SC 802 runs in a generally southwest to northeast direction.

SC 802 travels along the entirety of Sams Point Road, beginning at the intersection of U.S. Route 21 (US 21) and US 21 Business within the city limits of Beaufort on Lady's Island.

The highway exits the city and travels through unincorporated areas for the remainder of its route.

Continuing north on the island, the highway begins to curve to the east and reaches the community of Wilkins.

With the re-routing of US 21 on February 26, 2012, the route for SC 802 was truncated to the current 6.69 miles (10.77 km).
