Excellent
Experience and information excellent. Guide, although not fluent English, was still completely capable of describing it all in English, tho at times we either helped him with the word, or weren't able to fully hear or understand him, but this element was marginal, but our group was 80% English!...loved the walk, loved the way tunnels was done, even though that part was not at all like we expected . Felt at times, rushed, during walk, esp. near oasis area.. didn't feel I had time to take photos
