I live in Fort Lauderdale and have explored the Everglades a few times (hiking, biking, etc) over the past several years, so I thought I knew what to expect. This trip blew my expectations out of the water though, it's one of the coolest things I've done so far in Florida and am thrilled I brought my parents along when they were visiting. Don't write off the area as a swamp, it's absolutely beautiful.
Captain Willy was really knowledgeable and got us close to some beautiful wildlife. We did the 90 minute private tour and it was a nice mix of zooming along the water to see the various ecosystems and stopping the boat so he could explain what was going on around us (alligator nests, river full of lily flowers, native bird behavior, etc).
I will definitely be back to bring friends when they're in town.
