The Bus to Bourgas has been re-enstated times to follow .....

good news while you are at it Martin can you put in the times for the Karnobat bus aswell

BOURGAS BUS TIMES
The bus to Bourgas is between 9.10 am and 9.30am, the time varies so get there early.
It's destination is The Bus Station behind big Bila, and is a good half hour walk to the Sea Gardens so not for the faint hearted. If you get off as the bus turns right at the lights before Bila it's slightly closer.
SINGLE FARE 5.60 LEV (have the right money as I was overcharged once) !
As far as I know there is only 1 bus back and leaves at 4.00pm but please note it's a coach in a morning, but a small Blue mini-bus at night.
The journey time is approx 1 hour 15 minutes.

KARNOBAT BUS
Goes to the Bus Station at the bottom of Town, but you can get off 1 or 2 stops earlier in Town, but I would suggest always getting the bus back from the Bus Station as the route back out of Town can vary !
Full details to follow.
Outward 7.20am from Cherkovo (but can vary by 10-15 mins so get there early say by 7.10am).
Last Bus Back 4pm from Karnobat
Journey time is about half an hour, the same as by car as it goes via Antimovo and Dragantzi. Though if there are kids going to Sernavo to school, it goes there first, and turns right, before returning across the top of the village (but does'nt come back into the square) 10 minutes later.

Thanks Martin most helpful
