Mars Island 2021

Mars Island is a three night, all-inclusive festival experience on a private island in Croatia. Relax and restore with yoga amongst the trees, take a dip in the Adriatic Sea, watch a midnight screening or go gaze at the stars, and catch two intimate performances by Thirty Seconds To Mars. Mars Island is an experience like no other.

All passes include accommodation, meals, snacks, performances, and activities with the band.


The coastal waters of Šibenik, Croatia contain an archipelago of 249 islands stretching out into the crystal clear waters of the Adriatic. Nestled in this constellation of islands you will find Mars Island, one of only a handful of populated islands in the area. Mars Island provides a breathtaking backdrop for a perfect vacation getaway.
