We stayed in Duncan's Bay 2 years ago for a few days after visiting Negril. We stayed at Jamaican Jewel which is near Silver Sands. Really enjoyed the kicked back vibe. There are a few local eateries and one local bar on the beach. One can walk to town but it will be on the road...not by the water. It is a fairly long walk but so peaceful. The town is on a hill and is quite small but is really cool. The locals are so warm and kind. No beggie, beggie. Enjoy your stay!
