Approach from Poland:
I'll skip the description of getting there, because it is almost the same as already written in case of Rila mountains.http://www.centralnaavtogara.bg . Information for tourists traveling by car - Bulgarian main roads are rather good quality. Local roads - not necessairly... We took a shortcut to Melnik and we came across a road rather for donkeys but not for cars (You can see it in the picture).
This is the town with a population of 10 thousand residents, which is an important tourist centre in Bulgaria. It is divided into two parts: old Bansko with plenty of turists and town residents and tourist complex, which clearly shows overinvestment. Many of the buildings are empty, and they are for sale.
Due to the large number of hotels, finding accommodation is not a problem. However, You have to take into consideration, that hotels 3-4-stars are quite expensive. It is better to look for two-star hostel.
The old part of Bansko is a charming place for the romantic walks. You'll find here a number of pubs offering Bulgarian cuisine. What is more, the prices are relatively low, for example, beer on the main street costs less than 1 Eur (1,40 lewa), and you can eat a good lunch for about 4 Eur (7 lewa). A characteristic view on the streets are an elderly women sitting on a benches on the street in front of their houses. The town also offers cultural entertainment: Museum of Icons, Museum of Neofit Rilski, Museum of Nikola Wapcarow (Communist poet, with a relatively poor work, one collection of poems called "Motorni Pesni" was issued, but in 1952 He was posthumously awarded the International Prize of Peace ... of course, in Moscow).
Melnik is a unique town, situated near the slops of Pirin, surrounded by sandstone rocks. There is less than 300 permanent inhabitants.
Currently, Melnik is a charming tourist town.
There are also professional wine bars, which offer wine for tasting and buying (also vintage wine).
