So we made it to Varna after our mammoth train journey. It wasn't anything like we expected. The sleeper compartment was comfortable, though a little dated and old, but the carriage seemed to just get hitched to different trains along the way. That meant we were confined to the one carriage for the whole 35 hours. Very lucky we took lots of food as there was no dining car!
We awoke on the train yesterday morning to a completely different view from Central Europe. It could have been Jamaica: hot, with green hills covered in trees. Beautiful!
We spent yesterday and today on the beach, chilling out and swimming. The Black Sea here is a bit grotty, with rubbish and stuff, but nice anyway. We're hoping to go on a day trip to some cleaner beaches, maybe even do some kite- or wind-surfing as well as snorkling. Should be fun.
