If you're looking to do some fishing while in town, head over to John C Land Boat Landing. It's an easily accessible, giant boat landing to go fish and enjoy some time on the water! You can also look at different areas or boat ramps around Lake Marion and Lake Moultrie!
You can visit Swan Lake Iris Gardens in Sumter, SC, a public park that is home to all species of swans. The park provides a peaceful setting with walking trails and beautiful scenery in the fall when the weather is nice.
For those who enjoy a round of golf, consider visiting Wyboo Golf Club. It's a great course and offers a fun experience!
If you're looking to explore some local nature, I highly suggest checking out the Santee National Wildlife Refuge - Cuddo Unit Entrance. You can drive through parts of the refuge on designated roads. It is a beautiful area with high chances of seeing deer, hogs, and possibly an alligator.
