The main event takes place on Bank Holiday Monday, 30 May, at Worcestershire County Museum at Hartlebury Castle.
'Let's Rock!' (11am-4pm) will give visitors the chance to learn all about the types of stones used to build places such as Hartlebury Castle, as well as getting hands on with activities exploring rocks, fossils and dinosaurs.
The event, in conjunction with the Earth Heritage Trust, will be a family friendly day, full of hands on activities and things to learn. Craft activities for kids (and adults) include making your own pop up castle, creating your own badge or fridge magnet, moulding clay dinosaurs or making a snake mobile.
The Herefordshire and Worcestershire Earth Heritage Trust will be on hand to answer any questions visitors may have about rocks and fossils and visitors are welcome to bring along any finds they have to have them identified. There will also be the chance to look at different rocks and minerals through a microscope or become a mini builder with real stone blocks.
Families can also follow the 'Building Stones Trail' around the Museum to discover some fascinating facts about the building and the stones used in its construction.
And lurking in the Orchard picnic area visitors may be surprised to come across Vernon the life size Velociraptor.
As well as all this, visitors can also explore over 1,000 years of history within the Museum including a special exhibition about Hartlebury's time as a convalescent hospital during the First World War.
Hartlebury Castle's new Café, James' Kitchen, will also be serving up 'Brontosaurus Pies' and 'Mammoth Burgers' alongside their usual tasty treats.
Admission to the museum, including the event, is just £13 for a family ticket so it is great value for money for a Bank Holiday day out.
Pippa Ashmore, Events Organiser, said: "Rocks, stones, fossils and dinosaurs are fascinating subjects for people of all ages so this Bank Holiday event provides a great opportunity for a fun and educational day out for all the family, and it's great value for money too."
Following the Monday event, the fun continues with three days of dinosaur themed craft activities. On Tue 31 May, Wed 1 June and Thurs 2 June three different craft activities will be available each day including fossil imprints, Triceratops masks, Pterodactyl mobiles and dinosaur eggs. On these days the usual admission costs apply, plus £2 per child for the full day's activities.
