Description
A river valley high in the Pirin (Пирин) Mountains between Vihren (2914 m) and Todorin Vrah (2746 m), this site holds an excellent range of alpine and subalpine birds. Above the 2,300-2,400 m tree line, the grassy slopes have orol skalný, čavka žltozobá, krkavec čierny, vrchárka červenkavá, ľabtuška vrchovská, uškárik vrchovský (the Balkan subspecies balcanica with extensive black on the throat, a likely future species split), drozd kolohrivec (alpine subspecies alpestris), strnádka cia and if you are lucky, murárik červenokrídly.
The mixed conifer forests are important for orešnica perlavá (look for them collecting seed from Macedonian Pine [Pinus peuce] cones), krivonos smrekový (on my visit, two different forms, one small-billed, feeding on Norway Spruce [Picea abies] cones, the other large-billed and closely resembling krivonos sosnový, feeding on Balkan endemic Bosnian Pine [Pinus heldreichii] cones), sýkorka čiernohlavá (the alpine subspecies montanus), žlna sivá, tesár čierny, králik zlatohlavý, králik ohnivohlavý, kôrovník dlhoprstý and sýkorka chochlatá. The alpine chalets hold breeding dážďovník plavý and lastovička skalná, both of which feed widely over the valley, and žľtochvost domový.
Lower down, the mixed woodland around Bansko holds ďateľ prostredný (which can even be seen in parks and gardens in Bansko) and kôrovník krátkoprstý. Also look for passage migrants like sedmihlások hájový and kolibiarik sykavý. Open areas have vrana popolavá, kanárik poľný, and strnádka svrčivá as well as strnádka obyčajná. Overhead, lastovička červenochrbtá feed together with more familiar belorítka obyčajná and lastovička obyčajná. The river holds vodnár potočný and trasochvost horský along its full length.

Access
The mountain resort of Bansko (Банско) has an excellent range of accomodation and can be reached easily by train or bus from the capital Sofia. From Bansko, the best option is to hire a taxi to either the Banderitsa Chalet (Хижа Бъндерица, 14 km) or Vihren Chalet (Хижа Вихрен, 16 km), where you can also stay to explore the area, or walk along the many footpaths back to Bansko.

My visit was in autumn, after most summer visitors had left. If there are other good species to be seen here in spring or summer, please leave a note below and I will add the details!
As well as the many birds, the site holds occasional Brown Bear and Wolf. It is botanically very rich, including the famous 'Байкушевата мура' ('Baikushev's pine'), an ancient Черна мура / Bosnian Pine (Pinus heldreichii) estimated to be over 1,300 years old, one of the oldest trees in the whole of Europe.
Thanks to Stivi Musievski for tips on additional birds that can be found here.
