The River Blackwater in Northern Ireland forms the basis of a 23-kilometre canoe trail that flows from southwest to northeast before emptying into Lough Neagh. The trail is one of the most popular canoe routes in Northern Ireland, largely because it accommodates a wide range of paddling abilities. Access to the water is free and no licence is required.

The river's character varies considerably depending on which section is paddled. Downstream of Blackwatertown the water is slow-moving, making it well suited to beginners and families. The upper section between Maydown Bridge and Blackwatertown is more demanding: after periods of rainfall it can run at Grade 2, while prolonged dry weather can reduce it to a shallow, unnavigable channel. Numerous overhanging branches are present throughout this upper stretch, and it is not recommended for novice paddlers without qualified instruction.

Several access points allow paddlers to tailor the trip to their ability and available time. Common put-ins include Moy, Maydown Bridge, and Blackwatertown, with take-outs at Verner's Bridge, Bond's Bridge, and Coney Island on Lough Neagh. Suggested itineraries range from a 7-kilometre half-day run between Moy and Verner's Bridge to a 24-kilometre two-day journey from Maydown Bridge to Coney Island. An overnight stay at Copney Campsite makes a two-day traverse of the full trail practical. Paddling speed is estimated at around 4 kilometres per hour, and itineraries are planned to include time for breaks.

At the downstream end, the trail connects to the Lough Neagh Canoe Trail and subsequently the Lower Bann Canoe Trail to the northeast. Coney Island, located roughly 1.1 kilometres from Maghery Country Park in the southwest corner of Lough Neagh, features a motte and an ancient round tower; wild camping is permitted on the island. Shuttles are generally required for the trail, and most canoe hire providers in the area offer a shuttle service. Interpretive signage at nine marked points along the route provides information about the surrounding landscape and history.
