Poly Canyon and Architecture Graveyard Loop

The full Poly Canyon and Architecture Graveyard Loop is about 10 kilometers (6.2 miles) long and generally takes around 2 hours and 55 minutes to complete. This duration can vary based on your pace and how much time you spend exploring the unique structures.

While the full loop is rated as moderate due to some challenging uphill sections with inclines up to 22%, the first mile or so along Poly Canyon Road is relatively flat and easy. Beginners can enjoy an easier out-and-back hike by turning around before the steeper portions. The Cal Poly Architecture Graveyard itself is considered an easy section to explore.

The trail is located on the Cal Poly campus in San Luis Obispo. Parking is available on campus, though specific parking regulations and fees may apply depending on the day and time. It's advisable to check Cal Poly's visitor parking information before your visit.

Yes, the Poly Canyon trails are generally dog-friendly. However, it's always best to keep your dog on a leash, especially since you might encounter cattle grazing in some areas, and to ensure the safety and enjoyment of all trail users.

Spring is an excellent time to visit when wildflowers are blooming and the hills are green. Fall and winter also offer pleasant hiking conditions. It's best to avoid the trail for a few days after significant rain, as sections can become muddy and rutted. Summer can be hot, especially in the shadeless, open sections, so an early morning hike is recommended then.

No, there are no specific permits or entrance fees required to access the Poly Canyon trails or the Architecture Graveyard. However, if you park on the Cal Poly campus, standard campus parking fees may apply.

The trail offers diverse terrain. You'll find wide dirt paths, including Poly Canyon Road, and narrower single-track sections. The initial part of the canyon provides shade from eucalyptus and sycamore trees, while later sections open up to shadeless, rolling hills through grasslands. Be prepared for some challenging uphill climbs and potential mud after rain.

The most notable feature is the Cal Poly Architecture Graveyard, an open-air museum of experimental student-built structures. You'll also find the Serenity Swing Outlook, offering panoramic views, and enjoy glimpses of Bishop Peak and its rocky outcroppings.

Yes, the route utilizes sections of several official trails. You'll hike along Poly Canyon Road, and also pass through parts of Tough and Dirty Slide, Creekside, Pin it You Fairy Part 2, Pin it You Fairy, Yucca Ridge Trail, Techtite Bridge, Quercus Trail, Timber Truss Bridge, Via Carta, and Bob's Trail.

Given the varied terrain and potential for sun exposure, we recommend bringing plenty of water, sun protection (hat, sunscreen), and sturdy hiking shoes. If hiking after rain, be prepared for muddy conditions. A map or GPS device is also helpful for navigating the various intersecting paths.

Beyond the well-known Serenity Swing Outlook, keep an eye out for various student-built structures within the Architecture Graveyard that offer unique photo opportunities. The trail also provides stunning views of the surrounding foothills and Bishop Peak, especially from higher elevations.
