About skiing on Ararat,  best time is beginning of april till middle of may.  We using winter camps for ski tours.  Because of snow,  base camp is 2900m,  second camp is  3500m. Also we try Ararat peak from 3500m,  because of weather conditions and snow.   Sometime we can use perters on mountain,  they are carrying less equipments, and less kg. Also you need bring your warm gear for bad weather conditions,  we care melting snow water for drinking, of course we buy  some water from dogubayazit town too.  If good weather conditions, Some skiers skiing from Ararat summit to down,  but some ski down from 4600m,  depend of weather on Ararat. Or course when we are on mountain,  we always follow weather snow forecast. wish see you on Ararat
