Porto
Ah, Porto! Source of eternal Harry Potterness, birth place of port wine, cod cake and sweet pastry heaven and most importantly - home of the world’s most steeply renowned instant butt lift hills. I dare you to do your steps in Porto and end up with anything but strong legs. Your steps are just that - steps. Uphill, often staircased steps. Not the small building adorning kind of steps - big, tall, you-have-to-make-an-effort-to-climb-them steps. And if as a wandering tourist you ever doubt which way to go, don’t worry. It’s always up. OK, maybe you go down once but then you always have to come back up. Highly underrated gluteal advantages aside, Porto is a lovely destination to touch up on Mediterranean charm and Portuguese glory. It's a place where a few days are not enough because little architectural and culinary gems are around every corner. Leave the stair-master at home and book yourself a longer trip - your glutes will thank you!
