We Re staying in key largo thru June 15 2013. We went on a real tourist air boat ride at an alligator farm which was fun but this time I really want to see the man groves, gators and or crocs...maybe even a manatee. Is such a tour even possible? We have a group of 9 people....one of them who is 4 but adventurous ..heck he snorkels an hour off a catamaran this morning...and two 12 year old boys. Just trying to see the best and most we can while down here! Even heard of a night time paddle board trip? Any suggestions ? Would love feedback ASAP....we are here now and don't want to miss out! Thanks!
