The entrance to Taj Mahal is located on the west side of Highway 307, five and a half kilometers south of Puerto Adventuras. The cave itself is quite a drive back from the highway, with lots of ups and downs. Nevertheless, rental cars and other vehicles can make it without difficulty.The main entrance to the system is a circular cenote, with stairs leading to an island in the center. Cave passageways radiate outward in all directions; the main passageway (denoted by a gold line) is directly opposite the parking area. It is possible to make numerous trips to Taj Mahal and never start out on the same line twice.One of the longest possible dives is simply to take the main line to its conclusion at Cenote Vista Bonita. In the process, you will pass over breakdown piles consisting of huge boulders, and through one of the region’s single largest cave rooms. It is also possible to get to Vista Bonita by taking an offshoot tunnel that shortcuts much of this swim.
