Somebody asked what were the main festivities in Puerto Rico, I can not find the particular question so I started a thread.
There are so many but 3 in particular:
1) Christmas Dec 25
2) New Years
3) 3 Kings day (wise men) Jan 6
However those holidays start after thanksgiving and last until Mid January (octavitas, 8 days past Jan 6)
We have many other festivities, as a matter of fact every town has its own, also basically there is sometime of celebration year round. Any excuse for a party, including the dog birthday.
We have catholic and pagan celebrations and many town festivals.
Here are some links:

Plenty of forests, lakes, waterfalls, river pools, rainforest and over 250 miles of beaches, all of them free.
