too early to say. last year was great conditions at the end of March as there was a big dump the last week of March. usually it is getting slushy and patchy on the bottom slopes but ok up top. This season has been a really weird one with several warm spells that have damaged the snow cover so who knows. Best to book late I would say
Was in Bansko 3 years ago over St. Patrick's day 17th March, conditions were terrible, pure ice. A week later i checked on webcam and lo and behold they had a huge dump of snow. Very much a case of you pays your money and takes your chances. Last year went out in February, conditions fab. Going out on 6th March and hoping it will snow VERY HEAVILY this week!!!
last year in borovets the march early april conditions were fantastic but the resort was empty.. also heard plenty of stories about people skiing 2 weeks after the lifts closed..
march has a very high precipation levels all depends on the temps if its snow or not.. because of last year i booked for march,, only paid £43 for my flight
