Regions of Bulgaria and how to combine them

Geographers describe Bulgaria as four bands of high and low ground running east to west. From north to south they are the Danubian Plain, the Balkan Mountains, a transitional belt of lower ranges and basins, and the Rila–Rhodope region. The land rises from the Black Sea towards the west, so the western end of the country is almost entirely high ground. Sofia, in a high basin, sits in that western part.

That shape is worth keeping in mind when you plan. The Balkan Mountains run from the Serbian border to the sea at Cape Emine, so every trip between north and south has to cross them. A route that follows one band at a time, such as Sofia to Plovdiv and on towards Burgas, or Sofia to Veliko Tarnovo and on to Varna, avoids zigzagging over the range and saves time.

Climate follows the bands too. Most of the country has a humid continental climate, with alpine conditions in the highest mountains and a Mediterranean influence in the far south. On the Danubian Plain the mean temperature is about −1 °C in January and 24 °C in July.

Plovdiv is the second-largest city, 144 km south-east of Sofia on the Maritsa river. It was European Capital of Culture in 2019 and is often described as the oldest continually inhabited city in Europe. The line between Sofia and Plovdiv was the first in Bulgaria to be electrified, in 1963, and remains the backbone of rail travel east from the capital.

South of Plovdiv, the Rhodopes stretch about 240 km towards the Greek border. They are the largest Bulgarian range by area and lower than Rila or Pirin, with Golyam Perelik at 2,191 m. Pamporovo, the Rhodope ski resort, is about 85 km south of Plovdiv. The range is known for karst gorges such as Trigrad and for spa towns with mineral springs, including Velingrad and Devin.

North of Plovdiv, between the Balkan Mountains and the Sredna Gora, lies the Rose Valley around Kazanlak and Karlovo. The rose-picking season runs in May and June; the bloom historically started between 10 and 20 June, but in 2024 it began nearly a month earlier.

The coast runs 378 km from the Romanian border to Turkey and has two main gulfs, at Varna and at Burgas, each with a major port. Varna, the third-largest city in the country, anchors the north. Burgas anchors the south, with Nesebar on its peninsula to the north and Sozopol 35 km to the south. Both old towns began as Greek colonies, and Nesebar is a UNESCO World Heritage site.

The coast is a summer region. Sozopol's busiest months are May to September, and Sunny Beach, the largest resort, lies just north of Nesebar. The coast guide covers each town and when to avoid it.

Trains run by BDZ link Sofia with Plovdiv, Burgas and Varna, including night trains to the coast that are popular in summer. Fares are dynamic and depend on the day and time. Buses fill gaps the railway misses; Bansko, for example, has bus connections to Sofia and Plovdiv as well as its narrow-gauge railway. A car gives the most freedom in the mountains but needs an e-vignette, and the UK Foreign Office warns about road conditions and night driving.
