Home to over 10 festivals, Croatia is building a poweful reputation as the new summer party / holiday destination dubbed the new Ibiza. Learning a little bit of Croatian will get you a long way.
These are four of the best.

Garden Festival
Set in Tisno, apartments are meters away from the strip of beach that holds parties daily 12 mid day - 1am.
The party then continues to the open plan club Barbarellos. This is where the party goes on untill 6am. Here you will find experienced party animals of a mixed age. Laid back atmosphere, good vibes all round.
Highlights - Catz n Dogz, Cedric Mason, PBR Streetgang  

SONUS
I knew this was one i could not miss. Put together by Timewarp on Croatia's notorious Zrche beach in Pag, along a strip of pebble beach. 5 huge superclubs, hammocks over water, balcony beds, massive open plan out door design. These clubs set them selves in Europes top clubs. Artists included Riccardo Villalobas, Lucciano, Seth Troxter, Valentino Kanzyani. My highlight being Loco Dice, possibly the best DJ set of 2013!

DIMENSIONS
Huge variety in electronic genres, mixed European crowd, this year with a heavier UK presence. High light here was the Boddika & Blawan boat party.  This party can be described as "Psychedelic space tribe". 2013's best boat party! Police are out in force with ridiculous amounts of under-covers! This kind of put everyone on edge...

UNKNOWN

Predecessors of Hideout, creators of warehouse project and  Field day make a beautiful super-baby - UNKNOWN.
No one knew what it would be like and i think i speak for everyone when i say i was blown away. They have bagged the perfect venue, on-site luxury apartments, crazy live interactive art work, secret boiler room island, and lots of secret antics. This place, unlike alot of festivals has alot of spaces to chill day and night, you can go to the beach or chill in hammock park. This place has it all. Highlight of the festival would be the Forest stage & Mad Ferret Stage, reminiscent of an illegal party in the woods... but with laser cannons and smoke machines.
