1. Swim with the Manatees, Nature Coast

Crystal River, a winter playground to the West Indian manatee, attracts between 400 and 500 of these gentle giant sea cows when water temperatures in the Gulf of Mexico begin to drop. Manatees like to frolic in the warmer waters of the spring systems around Kings Bay and are often spotted in the Three Sisters Springs at the Crystal River National Wildlife Refuge. Though no longer on the endangered list, they remain a “threatened” species. Local outfitter River Ventures takes guests to swim and snorkel with the manatees. Manatee season is from November to April, but they can be spotted around Crystal River year-round. Tours leave from 498 SE Kings Bay Drive, Crystal River, Florida. 1-877-581-8401. riverventures.com

3. Experience bioluminescence in a kayak, Indian River Lagoon

In the darkness of the night, kayaks glide across the Indian River Lagoon and Mosquito Lagoon in Merritt Island National Wildlife Refuge. Every swish of the paddle and movement in the water spawns swirls of glowing electric green color through the water. This glow-in-the-dark phenomenon, caused by a combination of single-celled microorganisms called dinoflagellates, warm temperatures and water salinity levels, occurs from June through early October. Come November through May, bioluminescent jelly combs, a creature similar to a jellyfish but without the sting, congregate in the waters of the Indian River Lagoon to illuminate the cooler nights.

The tour launch point is at Haulover Canal, Merritt Island National Wildlife Refuge, Titusville, Florida. 1-321-268-2655. adayawaykayaktours.com
