To get to Montego, one must first travel from Oren in the direction of the ocean. Once you find a castle with green flags, travel behind it for about 50 blocks or so. Make a sharp right and keep heading along this path for awhile. Soon you will see a wooden tower with glowstone on top of it. This is your beacon and Montego will be hard to miss. A cobblestone wall surrounds the city. Good luck, traveler and I hope to see you soon. P.S. A road will be constructed soon to make travel easier.
