Its 2 hours there and back from The Gateway. It cost £1.60 pp on the ferry, 10p pp on tax on the island, and £2.50 pp for foreigners, Indian nationals pay 10p pp. The first ferry leaves at 9.00am (the ferry service does not operate on Mondays). I visited the island in January where there was a lot of smog around the city and in the harbour and towards the island; the views of the shores are poor. The cutting into the caves is interesting for me, I would liked to of seen more history signposted and maybe a small museum of artifacts, found around the sites; as it is at time of written, neither exist. The climb to the caves and especially to the canons can be steep, and in the mornings can be slippery; wear good walking shoes. The guides will hassle you, a polite no thank you is suffice. Actually, on my trip a before disembarking onto the island, a female guide announced that she can a group of tourists at the ticket and explain the history and culture of the caves, I don't know how much she would of asked per person as a fee, I guess it would be less than what the island guides charges and her English was very. So, if that kind of guide comes up on your ferry take up the offer. I managed to see the caves and climb to Canon Hill within 1 and half hours so I was sitting on the ferry at 11:30am, the ferry left at 12:00pm. You can do more if you as there restaurants along the walk and the are hawkers selling their souvenirs and snacks and drinks. I was disappointed with the organisation of the walk and that I would of liked to seen local made products as souvenirs and gifts.
