We did the 2 day trip with Nikki as our guide. She got us up close and personal with kangaroos, wallabies, koala, echidnas, eagles, lizards, and too many birds to name. She was a wealth of knowledge on the animals, the island history, and fielded our numerous questions. She also cooked up a killer BBQ lunch. I would definitely recommend KI Hire a Guide to anyone looking to visit the island. While the 1 day trip is nice, having the second day let us not only see the island sights but also spend more time with the animals. It was also quite easy to leave the rental car on the mainland, ride the ferry over, and get dropped off back at the ferry late on the second day for the return ride.
