Party inside a glacier and lava tunnel at Secret Solstice Festival

Secret Solstice festival is welcoming back signature events Into The glacier and The Lava Tunnel following the success this year.

Ticket holders for these events can expect performances in Europe’s second largest glacier or inside a 5,000-year-old lava tunnel.

The festival will return to Reykjavik in Iceland on June 21 and 24 for 96 hours of straight daylight.

This year the breathtaking Icelandic setting hosted Kerri Chandler, Dubfire, Jamie Jones, The Black Madonna and more.
