- 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.
- 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.
- 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.
- 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.
