Horn Park Quarry is the UK's smallest National Nature Reserve (NNR) and is recognised for its exceptional in-situ fossils, dating from the Jurassic of 170 million years ago, when this area was a warm tropical sea.

The Open Day is a chance to explore the site, speak to on-hand experts and get involved with some of the activities happening on the day, pitched at a range of ages and levels of knowledge.

Tickets are free and booked on a 45-minute timeslot basis to help us manage the flow of people throughout the day. There is a 30-minute gap between booking slots to allow cars to enter and leave the limited on-site parking bays available.

Once you've booked your timeslot, you'll receive a confirmation email with more details about how best to enjoy the day, including parking information and what to bring with you. Thank you and we look forward to welcoming you along on 31 July.
