If you fancy a trip on the water south of Gran Canaria, but not looking to spend a whole day at sea, the ferry from Arguineguin to Puerto Rico and Puerto de Mogan is your best option. The trip takes approximately one hour, so it should not take up too much of your time. You can get off the ferry and have a walk around town and then return on the ferry later in the day.
If you have planned a trip to one of the towns mentioned above, you can get a new view of the coast by travelling on the ferry. Furthermore, the coach trip to Puerto de Mogan is not that preferable (sometimes the driving can be wild).
The first ferry departs Arguineguin at 10.40 and the last ferry returns at approximately 17.15.
