Not only is Montreal one of North America's top destinations for gay nightlife, it also boasts arguably the most popular gay bathhouse scenes in the world, with no fewer than half-dozen men's saunas around town. Some of these are pretty low-keyed and cater primarily to locals, but there are a few notable venues in the city's vibrant Gay Village that draw a steady flow of regulars, including plenty of gay tourists in town for fun.
The most famous of these is Oasis Sauna (1390 rue Saint-Catherine E, 514-521-0785), which is open round the clock and pretty much promises its patrons a good time - if you show up here and find that there are fewer than 10 other guys patrons on the premises, the management will refund you the admission cost. Open 24/7 and on one of the busiest blocks in the entire Gay Village, you can rest assured that you'll nearly always find that many guys in here cruising around, and on some nights the place is absolutely crawling with men on the make, from hunky muscle dudes to older gents to collegiate twinks.
Sauna culture in Montreal tends to be more acceptable and mainstream than in other North American cities - more typical of what you'll find in Europe. So you really do tend to find all walks of life at Oasis and the city's other bathhouses. Oasis is a fairly friendly place with extensive facilities - a large shower area, lounge with pool table, steam room, hot tub, dry sauna, porn-viewing areas, and, of course, an extensive network of cabins and lockers. At 10,000 square feet, there are plenty of dark corners and glory-hole-studded corridors to wander about in.
Two other Gay Village bathhouses well worth checking out are GI Joe Sauna (1166 rue Saint-Catherine E, 514-528-3326), which is generally considered to be the preferred destination among guys into fetish, leather, and kink (there are rooms with slings); and Sauna Centre-Ville (1465 rue Saint-Catherine E, 514-524-3486), which is bigger with locals - it's less expensive, a bit older, and has fewer frills, but those who come here regularly find no shortage of thrills. GI Joe, on the other hand, is quite a well-done sauna, with two hot tubs, a popular rooftop sunning area, and multiple areas for group play.
If you find Oasis a bit too vanilla for your tastes, you might want to give GI Joe a try.
The city's other gay saunas are located a bit farther from the primary gay district, on the Plateau, and cater more to locals, which can be fun if you're seeking a more authentic experience. Keep in mind that the clientele and staff at these other spots may be less likely to speak English, but then again, you're probably not as a Sauna in search of stimulating conversation. Sauna St-Hubert (6527 rue Saint-Hubert, 514-277-0176), which is right by Beaubien metro station, is the most popular of these - it's a smaller but quite nicely kept facility, and the size can actually make it a bit easier to meet other guys.
There are rooms of different kinds (some with slings), and different theme nights appeal to particular tastes. As with all of the facilities on the Plateau, you can generally expect a somewhat older bunch of patrons than down in the Gay Village.
Another option on the Plateau is the historic Colonial Bath (3963 ave. Colonial, 514-285-0132), which claims to be the oldest bathhouse on the continent - it opened over a century ago in 1914. With a central location near Boulevard Saint-Laurent, a lovely rooftop terrace, and attractive steam, sauna, and shower facilities, it's definitely cultivated a loyal fan base over the years. However, outsiders may find it a little hard to fit in, as the clientele skews heavily toward long-time locals.
