I've seen this posted as an event on a couple of other groups and thought as we are a Reigate based group we should go and check the caves out. All the details posted below are details from a website I found. So have a read through and if interested feel free to come along.
Reigate is well known for its 'caves' which riddle the town centre although these are in fact old sand mines. The castle mound overlooking Reigate town centre is composed of soft sandstone and has been mined over several centuries. The castle has long gone but the mound and many of its excavations still remain.
The Wealden Cave & Mine Society is able to arrange conducted tours of Reigate's historic underground heritage, known locally as the "Reigate Caves", which include the Baron's Cave in the Castle Grounds and the East and West Caverns in Tunnel Road. Your view of Reigate will change once you have experienced what lies beneath your feet!
The Barons' Cave is believed to originate from the 11th Century and was known to exist at the same time as Reigate Castle. Local folklore has it that the barons held a secret meeting at the Barons' cave on their way to Runnymede to sign the Magna Carta.
The guided tour accompanied by one of our experienced guides lasts around 20 to 30 minutes depending on the size of the party and will be conducted with lanterns.
Details of the history and preservation of the cave will be given and your guide will be happy to answer any questions that you may have.
Tunnel Road Caves
The Tunnel Road caves have had many uses during their long existence. During your visit you can see how they were originally mined and how the different uses have changed the caves.
The guided tour of the Western Caverns accompanied by one of our experienced guides lasts around 25 to 35 minutes depending on the size of the party. The cave is well lit and the floor fairly even. Details of the cave's history will be given and your guide will be happy to answer any question that you may have.
A tour is also available for the Eastern caverns although you are free to wander as you please, you should allow an hour or so for this. The cave is well lit but the floor is uneven in places so some care must be taken. Guides will be present throughout the cave and will be pleased to assist you in any way.
