Late May to early July, and September, are the best all-round months: warm, green, and without August's crowds and heat.
The beach season runs roughly from mid-June to mid-September; the sea is warmest in August and still swimmable in late September. July and August fill the coast and double the prices.
The high mountains hold snow into June — the Seven Rila Lakes and the peaks above 2,500 metres are a summer walk from about July. Autumn in the Rhodopes, late September into October, is the quietest beautiful thing in the country.
Ski season runs from about mid-December to late March in Bansko, Borovets and Pamporovo.
The Rose Festival in Kazanlak is the first weekend of June, and the harvest itself happens at dawn through late May and June.
