Only recently have major airlines begun offering regular flights to Bulgaria. The discount airline Wizz Air flies direct from London and several other major European cities to Sofia, as do Bulgaria Air and EasyJet. There are a large number of international train routes to Sofia and Varna, departing from most major eastern European cities. There are a number of bus routes to Bulgaria as well, which tend to run more often than the trains. Expect an extra border fee when traveling by bus.

There’s a bit of bureaucracy involved in going to Bulgaria by car. Your car will be registered with a temporary “visa tag”, and you’ll be asked to pay a road tax of around 5 euros depending on which border crossing you plan on exiting out of. On the other hand, this means that there are no toll roads in Bulgaria. There’s also a charge of 4 euros to “disinfect” your vehicle when entering the country. In most cases, it may be simpler to take public transportation to Bulgaria and hire a car for a reasonable price inside the country.
