Oaken Grove Park is a lovely park with an extensive play area on the Marlow side of Maidenhead. There is a cafe (open at peak times), plenty of open grassland, easy free parking, a sand pit, zip wire, small trampoline and a variety of play frames/equipment suitable for toddlers, pre-schoolers and older kids. There are also tennis courts managed by Maidenhead Tennis Club 01628 623785 and a bowling green.
It takes about 10 minutes to drive there from Marlow. Access the main car park from Oaken Grove Road. It’s a bit tucked away so you wouldn’t really know its there unless you’ve visited it. View map
The park is a public space,, open I believe at all times.
