The village of Mahahual is already seeing tourist return. Yes, the area was hit hard. But, government agencies were very quick to respond. Major work is being done in the village to improve streets. A maelcon (oceanfront street) is being completed. Full size palm trees have been plant for several kilometers. The beach has been restored and made wider. The beach road to the south has been made wider and improved.
The cruise ship pier is scheduled to be back in service by this summer 2008. It was 75% damaged by Dean. This was the second largest cruise port on the Mexican mainland. So, I guess you could say there has been an all out effort to get the area back and running.
As for the diving:
Diving to the south of Rio Bermejo are still very good. This is the area at about 5 km south and below. Area to the north near Rio Indio show some of the damage of hurricane Dean, this was the area of landfall.
Many of the business are open or plan to open very soon. Some are offering discounts as well.
I will be down there next week. Planning on getting some diving in. Depending on weather, hope to check out Chinchorro, again.
