Of all the fun pop-up experiences happening in and around London right now, Vestal Voyages, the world’s first floating pop-up bar, might be the only one that gets me to don a life vest. The scene is a 50-ft classic canal boat, where a maximum ten guests at a time are invited to push out for a leisurely cocktail-fueled voyage along Regent’s Canal. Sailing from King’s Cross you’ll float through the longest tunnel on the canal network before finally emerging in fleafy Islington, downing luxurious libations all along the way. I couldn’t think of a better way to spend a lazy afternoon – weather permitting, natch. For more info tweet @vestalvoyages.
