Grebe Canal Cruises Ltd. are a long established pleasure boating business (located just outside Tring in the village of Pitstone) on the Grand Union Canal. Here, the Canal meanders, unmolested by the rigours of 21st Century Life, through some of Englands finest countryside as it struggles to climb from Leighton Buzzard to Bulbourne, along the famous Tring summit, before dropping on it's long slow onward southward journey to London. Private charter party bookings, public canal trips, self steer.
