Some of the best food I've ever had was in BelgradeI mean, everyone is welcome in Belgrade for cheap great dive courses
We have an awesome lake in the city, and a great deep lake with crystal clear water for any more advanced dives. Also, nice caves for the adventurer ones.
Save your money on cheap flights, food and courses.
The accomodation might cost up, since the influx of ukranian and russian refugees. But it's still cheaper than most of the Europe.
