You could go to ochi directly from the airport using juta or knutsford express. its 1 1/12 hrs mobay to ochi, 3 hrs return..or you could go from negril using knutsford which goes through mobay to ochi and return, bus leave at 7am and 11 am gets in 6 hrs later you are getting a view of the countryside and see some sights. i personnaly enjoy dunns falll and intend to get over there myself from negril.
