Port Antonio is in Jamaica.
Tucked away on the eastern point of the island, Port Antonion is still relatively unknown by most tourists, but it has for years been the hideaway of royalty and stars alike. It is easy to see why. Its seclusion is what gives this town its charm. The beaches are beautiful, albeit a bit rocky. However the seclusion from throngs of other tourists is a huge payoff. The people are extremely friendly, and the whole city rings with a unique character all its own.
Port Antonio is northeast of Kingston and east of Ocho Rios. From Kingston to Port Antonio, you would have to fly into Norman Manley International Airport in Kingston and from there possibly take a cab from the airport, which would be very expensive, as it's a ~3 hour drive. You may opt to rent a car and do the drive. A third option is to get to the Central bus station in Kingston ("The Half Way Tree" bus terminal), and take a bus with the locals (ride is about 2.5 hours, with little leg room but lots of fun, expect 80's and 90's American and Jamaican soft rock songs to play on the loudspeakers), costing only 450 Jamaican (Feb 2016).
If you’re coming from Ocho Rios you can either take a cab, drive east on Highway A4/A3 or take a flight from Ocho Rios private airport.
If you are flying into the Sangster International Airport in Montego bay getting to Port Anotonio is about a 3 hour ride along the north coast. Although the journey is a bit long the scenery is wonderful.

There are many interesting things to see in Port Antonio. A “must see” is the Blue Lagoon. At this attraction, the blue lagoon is described to be a land-lock cove where different shades of blue, color the lagoon. At this spot tourists are welcome to swim in the lagoon if they wish. This spot is also known for its romantic feel, so it’s great for couples. Another hotspot is the Navy Island. This is located off the island, but a short boat ride away. Here one can enjoy its beautiful golden-sand beaches and its own tropical rainforest. Other sights to behold are classic buildings that are still much intact, such as Portland Parish Church and Portland Parish court house.
