Excellent
Our guide was very informative, pulling over to the side of the road on occasion to point things out. We made a couple of stops where he gave us 20 minutes or so to ourselves to explore which we really appreciated. On arrival at Nuns Valley we had around 40 minutes to ourselves; our guide recommended a place to eat, a bar to try and suggested local specialities to try. On our return he offered to drop us back in town or at our hotel, whichever we preferred. We really enjoyed the experience.
