This is the lake at Black Park just north of Slough. This country park has miles of trails to follow which you can negotiate with a buggy or pram or children on bikes and scooters and there are toilets ! Great when the weather is dry but maybe not so sunny. A real alternative to pricy National Trust entry. Not so good is the 2.50 parking fee during the week which rises to 3.50. You have to pay it otherwise you get a ticket, this has happened to us so be warned !
