You might want to check out the Playa Blanca Island Villa just a few hundred feet north of Mata Chica. They have a boat with fishing guide included when you rent the villa. Our family was able to snorkel and fish using their gear at no extra charge as often as we wanted to go. It's perfect for your anniversary. It's private setting is very romantic!
When you don't feel like cooking Mata Chica is just a few minutes stroll down the beach. Mata Chica is a cute resort with little cabanas and a beach bar. There are several really nice restaurants within walking distance of Playa Blanca Island Villa.
We stayed at Playa Blanca Island Villa the first time for our 33rd anniversary and then returned with our family the following year. Send an email to Denise at [email protected]
and ask her to send you the CD loaded with over 100 photos...it's much better than their website playablanca.biz
Where ever you decide to stay I am sure you will enjoy your stay in Belize. Happy Anniversary!
