Sunglasses - Whether you're living the Bulgaria beach life or getting stuck into après-ski in Pamporovo, a good pair of shades will see you right.
A camera - With sights like the Alexander Nevsky Cathedral, the Rila Monastery and Plovdiv Old Town on display, you can bank on taking a lot of pictures!
A translator app - Bulgaria uses the Cyrillic alphabet, so road signs and restaurant menus will be indecipherable. Time to send your trusty smartphone to the rescue!
Painkillers & hydration treatments - From the Sunny Beach clubs to the Sofia nightlife, there are endless opportunities for good times in Bulgaria. Make sure you're equipped for a sore head or two.
An adapter plug and voltage transformer - Bulgaria uses the standard European 2-pin plug. The voltage here is 230V, so you'll need a step-down transformer if you want to use appliances that require 110V.
