Why are there cows on the trail to Coyote Peak?
If you hiked up Rocky Ridge this month and found cattle grazing where you expected an open fire road, you weren't imagining things and you weren't lost. Santa Clara County put them there on purpose. From mid-August through November, the county pastures cattle across the Rocky Ridge and Coyote Peak Trails inside Santa Teresa County Park, the two routes locals use most for the panoramic climb above Almaden Valley. The stated reason is grassland habitat management and fire danger reduction, and the posted rules are specific: dogs stay leashed, gates stay closed, and calves that look alone are left alone, because they usually aren't.
Every hiking guide to this park describes it the same way: spring wildflowers on Stile Ranch Trail, sweeping views from the summit, minimal shade. That version isn't wrong, but it's the March-through-June version of a park that spends four months a year running as a working pasture. If you treat Santa Teresa County Park as a fixed backdrop, you'll miss the part of its calendar that's happening right now, on the exact trails you're most likely to use.
The trails split, and only two of them change
Santa Teresa County Park covers 1,673 acres in the Santa Teresa Hills and carries more than 17 miles of unpaved trail for hikers, cyclists, and equestrians. The current grazing rotation touches a small fraction of that network. Everything else runs as it does the rest of the year.
Currently shared with cattle (mid-August through November):
- Rocky Ridge Trail
- Coyote Peak Trail
Unaffected, same as always:
- Stile Ranch Trail
- Fortini Trail
- Mine Trail
- Bernal Hill Loop
That split matters more than it sounds. Rocky Ridge and Coyote Peak are the two routes that lead to the park's best-known summit view, so they carry disproportionate weekend traffic. Stile Ranch, the trail every wildflower guide points to each spring, sits on the opposite side of the park and stays open to foot traffic the entire grazing season. If your usual loop starts at the Pueblo Day Use Area and climbs straight to the peak, you're sharing the trail with livestock right now. If you usually enter from Fortini Road, you're not.
There's a small irony built into the geography here. Coyote Peak, the summit that gives Rocky Ridge Trail its reason for existing, sits just outside the park's own boundary line, technically adjacent county land rather than park acreage proper. The grazing program treats the two as one continuous grassland, which is the point of pasturing cattle here in the first place: fire fuel and habitat don't stop at a property line, so the management doesn't either.
Why cattle instead of mowers
A crew with mowers could clear the same grass in less time and with none of the fencing or leash rules. The county uses cattle anyway, which tells you the goal isn't just cutting grass short. Grazing animals work the ground differently than a blade does, breaking up thatch, cycling nutrients back into the soil, and creating the kind of patchy, uneven grassland that native plants and ground-nesting species actually depend on. It's a slower, more hands-on approach to the same fire-danger problem that drives a lot of hillside land management across the South Bay, and it's why the notice specifically flags Rocky Ridge and Coyote Peak rather than the whole park: those are the exposed, grass-heavy slopes where fuel load builds up fastest over a dry Bay Area summer.
The tradeoff for hikers is real but bounded. You'll want to keep dogs leashed and give any cattle you pass a wide, unhurried berth, and the county's own rule against approaching calves is worth taking seriously rather than as boilerplate. But the season is finite. By late fall the rotation ends, the fencing comes down, and Rocky Ridge goes back to being an open fire road until next August.
The rest of the park's current texture
Grazing season overlaps with a handful of other things that make this park more than a hiking loop, and most of them run quietly enough that even regular visitors miss them.
The Bernal-Gulnac-Joice Ranch sits inside the park as a preserved 19th-century ranch site, complete with historic farm buildings and equipment and a small flock of chickens kept on the grounds. It's open for public visits and school tours, and it's the starting point for Agents of Discovery, a free mobile scavenger-hunt game the county built to walk visitors from the ranch house out to Santa Teresa Springs while they complete challenges about the site's history and wildlife. It's available in English and Spanish, and it's the kind of low-key family activity that never shows up in a trail-conditions report but explains why a lot of Almaden families end up at this park on a Saturday that has nothing to do with hiking mileage.
The park also carries an archery range operated by the Black Mountain Bowmen Archery Club, open to the public except during scheduled tournaments, and the Santa Teresa Golf Club, an 18-hole championship course paired with a 9-hole par-three layout and a clubhouse restaurant. Neither shows up on a hiking map, but both are reasons a resident might drive to the same address for a completely different afternoon.
Getting there without a car
If you live in Almaden Valley, there's a way into this park that skips the entrance fee and the parking lot entirely. The Calero Creek Trail starts at Harry Road, runs paved for its first stretch parallel to Camden Avenue, then crosses Santa Teresa Creek on a singletrack path before reaching the park's Stile Ranch entrance. It's maintained by the City of San Jose's Parks, Recreation and Neighborhood Services department, not the county, which is a small but telling detail: the trail that feeds Almaden residents into a county park is itself a city asset, built and kept up by a different agency than the one running the grazing program on the other side of the hill. Neither jurisdiction advertises that split, but it's why the connector trail sometimes gets attention and upkeep on a different schedule than the park itself.
The crossing at Santa Teresa Creek isn't bridged, so it can mean wet feet after a rainy stretch. In September, with the creek running low, that's rarely an issue, which makes this the easier season to use the car-free route rather than driving around to the Bernal Road entrance.
What this adds up to
Santa Teresa County Park doesn't run on one season. It runs on at least three: the wildflower stretch every guide already covers, the dry, exposed summer everyone complains about, and this current four-month window where two of its most-hiked trails double as an active grazing operation. None of that shows up if you only ever check the park in March. If Rocky Ridge and Coyote Peak are your regular loop, the practical move through November is simple: keep the dog leashed, give any cattle room, and don't be surprised if the ridge feels a little different than it did in June. It's not a closure. It's just what this particular hillside does every fall.
