The name says it all, The Underground, this is a small underground club in San Rafael. You may well have never heard of this club because, unlike most clubs in Ibiza, The Underground does almost nothing in the way of promotion. This is perhaps one of Ibiza’s best-kept secret club. The lineups are also never announced. The club is therefore a lot more intimate than the island’s big clubs. The Underground is divided into an indoor section with a DJ booth, dance floor and bar, and they also have a large outdoor terrace.
