Porcupine Rim Trail

Porcupine Rim Trail is a mountain biking route in Sand Flats Recreation Area that winds through varying sections of smooth rock and sandy ground, alongside canyon edges. The path includes technical descents and reaches higher elevations where riders encounter different types of terrain throughout the day.

The route started as a vehicle access way to Coffee Pot Rock in earlier times. It later developed into a recreational area managed by local authorities and became popular with mountain biking enthusiasts.

The trail attracts local mountain bikers who gather here during warm months to ride and connect through their shared passion for the sport. Riders form a community that regularly uses and maintains this route.
