Croatia has joined Turkey and Bulgaria as one of the cheapest destinations for Brits in search of bargain holidays, new figures have revealed.

The Post Office Holiday Costs Barometer has shown that the Croatian Kuna is one of the fastest-growing currencies in terms of popularity this year.

Sarah Munro, Post Office's head of travel services, said that it was "inevitable" that holidaymakers would consider flying to destinations outside of the eurozone because of the strength of the euro.

"Croatia has been growing in popularity for some time now and in the early part of 2009 it is one of our fastest growing currencies - up eight per cent on the same period last year," she commented.

Munro added that holidaymakers are considering the cost of the different elements of their trip separately, such as flights, accommodation and the local cost of living.

The Post Office survey revealed Bulgaria's Sunny Beach resort as the cheapest holiday destination.

At £42 for ten holiday items, it was two-and-a-half times cheaper than Antigua, which was unveiled as the most expensive holiday destination. 

The survey revealed that ten holiday items in Croatia would cost £64.76 including a three course evening meal for two (with bottle of house wine) at £42.12.

France is currently the most expensive country in the eurozone, while local prices have fallen in both Greece and Italy.
