Careful in the winter - this was pretty unrideable. Mainly grassy byway. Imagine it's super fun when dry!

Fast, straight descent with a decent surface that eases at the bottom before the T-junction. Put some watts down and you can really fly.

The cycle path along the top of the dam is wide and flat and gives great views across the reservoir. Reach it from the Visitor Centre at the northern end although access at the southern end is trickier as you have to squeeze through a narrow gap next to a locked gate by the main road.

The valve tower at Grafham Lake homes the controls that operate the opening and closing of the gates/valves allowing the reservoir water to be correctly regulated. The tower was built in the 1960s and resembles something of a spaceship!

Good cafe usually busy but plenty of space for bikes and a playpark for youngsters. Great crazy golf course due to open May 2023.

Built in the 1960s, the Valve Tower at Grafham Water is space age in design. It houses the equipment used to regulate the flow of water. The reservoir was built to accommodate a water supply for the new town of Milton Keynes.
