There are three main bars on the island; Polo's Bar, Iguana Rock, and Voqui Bar. Generally people start at Polo's directly up the street from Calypso and then head to Iguana Rock to dance up the street from Polo's, hang a left when you hit the market. When Iguana's closes, head to Voqui for some late night pool located in the back room of Calypso or the sole Discoteca of the island, above Calypo's.
Instead of a discoteca above Calypso, there are now two discotecas in Puerto Baquerizo Moreno: La Isla the island and Neptune. Both are located on the main road and will sometimes charge a $1-3 entrance fee on the occasional Saturday.
