The New River originates in the Apalachicola National Forest in Liberty County and flows southward through Tate's Hell State Forest before emptying into the Carrabelle River in Franklin County. This blackwater stream winds approximately 25 miles through remote swampland, creating one of the most primitive paddling experiences in North Florida. The river loses its defined channel in the Mud Swamp/New River Wilderness area, dividing into multiple twisting channels that challenge even experienced navigators.

Paddling opportunities exist primarily in the lower reaches below the Mud Swamp/New River Wilderness, accessible from the southern boundary of Apalachicola National Forest. The river features numerous twisted cypress and tupelo gum trees, with water levels fluctuating considerably throughout the year. Multiple primitive campsites managed by Tate's Hell State Forest line portions of the river, available by reservation.

The main put-in points include where New River crosses Forest Highway 13 and along Forest Road 182. A concrete boat ramp at Sumatra Primitive Campsites provides access approximately 10 miles east of Sumatra, requiring a 30-minute drive along dirt roads subject to extreme weather conditions.

This river demands intermediate to advanced paddling skills due to unpredictable water levels, absence of clear channels in upper sections, and potential for becoming disoriented in the swamp's maze-like tributaries. GPS navigation is essential. Drought conditions can render portions nearly impassable, while high water opens additional side channels for exploration. No stream gauge readings are available, requiring visual inspection before trips.

Spring and fall offer the most reliable water levels and comfortable temperatures. Summer brings intense heat, humidity, and aggressive insects. Winter paddling is possible but water levels may be problematic.

The river flows through the 200,000-acre Tate's Hell State Forest, supporting black bears, alligators, wading birds, and diverse aquatic species. The forest's name derives from local legend about Cebe Tate, who became lost in the swamp.

Access is limited to Forest Service roads and Tate's Hell State Forest facilities. The nearest town is Carrabelle in Franklin County, offering basic services and the Tate's Hell State Forest headquarters at 290 Airport Road. Sumatra in Liberty County provides the closest access to upper river sections.

Safety considerations include the genuine possibility of disorientation in the wilderness area, presence of venomous snakes and alligators, lack of cell phone coverage, and limited rescue access. Permits are not required, but campsites must be reserved through the Florida Forest Service. Multi-day trips are feasible using the primitive campsites, though paddlers should contact the Apalachicola Ranger District Office in Bristol before attempting extended journeys through this genuinely wild waterway.
