What a great tour, and adventure. Guide was great. Cave of the Winds was once in a lifetime experience, as was Maid of the Mist. The park trolley was a fun ride around Goat Island, and over to the side of the park where Maid of the Mist docks. This tour is highly recommended.
Note that the tour guide is only with you for a tour of the falls sections of Goat Island. The Caves of the Wind and Maid of the Mist tours are self guided. Which is great, as you can travel at your own pace for these two tours,
