Took the GBBTour April, 2024. Captain Luke was our guide. From his extensive knowledge of the Springs, I thought he'd been doing this for 20 years. He said it was actually only 2 months! Example subjects covered include: Why it's called "Silver" Springs, Gallons produced per day, TV show "Sea Hunt", Offensive Treaties, Spiral "Snow-storms", 2 boys who sank their GBBoat, Wild life, and James Bond-007. Much more and this was only the 30 minute tour. $15 Adults, $14 Seniors. (Plus $2 for the State Park) There's also a 90 minute tour we'll be heading back for. Hope we get Captain Luke. (Be sure to tip!)
