There is a bus departing from Bournemouth Coach Station, Stand K at 9:30am and 10:30am but if you are looking for the bus after this time, you will have to make your own way to our main bus stop by Bournemouth Pier.
By bus: Find Bus Stand 5 and board any of these buses: 5, 5a, 6a, 12 and purchase a ticket to Bournemouth Pier (don't forget to buy a return ticket if you need to get back to the station after your tour)
By taxi: The taxi ranks are in front of the Train Station, it should be easy to find a taxi to hop in to. Ask for Bournemouth Pier bus stop, behind the Hot Rocks Restaurant.
By Beryl bike, ebike or scooter: There are plenty of bikes and scooters to hire at the station, please see more info here: Beryl website for Bournemouth
