坐船从那不勒斯码头到卡布里岛，怎么游览蓝洞

关于去蓝洞坐巴士的方案，在Capri.net上有详细的说明

Visitors who decide to travel by public transport can board buses to Anacapri (the island's second town) in Marina Grande (the direct Marina Grande-Anacapri bus runs to coincide with a number of the ferry arrivals), or in the center of Capri (the main bus station is situated close to the funicular railway station and the Piazzetta). Once in Anacapri, they should get off at the stop near the "Cimiterio" (cemetery), from where buses to the Grotta Azzurra and the Faro (lighthouse) at Punta Carena depart. During the summer season, buses run approximately every 20 minutes.

In the parking area close to the Grotta Azzurra (the main bus stop for buses to and from Anacapri), there is a flight of steps which lead to the mouth of the cave. Here, visitors will need to pay the entrance ticket, which includes the boat ride into the cave.

从那不勒斯到卡普里岛，游览蓝洞有两种方式：
一个是在码头直接换乘去蓝洞的快艇，到了蓝洞后换手划小船入洞；
另外一种是搭乘巴士前往蓝洞上的山崖上，下台阶到海边，排队上船进蓝洞。
后者用时比较少，还省钱。
