1. Those looking for something unusual will not be disappointed upon visiting Key Largo. The rich opportunity for ecological exploration and quirky attractions make Key Largo unexpectedly fascinating. Those looking to get close to nature should consider taking a dolphin tour at one of several dolphin-only aquariums, charter a boat to see them in their natural habitat, or swim with a dolphin at Dolphins Plus. There are also quite a few companies in Key Largo that offer glass bottom boat rides, especially helpful for those too timid to snorkel but still want to explore the coral reefs that make Key Largo famous. Eco-tours through the Everglades National Park can offer sightings of the most diverse array of animals in the world, from bald eagles to deer to alligators. Adventurous types looking for a rush on the ocean can arrange a parasailing or kayaking lesson. Paddleboarding is up and coming, they have tours and classes in islamorada at Post Card Inn.  Those who always love a little pop culture should make a trip over to the African Queen at Mile Marker 100 to visit the ship that appeared in the classic film of the same name. Finally, for those who really desire something to write home about, visit the Key Largo Undersea Park at Mile Marker 103.5 for the world's only undersea hotel...that's right, you can enjoy room service while a sea turtle floats by your window.
