Three parks have their lands entirely within the Royal and Ancient Park of Toxteth.  Greenbank Park, Princes Park and Sefton Park.  All have lakes and each lake and park is fed by a different stream.  The three are different in origins and histories and are each dealt with individually.

A small part of Wavertree playground ('The Mystery') also lies within toxteth and this will be dealt with next.

The more recently created Otterspool Park lies more or less all within toxteth and will be covered a little later.  You might want to also look at Mike Royden's excellent coverage of Otterspool here.
