At the heart of Vilamoura is the marina which has the capacity to berth over 1,000 vessels. The marina is surrounded by large Hotels and Luxury holiday homes as well as a large casino and numerous restaurants and vibrant bars. At the far corner of the marina, it is possible to charter boats for big game fishing. There are also facilities for jet skiing and parascending. Close by there are also a number of sports clubs, a shooting range and many night clubs. Tourism in Vilamoura is extensive and well-developed, with many different resorts with ratings from 3 star to 5 star. This is a substantially higher average than the surrounding areas, which have ratings varying from 2 star to 4 star. As a consequence of being mostly privately owned, the town is very opulently designed. The town/marina has an extensive variety of activities which are usually on Tuesdays, Thursdays and weekends. Activities include touring the local caves along the coastline (which are nearer to Albufeira than they are to Vilamoura). This cave tour is usually done on tour boats. The area also has two companies which operate trains-on-wheels for travel between resorts. For the avid historians there is a preserved Roman Site and Museum providing an insight to the area's past. Originally a Roman fishing town, the ruins include baths in which the mariners used to bathe.
