Poly Canyon
What is Poly Canyon?
Poly Canyon is a 9-acre outdoor laboratory where Cal Poly students have been building experimental structures since 1963. Just a mile from campus, it's home to over 30 unique architectural projects, ranging from innovative housing models to experimental bridges. The canyon sits within one of California's most complex geological regions, where volcanic basalt meets serpentine rock, creating a challenging and dynamic building environment.
These aren't just display pieces. Each structure was designed and built by students testing new ideas in real-world conditions. The projects showcase everything from sustainable design principles to experimental construction techniques, with some using innovative materials like post-tensioned steel and sprayed concrete. Some projects succeeded brilliantly, while others showed why certain ideas stayed theoretical – both outcomes equally valuable for learning.

How do I get there?
Access the area by walking along Poly Canyon Road on campus. The interactive map below shows the route, or use AllTrails and Google Maps for detailed directions.
Choose your path - hike, bike, or run. The trail is well-marked and takes about 20 minutes to walk from campus. The wide, gently sloping road makes it perfect for mountain biking, while runners enjoy the moderate incline for training. During the day, you'll be treated to sweeping views of rolling hills and coastal mountains, while clear nights offer excellent stargazing opportunities away from city lights. It's equally rewarding as a quick architectural tour or a longer nature expedition.
Before You Go:
- 🌞 Visit during daylight hours for the best experience - structures are most photogenic in morning or late afternoon light
- 🏞️ Watch for wildlife and horses - keep your distance and respect their space. You might spot deer, hawks, and various native bird species
- 👟 Bring water and wear hiking shoes - the terrain can be uneven, especially when exploring around structures
- 🌡️ Check the weather before you go - the canyon can get hot during summer afternoons and muddy after rain
- 📱 Download the app before your visit - cell service can be spotty in some areas of the canyon
