Segway itself was easy to learn. I had a moment of panic, but our tour guide gave me easy-to-follow instructions, and I was able to get control again.
The tour was fun, informative, and lovely. I am a local and learned history and saw tree carvings I didn't know and hadn't found yet.
I recommend the experience and the tour. We went in the morning, so, though it was hot, it wasn't unbearable.
