Additional information for all parties

What to wear
Both children and adults should wear clothing appropriate for the weather conditions and environment. For outdoor activities, layered clothing is best for warmth and flexibility. Footwear should be sturdy such as trainers or hiking boots. Thermal socks, gloves and hats are also good ideas and waterproofs for rain and mud. In warmer weather consider sun cream and sun hats. 

Spare clothes are a good idea as well as a bag to put dirty clothes in for the homeward journey. We don’t have group changing room facilities but toilet facilities will be available to your group for the time of your event. 

For woodland and adventurous parties, there will also be specific information to help keep you safe, for example wellies are not suitable for some activities, or you may need hair tied back.
Adverse weather
We are an outdoor activity centre and as such we encourage visitors to plan and prepare for their outdoor adventure. The majority of our activities can continue in the rain or cold weather. 

However, high winds and lightening may impact our ability to deliver you party as planned. If this is the case, we will notify you as soon as possible. We may be able to offer an alternative activity or we have to cancel or postpone your party. 
​Additional facilities, available to hire
Outside space, for example for party games or a barbecue, can be booked to extend your party.  Visit the prices page for our booking prices.
Terms and conditions
​Birthday party bookings are subject to our regular booking terms & conditions.
