The guide Paul accompanied us on this tour and was never at a loss for a little joke, which made for a pleasant atmosphere. In addition, explanations were given again and again, it was at a comfortable level and you weren't exposed to noise all day long. Nature speaks for itself. Beautiful coasts. In my opinion it is worth taking the 10 hour tour as it gives you more time for the activities and you can see more coasts. In between there are always small breaks in which you can move freely. I can recommend it with a clear conscience!
