While it is one of the more inland hikes in Morro Bay State Park, the loop formed by connecting Chumash Trail, Crespi Trail, and Hutash Trail delivers ample coastal views as it leads to a lovely grove of coast live oaks. This lollipop loop covers 2.9 miles with 420 feet of elevation change. Hutash Trail can be trimmed from the circuit to lower the round trip distance to 2.55 miles and reduce the total elevation change to 280 feet.
Begin from a dirt turnout on Turri Road, half a mile inland from South Bay Drive and just across from the meandering waters of Los Osos Creek. Spot a sign for Chumash Trail and march up an embankment into Morro Bay State Park. The trail levels out as you make your way north across a grass field. After less than a hundred yards, you will come to an unmarked split. A shortcut path parts to the right that can be used to trim off part of Chumash Trail and the opening of Crespi Trail. Continue straight on Chumash Trail to stick with the main route.
To your left, you’ll find a perspective down Los Osos Creek toward South Bay Drive. In front of you rises Cerro Carrillo, with slopes punctuated by large boulders like Tiki Rock. The trail makes its way through brush and dips across a gully before returning to open grassland.
You will have hiked less than half a mile when you come to a marked junction where the loop begins. In order to face the bay views on the second half of the loop, do yourself a favor and turn right on Crespi Trail. Tackle the circuit in a counterclockwise direction and set out east toward the oak grove.
After just a tenth of a mile on Crespi Trail, you will come to a split with no trail signs. Bypass Trail branches off to the left and omits the oak grove. Bear right to remain on Crespi Trail. A short distance after that, proceed straight through a junction with the other end of the shortcut path that you passed near the start of Chumash Trail.
Admire Hollister Peak as you make your way east across rolling grassland. Below the ridges in front of the peak, you’ll spot an oak grove. After a couple gentle rises, the trail turns downhill. Cross the bottom of a valley and slip into the oak grove, a mile from the trailhead. Pass through pools of sunlight that penetrate the canopy of massive oaks. This tucked-away grove appears to receive few visitors and is a true highlight of the hike.
Relax in the shade of this tranquil retreat and then proceed across a dry creek bed. Follow the trail through a sharp bend to the left that leads to the exit of the oak grove.
Crespi Trail heads west now, gradually ascending a grassy slope above the trail you took into the grove. At the top of this slope, the trail crosses over a notch in the terrain. Reaching the other side, you will discover delightful views west toward Morro Bay. Morro Rock will be visible rising over the north side of the bay.
Slip through sagebrush as the trail turning downhill and weaves around a draw in the terrain. Come to an important unmarked junction, 1.43 miles from the start of the hike. Hutash Trail ascends to the right, rising to higher ground with the loop’s best bay views. Hutash Trail reconnects with Crespi Trail after gaining 152 feet and descending 192 feet over 0.54 miles, replacing an easier 0.19-mile long section of Crespi Trail.
Turn right up Hutash Trail and make your way farther up the slopes of a hill on Park Ridge. Cross a 437-foot high point and weave downhill again. Enjoy the broadest views out over the tidal estuary of Morro Bay and south toward the town of Los Osos, which is backed by the mountains of Montaña de Oro State Park.
Take the second half of Hutash Trail back down to Crespi Trail. Turn right and hike west to a 4-way intersection. You will be facing the back of Portola Hill (which provides its own views over Morro Bay). Look to your right to admire Tiki Rock on Cerro Cabrillo and then turn left to hike south down Chumash Trail.
Chumash Trail goes quickly downhill and crosses a dip with bay views on your right. Make your way across gentle grassland and pass through the initial junction with Crespi Trail. Close the loop and proceed straight on Chumash Trail to return to Turri Road and complete the 2.9-mile hike.
