Runnymede Meadows & Pleasure Grounds
Runnymede is an attractive area of riverside meadows, grassland and woodland now owned by the National Trust. It is rich in flora and fauna, and has a network of lovely footpaths. The nearby Runnymede Pleasure Grounds, right on the River Thames, is a lovely park open all year and excellent for picnics. There's also a paddling pool, children's rides and facilities, open in the summer.
The Runnymede Pleasure Grounds are and a good staring point for walks. You can stroll along the river to get to the three Runnymede monuments: one to commemorate the signing of the Magna Carta, one to honour the assassinated US president, John F Kennedy and, at the top of the hill, the Air Forces Memorial.

There's a Pay & Display car park by the Pleasure Grounds, just off Windsor Road (mostly grass).
