This is one of my favorite hikes to see wildflowers in the spring. Not only is it dog-friendly, but it takes you through some of the best terrain for viewing native wildflowers. I visited a little too early this year (late March) as the peak of the bloom typically falls in mid-April. I guess I’ll have to go back.
From the main parking area, follow the short access trail to the Los Cerritos Trail. You’ll experience a short climb on the Los Cerritos Trail before reaching a pond that shares the name with the trail. When I visited, a lone duck was waddling in the pond enjoying the solitude of a fine spring morning. At the next intersection, I turned left at Peña Trail, making my way to the Serpentine Loop Trail.
The crisp spring morning offered excellent visibility and a picturesque background. The trails were wet in several locations and sported a lush green grass cover in other spots as the first 1.5 mile of the trek brought me to where the loop trail starts.
The Serpentine Loop Trail is named so for the serpentine soil found along this route. This soil offers the perfect habitat for native wildflowers and is the best place to look for them in the spring. I took the loop in a counterclockwise direction, this time not missing the Calero Bat Inn that I had overlooked during my previous hike.
The Serpentine Loop Trail descends all the way to the Cottle Trail junction, but stay left to stay on the loop trail. From this part of the trail there are several spots offering excellent views of the Calero reservoir and the Santa Cruz Mountains.
The high point, of course, was the wildflowers dotting both sides of the trails. Sure, it wasn’t a lush carpet of flowers when I visited, but the variety and colorfulness of what existed was impressive. I was able to identify California gilia, shooting star and California buttercup flowers in this stretch.
From near the Cottle Trail junction, the Serpentine Trail starts looping back and gradually gaining the elevation lost in the previous leg. You will be able to see fiddleneck and goldfields in this section as you approach a distinct spot of serpentine rocks around which you will see plenty of our state flower, California poppy.
At the Fish Camp there is a picnic bench along with an informational board explaining the self-contained ecosystem the pond provides to insects, birds and amphibians. California poppy should be visible in abundance, as are other varieties as the trail completes the 2.5 mile loop back at the intersection of Pena and Figueroa Trails.
From here, I retraced the 1.5 mile stretch along Pena, Los Cerritos and the access trails to the main parking lot. I hope people get out to experience the wildflowers first hand!

In 2009, POST purchased the 966-acre Rancho San Vicente from private developers, who had originally intended to build a luxury housing development. The ranch property is an important piece in completing a 15-mile greenbelt from Los Gatos to near Highway 101 in Morgan Hill. POST has since transferred the property to the Santa Clara County Parks and Recreation Department who incorporated it into Calero County Park in 2018.
