Exploring Sigma: What to See

Sigma is home to some interesting places. The Back Bay National Wildlife Refuge has its main office here on Sandbridge Road. This refuge is a special place that protects wildlife and their homes.

Across the street from the refuge, you can find a beautiful garden. It's filled with American Lotus flowers, which are native to this area. This garden is located along a small stream that connects to the Currituck Sound.

Two well-known spots in the Sigma area are Tabernacle United Methodist Church and Margie and Ray's Crabhouse. These places are important parts of the local community.
