We took the Bavaro Runners excursion (not zip lining) with Jonathan (tour guide). He was awesome. Non stop humour, history and stories. The tour was well worth it. Sugar cane and cigar factory, horse back riding, traditional domican lunch, visit to Maria's house where she makes all her own cocoa, coffee, coconut oil, cocoa butter, etc., and finally Macao beach (not very nice actually). Would recommend. Good bang for the buck.
