La Isla has quietly become the reliable choice among Quito's saunas, and the reviews keep saying the same two things: it's clean, and the bar staff are genuinely friendly. The setup covers what you want — dry sauna, steam room, private cabins, a cinema room, a smoking area and a bar — plus massage and treatments if you're in the mood to actually relax. The house rhythm is built on a simple alternating calendar that covers all six opening days: naked days on Tuesday, Thursday and Saturday, underwear days on Wednesday, Friday and Sunday. Parties lean clothing-free. Doors open at two in the afternoon every day except Monday, closing at eight on weeknights and nine from Friday to Sunday. You'll find it at Avenida Atahualpa and Rumipamba, near the Estadio Atahualpa in the business district north of the centre — an easy, safe part of town to reach. Two practical notes from people who go often: bring small bills and coins, because the bar insists on exact change, and ignore any old rumor that the place closed — that dates from 2021 and is long out of date. Their Instagram is the live channel for schedules and party announcements, and it's the one to trust over any website you might find.
