The Crana River is a 12km spate river in County Donegal, flowing from Slieve Snaght and the Eskaheen Mountains into Lough Swilly north of Buncrana. As a spate river, water levels are directly dependent on rainfall, and the river runs best after significant precipitation. The town of Buncrana serves as the primary hub for accessing the river.

The Crana offers a range of whitewater suitable for paddlers of varying skill levels. The river includes a Grade 4 rapid known as "The Claw," which is considered the standout feature of the run, along with a Grade 3 section and easier stretches that accommodate intermediate and improver-level paddlers. This variety of gradient makes the river accessible to a broad range of whitewater experience levels, though the Grade 4 section demands solid technical skills.

The river has been the venue for CranaFest, an annual two-day kayaking event that has been running for well over a decade and draws participants from Ireland, the UK, and Europe. The event has historically taken place in October, which suggests that autumn, following seasonal rainfall, is a productive time to paddle the Crana. Disciplines at the event have included kayak cross racing and team racing formats across the different river sections.

The river flows into the sea at Buncrana, and the lower reaches transition toward tidal influence near Lough Swilly. The Crana is also a recognized salmon and sea trout fishery managed by the Buncrana Angling Association, so paddlers should be aware that angling activity may be present on the river, particularly during the fishing season which runs from March through September.
