There's a very good bus service and you must take a trip to the old capital Ciutadella (about 8 miles North). Cala N Bosch itself is a 'man-made' resort with lots of restaurants around a central marina and a lot of villa, apartment and hotel accommodation. There are 2 beaches, boat trips but it's very much in its own enclave in the far South West corner of the island and you have to travel to get anywhere else.
