We had an 'aggressive' 7-day tour with Nestor that included climbing Volcan Pacaya and Tajumulco, and seeing Antigua, Lake Atitlan, Semuc Champey the ruins in Tikal and Flores. Nestor and his driver Rodrigo were incredibly flexible to changes in our schedule and long drives (10-12 hr drives!), clearly experienced in traveling the country, and also fun guys to hang out with. It is clear Nestor enjoys guiding and passing on his knowledge of the various sites. Would definitely go with him again!
TOUR GUIDE RESPONSE: Thank you very much Dilan! Cheers!
