Booking Policy

We are following ongoing Government advice on preventing the spread of COVID-19 in confined spaces. We are insisting that ALL customers wear masks whilst in the Cavern unless you have a genuine exemption. This is a matter of courtesy to your fellow customers and our staff. Please be kind & respectful.

When booking please select the number and type of tickets that you require. Then pick a date and an arrival timeslot. The time on your ticket will show when we ask you to arrive by. Your tour will start 20 minutes later. The total duration is typically 45 minutes to 1 hour after your start time. Please arrive within your timeslot so you're ready for your boat trip. If you miss your start time we may not be able to accommodate you on a later tour. REFUNDS WILL NOT BE GIVEN. If you know you will be late telephone us on 01433 623018 and we will do our best to move you to a later tour subject to availability.
