Cambrian Cruisers Marina is a canal boat hire base and marina located just north of Pencelli village, roughly five miles south of Brecon, within the Brecon Beacons National Park.

Situated near the northern end of the Monmouthshire and Brecon Canal, it offers moorings and facilities for both hire boats and private craft, and serves as a popular starting point for canal holidays.

From the marina, boaters can cruise north to Brecon Basin or south toward Talybont-on-Usk, with either direction taking approximately two hours and passing notable features including the Brynich Aqueduct, lift bridges, Ashford Tunnel, and locks, all set against views of the Brecon Beacons.

The adjacent towpath also provides a three-mile walking or cycling route into Brecon.
