Bulgarian Black Sea Coast at $452 RT

Picture this: You wake up early so you can drive out to these cliffside caves and watch the sun rise over the sparkling water of the Black Sea. This might be the most spectacular view on the whole coast, you think to yourself, knowing full well you'll see one just as gorgeous tomorrow. And again the next day.

On your way back to Burgas, you decide to skip the ancient seaside port of Varna (you'll catch the Sea Garden there on another day) and stop by the eerie Stone Desert instead. After all, towering natural formations like these can only be found in two places on Earth: the western coast of Australia, and right here.

Finally, you'll end your day with a visit to the Monastery of Saints Constantine and Helena outside Varna. Bulgaria has plenty of monasteries, including one carved into the sea cliffs just a few miles away, but this spot has an especially romantic draw: holy remains of St. Valentine himself.

Sounds like a great trip, right? There's just one catch: You'll have to book quickly, because there are only a few dates available at this price. But what's life without a little spontaneity? :-)
