Roses harbour is located at the far east of the Roses bay, at the start of the Creus cape and a few metres from the town. It provides good protection from the winds, which in this area may blow very strongly.It was originally a fishing harbour, but over time the marina area has gradually become more important, particularly after the extension and refurbishment work in 2004. The entrance channel is very wide, at 70 metres and a depth of 9 metres. The depth of the harbour ranges from 3 and 6 metres.
The marina dock is in the northern part of the harbour facilities. It has 483 moorings for crafts of up to 45 metres long, 110 of which are for visitors. The berths are equipped with water, electricity and Wi-Fi connection.
