Beer Spa’s in Prague

Well they are popular enough that a new one opened in Revolucni Street this year. I'm not sure this would be considered a summer activity. Much more likely if it's cool in the city that a couple might elect for a hot herbal bath for 30 minutes but you'll have to go some to get your monies worth of "unlimited" beer in 30 minutes. Then there's a "warm-down" of another 30 minutes and you can stop there if you want. They usually offer a massage during the booking process so that takes another 30 minutes hence why they often describe it as 1-1.5 hours. I've only ever seen couples do this as a kind of late afternoon relaxing activity before going out somewhere for dinner but they always recommend not taking a shower after the bath for a few hours to allow the herbs a chance to do their work.
