We’ve used Shaka Guide for Hawaii tours (2021/2022) and this week in North Dakota (Theodore Roosevelt National Park) and South Dakota (Mount Rushmore & Black Hills Tour, and Badlands National Park Tour) and in next week in Wyoming and Idaho (Yellowstone and Grand Tetons.) In my opinion, the experience with the Shaka Guides has been outstanding. The commentary, background music, the choices and recommendations - all have led to a memorable trip so far. I intend to continue to purchase these GPS tours on future trips. The Shaka Guides are an easy way to learn about the area without having to do a lot of up-front planning. They’ve done it all for you!! Thank you, Shaka Guides!
