사우스 케임브리지셔‬에서 가장 멋진 ‪6‬개의 천연기념물

Parking is £2. There is a portaloo and a bin in the carpark. This hike was limited in what you could see, in August the trees and weeds blocked most of the view. For safety note that the pathway takes the narrow road that cars are entering and exiting. There are two crossings over the guided path where the buses are traveling at speed. The first part of the walk by the Ouse was lovely as was the last part on a field where you ton off by the weight limited bridge. I would imagine in winter the path would be a mush pit.

Good track around the base of a hill. Some narrow parts all quite firm paths but no hedges or overhangs. Worth adding to your ride if you like not too tricky off road

The bus whizzes through the yellow grain landscape like oiled lightning. The intercity bus from Cambridge to St Ivy rolls over a special lane bus track and reaches an impressive speed. Today he transports the four of us to the "Fen Drayton Lakes Nature Reserve", in the lake landscape we hike and do "birdwatching". “Fen Drayton Lakes was originally a flooded sand and gravel pit bordering river floodplains. Today the area is a magnet for a variety of wildlife including otters, dragonflies, ducks, swans and geese. There is something to see (and hear) here all year round.” (https://www.rspb.org.uk/reserves-and-events/reserves-a-z/fen-drayton-lakes/)

Part of the RSPB Nature Reserve, Far Fen Lake is recognisable by the island near its eastern shore.

On Stow cum Quy Fen is a small rectangular pond. It is likely this is a filled in pit from the 19th century when coprolite was quarried in the area. Then a valuable fertiliser, coprolite is apparently dinosaur dug. The area is now a Site of Special Scientific Interest (SSSI).

Nature has reclaimed Coploe Hill Pit since its days used as a chalk pit. The area is now a haven for wildlife, home to many species of birds, insects and small mammals. Surrounded by rolling green fields, it's a lovely place to stop on a bike trip.

just ride past up very steep hill out of Duxford
