Currently there is no access to Tunnel top cave in the Swansea Valley due to problems with the gate. Repairs will be carried out in the near future.

Hi All. Without trying to start World War 3 on cave gates. I'm after information on combination locks for existing gates please. Have you used these before? Are they easy to use? are, were, they durable? And did they require excessive maintenance schedules? Thanks in advance for any assistance.
