Tourists will always look for something different. Sure there will always be the usual sight-seeing, swimming and beaches but checking out nearby islands and what lies within them is another adventure waiting to be discovered. Such regions as that of Maine use the nearby islands as a part of preaching their rich tradition of promoting tourism and providing people with something worth their while.
The usual transport towards them would be through the boat rides. While people can expect another type of experience in these island settings, it would be best to get the necessary information so that they can more or less have an idea of what makes island tour hopping unique from the usual standard tour packages. Nature and roughing it in a sense, islands will provide the needed atmosphere that temporarily replaces the urban way most tourists are accustomed to. Besides, the usual recreation and activities can be done there, a lot more privately and away from the normal conservative tourist.
