Southern Ohio Mountain Biking Association (SOMBA) is a community organization promoting responsible mountain biking that works to bring local trails to Portsmouth, Ohio. A collective of like-minded individuals advocating for building, maintaining, and preserving access to quality, sustainable. single-track trails in Southern Ohio. Fostering an environment of community pride, epic rides, and an opportunity to give back through volunteerism, SOMBA epitomizes environmentally-minded tourism.

Since SOMBA built the 6 mountain trails in and around Shawnee State Park, they have become a huge hit with not only our local bikers, but many visitors coming to our area.
