Here is the link which includes directions. If you look at the park map you will see Car Park 3 on the right hand side and some BBQ icons. We have booked BBQ number 4 in the corner.
Getting there is pretty easy, from the M3 J4 follow signs for Frimley, then Frimley Green. When you get to the 'Green' in Frimley Green you go right at the roundabout, past the Rose and Thistle, the road ducks under a railway line than the entrance to the park is on your left hand side. Or, put GU16 6HY into the sat-nav if you have one.
