puerto rico: We are going Friday, for a cruise but we are staying in Puerto rico for a day before we get on the boat.|||Its too bad you dont have more time because PR has way too many things to see. Are you staying overnight or just for the day? If you stay for the day def go to Viejo San Juan (old san Juan) & walk the cobblestone streets & see the old spanish colonial homes. There are many unique boutiques on these streets & great shopping. There are also restaraunts where you can taste the delicious authentic food. You can see the governors palace & the old cathedrals. & definitely go to 'El Morro' its an ancient spanish warfort overlooking the ocean. Its gorgeous & a must see. If you have a few hours you can do a 'walking tour' or if you can take a bus tour to 'El Yunque' rain forest. Its 45 minutes away, so you would need a few good hours. But its nice to see. You can walk the trails down to la mina waterfalls & swim in it. Very refreshing! & if you have the night to spend you can go to the bioluminescent lagoon, near the rain forest. PR has the 3 best biobays in the world (of only 5). This one is called La Laguna grande in Fajardo. Its cool b/c the water glows in the dark when u touch it. Amazing!|||Old Town, some of the nice beaches and definitely El Morro castle. One day won't give you much time. The rain forest would require more time|||well The ship will be in the old san juan area.. take a walk in the Princesa walk, visit the museums, go shopping, visit the Fortress, the oldest church in the Caribbean www.gotopuertorico.com|||If possible, you should go to El Yunque. It's a rainforest/national park. It's BEAUTIFUL!|||Where to start - science buffs will enjoy Aricebo - the giant radio telescope featured in the movie "Contact." Jajome Terrace is a great place in the mountains with gorgeous views. El Yunque is the rainforest (only one in the Caribbean!) and offers a visitor center and numerous hiking trails. There is also a bioluminescent bay that you can take boating tours on, scuba diving options, the Bacardi Factory, and Old San Juan. Old San Juan has two forts - El Morro and San Cristobal and that area has some of the oldest buildings in Puerto Rico - beautiful architecture. For beach activity, you might try kite surfing. That qualifies as exciting! Great this time of year. I've just scratched the surface, but those are some of my suggestions!
