Reservoir Canyon Trail Summit Trail Loop San Luis Obispo Hike Bowden Ranch Reservoir Canyon Open Space

If you’ve hiked up the hill east of downtown San Luis Obispo on Reservoir Canyon Trail or Summit Trail, you’ve probably pondered the prospect of connecting the two hikes in order to spend more time enjoying grand views over San Luis Obispo County. Follow Reservoir Canyon Trail up to a stone bench viewpoint, cross Ridge Trail to an old tower housing a bell, and descend Summit Trail to complete a 5.6-mile loop with 1,350 feet of elevation change.

The loop begins from a trailhead on Reservoir Canyon Road just off Highway 101 near the base of Cuesta Grade. A path to the right heads to Reservoir Creek Falls, which is easy to visit at the end of this loop. Hike straight from the parking area, going south in line with the road you drove in on. Pass through a gate crossing the road, avoiding a trail on the right that goes through a wooden chicane to reach Summit Trail and Reservoir Creek Falls. Hike straight up Reservoir Canyon Trail, which follows a former municipal road that shrinks to a conduit that is perfect for foot traffic.

The first 1.25 miles of Reservoir Canyon Trail are quite level, gaining approximately 225 feet. The effort is made easier by abundant shade from overhanging oaks, sycamores, and smaller trees that thrive along Reservoir Creek, a year-round source of water. San Luis Obispo residents relied on this water a century ago, but the canyon has retired from providing drinking water.

Cross several small wooden footbridges and come to a larger bridge to the right across the creek. Follow the trail up a fork in the canyon where you’ll sneak a glimpse over the trees toward Cuesta Grade and the Santa Lucia Mountains.

Half a mile from the bridge and approximately 1.25 miles from the start, the trail drops down to the bank of the creek. Rock hop to the other side and rise to a sharp turn to the right. The true climb on Reservoir Canyon Trail starts now, gaining 1,125 feet over the next 1.4 miles.

The sun-exposed single track ascends steadily up the side of the canyon. Be very careful as you hike up narrow segments on the trail. Trees give way to sloping grassland, which in turn give way to chest-high chaparral.

Just under half a mile from the creek, come to a peculiar collection of scrap metal sculptures that would look more at home in the Poly Canyon Design Village. These mysterious features look out of place on the mountain slope. The site is also inhabited by a grand eucalyptus tree with a swing. Cross through the camp of robotic-looking tripods toward a metal teepee at the continuation of the trail.

Press on as Reservoir Canyon Trail gets progressively steeper. Any time you need to pause and catch your breath, you’ll find views of the Santa Lucia Mountains. This is one of those trails where you will look up and think you are approaching the summit, only to discover (again and again) that the mountain extends itself just a bit farther. If the ascent appears relentless, don’t forget that excellent views are waiting from the top!

Reservoir Canyon Trail finally tapers out and reaches a small saddle north of the summit of Murray Hill (Unnamed Hill). At 2.65 miles from the trailhead, Reservoir Canyon Trail ends at a T-junction with Ridge Trail, an old jeep road along the hill’s main ridge. A short distance to the right is the top of Sydney Street Trail, which comes up from the city side of the ridge. Farther down Ridge Trail is the old tower housing the bell, which you will hike toward after visiting the nearby summit viewpoint.

Skip Ridge Trail for now and make a sharp left (at a 45-degree angle) up another single track. Stride the final 90 yards to the summit of Murray Hill. The mountaintop has a stone memorial with U-shaped benches built into the ground that made ideal places to rest your legs and take in views over Edna Valley. Look farther to the south toward Pismo Dunes and Point Sal. Find three windows of ocean views in all: Pismo Beach to the south, Whalers Island in San Luis Bay (by Avila Beach) to the southwest, and Moro Bay to the west. The panorama does not stop there. Murray Hill looks east toward the Santa Lucia Mountains and west toward the Irish Hills and several jagged Morros, including the prominently displayed Cerro San Luis and Bishop Peak.

The in-ground bench at the summit

While many locals aren’t sure what to call the summit above Reservoir Canyon Trail (unlike the other peaks around), it can be called Murray Hill, taking its name from Judge Walter Murray who resided in San Luis Obispo in the 1800s. Murray took part in the California gold rush after fighting in the Mexican-American War and wrote for the San Luis Obispo Tribune.

If you like the views and want more of the same, don’t simply hike back down Reservoir Canyon Trail. Instead, hike northwest on Ridge Trail, the old jeep road that runs past Reservoir Canyon Trail and the summit viewing area.

Walk a tenth of a mile up Ridge Trail to a junction with Sydney Street Trail, another wide dirt trail that descends to the left. Proceed on Ridge Trail as it rises over a crest. Views over Edna Valley and Islay Hill shift west toward move views of downtown San Luis Obispo, Cerro San Luis, and Bishop Peak. Over the rise after Sydney Street Trail, Ridge Trail rolls gradually downhill and delivers panoramic views.

As you continue down the ridge, an old tower comes into view. The metal tower, which is painted white on the top and red on the bottom, served as an air traffic beacon during the World War II era.

The tower stays in view until you cross a dip just before the end of the ridge where, after 3/4 of mile on Ridge Trail, you’ll pass the top of High School Hill Trail on the left. This trail provides an alternative route up to the tower, starting near San Luis Obispo High School. Hike another tenth of a mile on Ridge Trail to the tower and a junction with Summit Trail.

When you reach the tower, you’ll notice that a bell is suspended inside. Pick up a pebble and take aim. You can ring the bell by hitting it with a rock. When you’re not ringing the bell, you can enjoy a top-down perspective of downtown San Luis Obispo and gaze west toward Morros like Cerro San Luis, Bishop Peak, and Hollister Peak. The Pacific Ocean should be visible behind these volcanic plugs.

The tower at the junction of Ridge Trail and Summit Trail

Having hiked 3.55 miles to get to the tower, you can now get back to Reservoir Canyon via a 2.05-mile descent on Summit Trail. Turn right off the end of Ridge Trail, taking the single-track Summit Trail northeast from the tower.

Summit Trail descends around switchbacks that offer additional views over San Luis Obispo, the campus of Cal Poly, and nearby mountains. The trail also looks north over Highway 101 as it makes its way toward Cuesta Grade.

Bishop Peak and Hollister Peak

Peer into Reservoir Canyon as you descend around the ridge running northeast from the tower. At 1.4 miles below the tower, cross a boardwalk through a grassy flat area. Descend through more grasses and chaparral to a junction 0.4 miles below the boardwalk. Turn left to continue descending to Reservoir Canyon Trailhead.

In the loop’s final quarter mile, drop into oaks and toyon. Follow the trail down through switchbacks toward Reservoir Creek. Bear right at the bottom of the nicely defined trail and enter a riparian thicket. Cross Reservoir Creek and come to a junction. To the right, a trail connects to the start of Reservoir Canyon Trail. Turn left to take a trail downstream along a slope beside Reservoir Creek Falls.

Watch Reservoir Creek Falls cascade 30 feet into a shallow oak-shaded pool. Proceed past the waterfall to find a trail back to the trailhead parking area to complete the 5.6-mile loop.

Dogs are welcome on leashes on this hike, but mountain bikes are prohibited. No fee or permit is required to visit Reservoir Canyon, so get out and enjoy!

To get to the trailhead: From downtown San Luis Obispo, take Highway 101 north for approximately two miles to Reservoir Canyon Road (an easy-to-miss road connecting to the freeway). Turn right and drive half a mile to the trailhead parking area at road’s end. After the hike, exercise caution when getting back on the freeway.
