Los Alamitos Creek Trail Guide

The Los Alamitos Creek Trail is the most heavily used path in Almaden Valley and the spine of the neighborhood’s trail network. This paved, 4.7-mile multi-use trail follows Los Alamitos Creek from Almaden Lake Park south toward Harry Road near McKean Road, connecting residential neighborhoods to open space, parks, and schools along the way. The gentle grade, smooth pavement, and partial shade make it accessible to everyone from families with strollers to serious road cyclists.

Trail Overview

The trail surface is asphalt, wide enough for two-way traffic with room for passing. The grade stays at three percent or less throughout the entire length, making it wheelchair and stroller accessible. Riparian trees including willows, sycamores, and valley oaks line the creek corridor and provide partial shade, though some sections are exposed during midday. Benches and rest areas appear at regular intervals along the route.

The path passes through several parks and crosses under major roads via underpasses, keeping users separated from vehicle traffic for most of the route. The creek runs alongside for the full length, adding a natural soundtrack and cooling effect during warm months.

Access Points and Parking

Almaden Lake Park (north end). The primary trailhead with parking off Winfield Boulevard near Almaden Expressway. Restrooms, drinking water, and picnic areas are available. This end connects to the Lake Almaden loop trail and north to the Guadalupe River Trail.

Greystone Park (mid-trail). Accessible from Camden Avenue, this park provides additional parking, restrooms, and a playground. A popular starting point for families wanting a shorter out-and-back walk.

Pfeiffer Park. A smaller access point along the route with playground equipment and open lawn areas. Street parking is available on adjacent residential roads.

Harry Road (south end). The southern terminus near McKean Road. From here, riders and walkers can continue to Calero County Park via surface roads, though the transition involves a stretch on McKean Road without a separated path.

What You Will See

The creek corridor supports a surprising amount of wildlife for a suburban setting. Great blue herons and great egrets fish in the shallows year-round. Mallards and wood ducks nest along quieter stretches. During spring migration, the Santa Clara Valley Bird Alliance identifies this corridor as a productive birding location, with warblers, flycatchers, and swallows using the riparian canopy.

Deer occasionally appear near the southern end where the trail approaches the foothills. Red-shouldered hawks and Cooper’s hawks hunt along the creek corridor. Ground squirrels populate the open areas near Greystone Park, and their activity draws raptors for easy viewing.

The riparian vegetation itself tells a story about Almaden Valley’s hydrology. Mature valley oaks along the upper reaches give way to willows and sycamores where the water table rises closer to the surface. In spring, native wildflowers appear on the sunnier banks between trail and creek.

Popular Uses

Running and jogging. The flat, paved surface and measured distances make this the default running route for Almaden Valley residents. Many runners do out-and-back segments from Almaden Lake, with the full trail offering a 9.4-mile round trip.

Cycling. Road bikes handle the smooth pavement easily, and the trail connects to the broader San Jose bike network via the Guadalupe River Trail to the north. Cyclists heading downtown can avoid surface streets for much of the journey.

Dog walking. Dogs on leash are welcome throughout. The creek provides cooling opportunities, though owners should be aware that mercury contamination from historic mining activities means dogs should not drink from the water.

Family outings. The gentle grade and playground stops at Greystone and Pfeiffer parks make this an ideal family route. Strollers and bike trailers navigate the path without difficulty.

Trail Connections

The Los Alamitos Creek Trail connects to a broader network that extends north toward downtown San Jose. At the Almaden Lake end, the trail meets the Guadalupe River Trail southern section, which continues north to Chynoweth Avenue and eventually toward downtown via the Highway 87 bikeway. To the south, the trail connects to rural roads leading to Calero County Park and the Santa Cruz Mountain foothills.

Seasonal Notes

The trail is usable year-round. Winter rains occasionally cause creek flooding that may temporarily submerge low-lying sections, particularly near Greystone Park. The city posts closure signs when flooding occurs. Summer is the busiest season, with the trail seeing heavy use on weekend mornings. Early mornings and weekday evenings offer the most peaceful experience.
