Foothill Regional Park is located in east Windsor, in the foothills of the Mayacamas Mountains. A former ranch, the 211 acres feature beautiful oak woodlands on rolling hillsides, scenic overlooks central Sonoma County, three ponds for bass and bluegill fishing, grassy meadows, and spring wildflowers.

Nearly 7 miles of trails cover varied terrain, offering easy to strenuous hiking options. Some trails are open to hikers only while others are available to equestrians and cyclists as well. Trails range from uneven single-track to wide ranch roads. One gravel trail is moderately accessible for visitors in wheelchairs.

Foothill Regional Park offers 6.8 miles of trails that vary from the challenging climb up Alta Vista Trail to the easy stroll along the moderately accessible Three Lakes Trail. Westwood and Oakwood Trails feature beautiful woods of oaks and other trees and excellent views of Windsor and the Coast Range. Picnic tables and benches are located throughout the park.

The following trails are for hiking only: Bobcat Trail, Pond A Loop, Pond B Loop, Pond C Trail, and the Ravine Trail. Other trails are open to hikers, equestrians and cyclists.

Park Notes

  • Foothill Regional Park in northeast Windsor is a former cattle ranch in the foothills of the Mayacamas Mountains. The landscape features dense oaks, sweeping view of Windsor, fishing ponds, and spring wildflowers.
  • Easy walking distance from several Windsor neighborhoods. Popular with dog walkers, families, trail runners, mountain bikers and equestrians.
  • Restroom and drinking fountain in the parking lot.

Trail Notes:

  • Nearly 7 miles of trails. Terrain ranges from a strenuous climb up Alta Vista Trail from Pond C to a gentle stroll along Three Lakes Trail. The Westwood and Oakwood trails offer beautiful views.
  • This suggested loop follows the park perimeter via several connecting trails. The route winds through oaks scattered with bay, madrone and buckeye trees. You’ll pass fishing ponds on the last leg. The loop can be extended on connecting, interior trails.

Trail Directions

  • From the parking lot, enter the park and take a quick left onto the Westside Trail. Head up an incline and follow the trail along the northern edge of the park.
  • You’ll reach the junction with the Oakwood Trail at .44-mile. Follow Oakwood Trail to the left through dense oaks, paralleling a canyon.
  • At 1.49 miles, you’ll reach the junction with the Alta Vista Trail. Follow the Alta Vista Trail to the left. (There is a split-rail fence near this junction.) This section is a sustained climb on uneven ground.
  • After you’ve reached the highest point of Alta Vista Trail (660 feet), take a short break to admire the southeastern views and then continue on Alta Vista Trail down into the park. The immediate descent is rather steep with lots of rocks, so take your time and watch your footing.
  • At Pond C, you’ll continue straight on Three Lakes Trail to the parking lot.

Driving Directions

  • From Highway 101, exit at Arata Lane in north Windsor.
  • Drive east on Arata Lane for 1.3 miles to the park entrance on your left.
  • Parking $7 or free for Regional Parks members.

Three Lakes Trail is a gravel, wheelchair-accessible trail with an accessible parking lot and picnic area. To reach the accessible parking lot, visitors need a gate card that can be obtained at no cost at Regional Parks' office at 2300 County Center Drive, Suite 120A, in Santa Rosa during regular business hours. (Please bring a photo ID and a DMV disabled plate/placard registration.) Call (707) 565-2041 for information.
