Perhaps the best deals for flights can be found through Skyscanner and cheapoair.ca. For colleagues flying to Europe, it is often less expensive to have a flight to Sofia and then take a local flight to Varna or a bus directly to Albena (see below).

1. Sofia-Varna-Albena: You can take a flight, bus or train to Varna and then either (i) a bus to Albena or (ii) use the shuttle which we are trying hard to arrange (we hope it will be done).

Buses and trains for Varna can be taken from the Central Bus Station Sofia and the nearby Central Train Station in Sofia.

You can get to the Central Bus Station and the Central Train Station from Sofia Airport by bus 84 and by metro - Line 1 to metrostation Serdika and then taking Line 2 to the metro station at the Central Bus Station and the Central Train Station.

2. Sofia-Albena: In May there are only 4 buses a day leaving for Albena:

2.1. At 10:30 and 22:30 - Bus Company Union Ivkoni (as a final destination type Kavarna).

2.2. At 11:30 and 21:30 - Bus Company Grup / Etap (as a final destination type Kavarna). These two buses should be taken if for some reason you cannot use the buses of Union Ivkoni above; the reason is that the busses of this company use a bus stop that is ~ 1 km from the conference hotel.

The company Hippo Taxi offers to meet colleagues directly at the airport - the driver will hold a sign "Spacetime Conference". The taxi fare is 52 BGN (~26 EUR) + airport fee of 3.00 BGN (~1.50 EUR). If you prefer a taxi driver to wait for you, please email your flight information (number, arrival date and time) to office@hippotaxi.bg and explain that you are attending the Spacetime Conference and that they made the offer to meet attendees at the airport; also indicate whether you will be paying with a credit card or cash. [During the last two years, particularly during the last several months, the taxi fare went up; in 2019 it was 40 BGN.]

You can also take a Hippo Taxi for sightseeing - simply tell the driver that you are attending the Spacetime Conference.

To get an idea of how time is spent outside the conference room, here are some pictures of the free discussions at the Fourth Spacetime Conference held in the resort Golden Sands (~15 km south of Albena) in June 2016.
