Rila

Musala is 2,925 metres, and that number settles an argument: it is the highest point not merely in Bulgaria but on the whole Balkan Peninsula, eight metres above Mount Olympus and some sixty above Vihren in Pirin. The name is generally read as a Turkish rendering of the Arabic for "close to God". It stands near the eastern end of a granite massif that also functions as the country's water tower — the Iskar, the Maritsa and the Mesta all rise inside the park, which is to say that the Danube, the Aegean at Enez and the Aegean at Keramoti are all fed from the same set of cirques.

Национален парк "Рила" was declared on 24 February 1992, and its subsequent history is mostly a story of getting smaller. It was recategorised and renamed by Заповед № 397 of 15 October 1999. Then, on 26 June 2000, 27,370.7 hectares in the west were excised and declared Природен парк "Рилски манастир" — a restitution, returning the forest to the Rila Monastery, which had held it before 1947. That excision is why the park is not one shape: what remains is a large massif plus a detached western block, with the monastery's wedge between them. The monastery itself, founded in the tenth century around the hermitage of Ivan Rilski and a World Heritage site in its own right, therefore lies outside the national park, as does the Borovets ski resort on the northeastern flank. The register now records 77,956.44 hectares, restated in July 2024 after a geodetic survey found the park about 3,064 hectares smaller than the old forestry maps had it — no boundary moved, only the measurement.

The glacial record is the reason most people come. Around 120 lakes lie within the park, and the best-known are the Seven Rila Lakes, a staircase of cirque tarns strung down a single valley and named for their shapes — the Tear, the Eye, the Kidney, the Twin, the Trefoil, the Fish Lake and the Lower Lake. The Eye is the deepest cirque lake in the country at 37.5 metres. Smradlivo ezero, over in the Rila valley, is at 0.212 square kilometres the largest glacial lake on the Balkan Peninsula, which gives a sense of the scale involved: the biggest tarn in the range is about nine hundred metres long. Four strict reserves sit inside the park, and one of them dominates — the Central Rila Reserve, at 12,417 hectares, is the largest strict reserve in Bulgaria and on the peninsula. Parangalitsa, protecting old-growth Norway spruce, dates from December 1933 and is among the oldest reserves in Europe. Brown bear, wolf and Balkan chamois hold on here, and the Rila primrose, Primula deorum, grows in these wet alpine turfs and nowhere else on Earth.

What's worth knowing before you go

There are two quite different ways in. For Musala, take the gondola from Borovets up to Yastrebets and walk from there past the Musala huts — a long but untechnical day that puts you on the summit in the company of a meteorological observatory. For the Seven Lakes, the approach is from Sapareva Banya to Panichishte and then the chairlift to the Rilski Ezera hut, from which the whole cascade is a half-day loop. Samokov and Govedartsi serve the north, Yakoruda and Belitsa the south.

The season is short and the weather is genuinely mountain weather: July to September for the high ground, with afternoon storms common enough that summit attempts start early. September gives the same terrain with thinner crowds and better light. Note that the Seven Lakes are among the busiest places in Bulgaria on a summer weekend, and that the chairlift concentrates everyone into the same two hours — going up on a weekday, or walking from Panichishte instead of riding, changes the experience entirely. One detail worth carrying: the boundary you cross when you drive from the monastery up towards the ridge is a property line from 1947 before it is anything else. The park's shape is a restitution case, and the two halves of Rila are administered by different bodies because of a question about who owned a forest.
