Join us onboard
We run our Discovery Boat Ride (30-minute introduction to the tunnel) most Fridays, Saturdays and some Sundays. You can book these trips below.
We have set up dates for the Through Trip Boat Ride (a one way two-hour tour along the full length of the tunnel) in 2025. Please check the website for updates.
Please note that these trips are run by volunteers, so operating days depend on availability. We will strive to operate as advertised, but occasionally at short notice we may have to cancel trips for the day due to illness or holidays.
Check out our bookings pages as during the school holidays we provide extra trips.
On time departure; Our suggested car park is located a 15-minute walk away over near Marsden Railway Station, Postcode; HD7 6DH.

For the through trips you need to register your arrival and be ready to board 15 minutes before departure times, as with the other activities taking place we must depart on time.
