You can select one of a few accommodations in Bayahibe itself, from where the boats leave to go to Saona.
I have stayed at Villa Iguana a couple of times (I have lots of pictures but don't have them loaded to the internet yet...they're coming! A weak album from a past stay is posted at
Villa Iguana, Bayahibe, Dominican Republic pictures from caribbean photos on webshots), which is a guesthouse/bed and breakfast. You have a key to the outside gate so you come and go like you own the place. Depending on the time of year, prices range from $30 for a walk up rate for a basic room up to $100 for the penthouse where you have a private deck and mini swimming pool, smallish bedroom, massive bathroom, but the whole floor is yours.
I have been into the Hotel Bayahibe which is more like a normal hotel with lobby and row of rooms from an external hallway. It's nice, but a bit lacking in character for my liking. They offer services like internet access, and is a bit more expensive for a similar room at Villa Iguana.
When I was last in Bayahibe in January I got word from a friend of an astounding waterside room. It has only one bed--and a fabulous hammock!--so if that would work for you it could be an option. The room I saw was the second floor of the building and it has an ultramodern sink and bathroom facilities, air-conditioning, fridge and view of the Caribbean. If you want to send me an e-mail, I can send you pictures of all the aspects of the room and how it's situated plus the sunset view which cannot be beat. It's going for 1500 pesos a night and very likely the place I'll try out the next time in the area.
All three of these accommodations are entirely walking distance from the beach where the boats depart for Saona, in fact you can watch the boats and crowds depart and return from the picture window of the last room I mentioned. My preferred tours to Saona with Seavis depart from the bigger beach further away but you need only add 2 minutes to your walk.
If you would like to see the details of anything I've experienced, send me a note and I'll happily send it on to you if it's not in Webshots yet. You can see some pictures of Bayahibe in the Villa Iguana album, but I have another at
