Sumter National Fores
Martinez locals enjoy the convenience of city living while never keeping nature too far away thanks to Sumter National Forest. Just north of Martinez and across the Savannah River, Sumter National Forest is a gigantic swath of protected land where you can get into all sorts of outdoor fun. You can hit the trails at the Forks Area Trail System for a little mountain biking or head to the Strom Thurmond Reservoir for some fun on the water. Hickory Knob State Resort Park on the southwest of the forest offers cabins for rent along with many other recreational activities as well.
