Chestnut Tree House

Our nominated charity is Chestnut Tree House, a wonderful children's hospice that cares for 300 children and young adults from 0-19 years of age.

At Knockhatch Adventure Park we dedicate two days a year to raise funds. Last year we also hosted two evenings with Hailsham FM. It was a privilege to provide a VIP experience for Chestnut Tree House families & team.

In 2019 we were delighted & humbled to receive an award on behalf of all our customers who have generously donated during their visit to Knockhatch Adventure Park.

Due to the high demand for prizes for different events we decided to nominate a charity that we fundraise for and donate to annually. It is therefore with regret that we are unable to support fundraising events for other charities with complimentary tickets, donations or merchandise.
