Showground The flat, grassed area in front of the main house is now the main staging ground for large events held in the park. It is easily able to hold the largest of circus tents and other temporary structures. When not being used for an event, this area will often contain people playing sports or picnicking with their children. The field is used for training by a number of football teams and a local Frisbee team. However the field suffers from drainage problems, meaning that it often becomes waterlogged. Teesside Small Gauge Railway Across the showground from the car park is a model engineering club with a miniature railway. It operates to the public during the summer on Sunday afternoons and on bank holidays from 1pm to 4pm. Butterfly World This building houses an environment specially controlled to allow a variety of exotic butterflies to thrive. There is a charge for entry.

There are a variety of smaller jumps nearby, as well as some rougher cycling routes. Furthermore, Quarry Wood is home to a wide spectrum of wildlife including frogs, toads, newts, foxes, rabbits and birds such as moorhen
