Play in a muddy kitchen, learn 100 things to do with a stick, and make new friends at Cassiobury Park Explorers' free activity sessions for two to five year olds every Thursday.

Children should wear suitable clothing for mud and must be accompanied by a grown-up. Any younger siblings are welcome along.

The sessions will take place come rain or shine every Thursday from April 23 to July 16, from 12.30pm until 2pm (except in the May half term).

Explorers should meet at 12.30pm by the Rustic Bridge, at the Langley Way entrance.

The sessions are free, but booking is recommended.
