How to get from Varna Airport to Varna and the Golden Sands

Public transport - take Bus 409 (at 15-minute interval) from Terminal 2 of the airport; it goes to Varna and continues to the Golden Sands. The travel time to the centre of Varna (the Cathedral) is 20 minutes and to the Golden Sands - about 50 minutes. A ticket can be purchased from the bus driver - its price is 3.00 BGN (Bulgarian lev; plural - leva). When you enter the bus tell the driver that you are going to the Golden Sands and ask at which bus stop to get off.

Taxi - the cost to the Golden Sands is 25 Euro (~50 leva); for a group of 4 or more see Varna Airport Taxis

More information on how to get to hotel Lilia from Varna airport by bus 409:

Bus 409 travels from the airport to Golden Sands (at 15 minutes) - the last stop is the "centre" of Golden Sands in the Riviera complex.

As hotel Lilia is about 20-30 minute slow walk from the last stop of bus 409, the hotel kindly agreed to arrange for the taxi driver working for the hotel to wait for the arriving by bus colleagues; you will have a discount - 8 leva (instead of 10), which is about 4 Euro.

All who intend to take bus 409, please send the following information to

Airlines + flight number
Time of arrival at Varna airport

This will allow the hotel administration to estimate when to send the taxi to the last bus stop. The taxi driver will be holding a sign with your name.

All colleagues attending the conference will have a discount (5 %) at supermarket Valdi (open 24 hours) - just tell the cashier that you are attending the conference organized by the Minkowski Institute at hotel Lilia. Valdi is one minute walk from the hotel - just turn left immediately after you exit Lilia from the entrance toward the sea.

The roof (9th floor) of Hotel Lilia, where the Welcome reception will be held on May 29, 2016. Update: As we ordered a variety of hot meals (that cannot be brought to the roof) the Welcome reception will start at 19:30 at the terrace of the main restaurant of hotel Lilia. We will discuss with the colleagues attending the conference whether the Goodbye reception (without hot meals) can be held on the roof.
