This was the highlight of our trip. John and Allison are very friendly, helpful and knowledgeable about the park. The bikes were very easy to operate and are fun to ride. My wife and I are casual bike riders and this tour was perfect for us. The really refreshing thing I will highlight is that there is absolutely no upsell on this tour. The price you pay is for everything - park admission, water, snack, and even a hotel pickup.
My advice is to take this tour early in your trip. John and Allison have lots of great information on the park, which will enable you to make the most of your outdoor time in the park.
Thanks for the great time.
