Honestly, discovering fun new places to go to in the summer is kind of my jam, guys. I just feel like there are tons of things to discover and to explore; and sometimes, you find something absolutely impressive, incredibly close to Montreal.
Like the Wallingford-Back Mine, a grotto located in Mulgrave-et-Derry, Quebec. This enchanting spot is roughly a 2.5 hour drive away from Montreal - which is the perfect length for an awesome summer roadtrip, BTW.
TBH, this looks like something out of some sort of fantasy novel. The grotto isn't only incredibly gorgeous, though: it's got water deep enough for you to swim (or kayak) in, making it one seriously fun summer destination. You can also go scuba diving, hiking, rock-climbing, and zip-lining in the grotto - providing you've got your own equipment.
Oh, and if you're not down to come pay this spot a visit during the summer, then no worries. Quebec's Wallingford-Back Mine is just as beautiful - and fun - during the winter, perfect for activities like ice-skating.
But, before planning to go to the grotto, make sure to check out this link for more information.
