The area of Bayajibe is a 15 min drive from La Romana town and only 5-10 mins from La Romana airport and this is where you will find the All Inclusive resorts such as Dreams La Romana, Oasis Canoa, and the Iberostar resort.
There is also a really nice little village on the beach with a few gift shops, cafes and a public beach. The waters here are very still, clear and warm.
All the boat trips to Saona Island are from here for the toursits but you can hire a small boat to take the trip also which is a must. On the way to Saona Island there is a natural shallow where everyone gets out and stands waist high in the water for a glass of rum and it feels like you are stood in the middle if the sea and lots of starfish are to be found.
La Romana town itself it actually one of the nicer towns i have visited and i go there on a regular basis usually for the shopping at the large Jumbo supermarket which is the best place for a wide variety of fresh fruit and veg and a great place to start to equip any accommodations you eventually find.
The famous Casa de Campo is also very close as well as ALtos de Chavon a replica 16th century village made from coral, It is a beautiful place with great views of the river. Altos de Chavon also has an ampitheatre where many famous artists have performed over the years.
For me i think La Romana and Bayajibe are the nicest places in the east coast and in a perfect location, an hour and a half to Punta Cana, half an hour from San Pedron de Macoris and only 2 hours to the Capital.
The roads around La Romana seem to exceed those of other towns, especially Higuey where i live. It seems all round brighter, more colouful and cheery than where i am and not quite so mad.
