Starting in Poland on September 30, the two bands will travel mainland Europe and the UK until the final date in France on October 16.
"Salute dear friends and foes!" says Enslaved vocalist Grutle. "We are happy to announce some more tour dates for you – we are going to share stage with legends in High On Fire! I can guarantee you that this will be a tour for the books, so get ready for some excessive indulgence in heavy music madness!"
"Cometh the conquerors, to break all beliefs!" adds High On Fire frontman Matt Pike.
Tickets go on sale Thursday June 21 at 9am.
High On Fire are currently celebrating their 20th anniversary and headlined Desertfest in London last month. Enslaved released their fourteenth album E last year.
