Ever wondered what Colchester Castle is like after dark? Now’s your chance to find out! Meet the mighty Juliasaurus and join us for a roar‑some dinosaur sleepover inside the castle. Pitch your campsite, meet our rangers, uncover hidden areas, and dive into hands‑on dinosaur activities. Wind down with a cup of hot chocolate before drifting off, then wake up to a light breakfast to start the day
“The activities before bed were great; sleeping in the prison was amazing. We all had lots of fun, the staff were brilliant! Thank you!”
This event is suitable for ages 5+; an adult must accompany all children.

Some of our activities may include tours using the stairs. Due to the age of our building, there are no lifts available to some areas of the castle. If you have any physical accessibility needs, please contact us on 01206 282939 so we can make suitable adjustments.
We cannot allow inflatable mattresses or camping beds of any kind (unless for medical reasons). Attendees have to bring all of their own sleeping equipment.
