An interesting chain of conical volcanoes, or volcanic plugs called the Morros, graces San Luis Obispo County. Terrace Hill is one of the smaller and harder to identify Morros within the city of San Luis Obispo County. Unlike the other Morros, Terrace Hill has a broad flat summit. The top of the hill was removed for use as construction material in the 1920s, leaving behind a flat mesa-like mountaintop. After being considered for its own development, Terrace Hill was set aside as a 23-acre open space. A loop trail goes around the edges of the flat mountaintop, offering great views over the city and its surrounding peaks, mountain ranges, and valleys. A dirt road accessing Terrace Hill Loop facilitites a hike up around the loop and back that is 0.55 miles long with 110 feet of elevation change.
The entrance to Terrace Hill Open Space is located on Bishop Street, southeast of downtown San Luis Obispo. Parking is not available on Bishop Street, but can be found 100 yards away on Augusta Street. Pass through the gate and enter the park at the bottom of a wide dirt road.
Hike up this access road, which curves to the left before swinging back to the right. Informal paths break off from the main route and can be used for additional exploring. On the hike up, look over your shoulder for views east toward Murray Hill and the Santa Lucia Mountains, the region’s main mountain range. Leaving an area of brush you will rise to new views to the south and east. The appropriately named South Hills lie to the south, with grasses covering uneven serpentine soils. The Railroad District of San Luis Obispo is below the hill to the east, where you’ll see the Amtrak Station and may even hear arriving trains.
Proceed up the access road to a T-junction with Terrace Hill Loop, a dirt single track that tours the flat summit. On the left side of this junction, which is just 0.14 miles from the start, you’ll find a shade-casting oak and a bench. Benches are placed around the top of Terrace Hill, allowing visitors to relax as they absorb multiple views. The top of Terrace Hill is almost completely flat. It is covered in grasses as well as a few oaks and boulders.
On the north side of Terrace Hill Loop, across from the access road you took up to the mountain top, you’ll find a spur leading a short distance out and slightly downhill to an outcropping on the north side of the hill that offers a nice perspective toward downtown San Luis Obispo and Cal Poly. Skipping this spur will shorten the hike from 0.55 miles to half a mile round trip.
Continue around the loop, looking over the east end of San Luis Obispo. Islay Hill and Edna Valley will come into view to the southeast as the trail weaves between a few oaks to return to the junction with the access road. Turn left to descend the way you came up.
This hike on Terrace Hill is just 0.55 miles long with 110 feet of elevation between the trailhead and the flat mountaintop.
