Paraiso Trail Loop

Dogs Unknown

E-Bikes Unknown

This loop can be ridden in either direction but uphill grades are somewhat easier going clockwise. The trail connects with Ohlone Trail near the golf course and the Manzanita Trail and Crystyl Ranch Trail at the top of the ridge.

Almost no shade so avoid the midday heat. Parking, restrooms and water available at Arbolado Park.

From trailhead parking across Boundary Oak Golf Course, keep left heading up the hill then turn right at the junction with the Ohlone Trail. It's a steady climb as the trail winds up the ridge on a fairly smooth fire road with a few sandy spots.

As you reach the Manzanita Trail on the left, then Crystyl Ranch Trail immediately after, there's a final steep pitch to the high point of the loop. This is a nice spot to catch your breath and enjoy the view over Diablo Valley. It's a sharp right to stay on Paraiso Trail (continuing up leads to a locked gate) and a steep descent to the Rancho Paraiso neighborhood. This section of the trail differs from the published map - which is why you should check MTBProject.

As you reach the houses, there's a connector to Arbolado Dr. but, although it's not marked or obvious, it's possible to ride along the concrete drain that runs south along the fence line. This connects to Ridgestone Ct. and a paved access road to a water supply tank. Continue south up this road and at the top veer right onto a dirt fire road as it descends along a ridgetop to another water tank.

Keep right and descend on the paved access road crossing Arbolado Dr. and continuing on the paved and gravel trail through the neighborhood past Arbolado Park and over one more hill to reach the trailhead.
