parts of the PCT (the PCT is reserved for hikers, horses, and dogs). On a bike, however, you could close and shorten the loop by riding on Sunrise Highway.
You may start at the Penny Pines parking area, mile 27.3 on Sunrise Highway, about four miles north of the village of Mount Laguna. Head west on the Noble Canyon Trail. After 0.1 mile, veer left on the BLT. After another 0.8 mile through open pine and oak woods, the BLT turns south to skirt the margin of Laguna Meadow. By 2.5 miles into the hike, you'll be opposite Big Laguna Lake, its shoreline soggy and its surface brimming.
Next, the trail turns east toward an arm of Laguna Meadow that contains Little Laguna Lake. When you reach a wire fence at 2.8 miles, don't go through the gap in the fence. Instead, turn abruptly right and follow the fenceline over to the wooded area on the meadow's east side. A spur trail branches left toward Laguna Campground, where water is available if you need it.
The main trail continues south along the meadow edge and then east to follow a shallow ravine. After a turn to the north and a short bit of steep climbing, you cross the graded Los Huecos Road (4.5 miles) and hook up with an old roadbed going east and later north. You ascend easily through chaparral highlighted by blooming ceanothus, or wild lilac.
When the old roadbed makes a hairpin turn to the right (at 5.0 miles), stay left on the footpath that continues through a gap in a wire fence. The path curls down through more pine and oak woods, crosses Sunrise Highway, and continues east, uphill, to join the PCT at 6.0 miles. Turn left there and return to your starting point by way of a rambling but scenic stretch of the PCT that follows the eastern escarpment of the Lagunas overlooking the Anza-Borrego Desert.
