This is the bonus for Adventure Lab Cache ~ Caerphilly Castle History Trail.
https://labs.geocaching.com/goto/CCHT123
You will need the Adventure Lab App on your mobile phone/device to answer questions and collect the codes from the five locations around the Castle to solve the simple puzzle below.
The stages can be done in any order but we suggest starting from the virtual ~ The Castle..... enjoy you visit any feedback on the AL is welcome.
The stages are all wheelchair accessible along a good path around the Castle...... some are just off the path you may need to go onto the grass, unfortunately this bonus is not.
When you have all the clues from the Lab cache locations the bonus cache can be found here:
