As described by Tourism Alberta:

You have seen photos of the lake but they haven’t prepared you for how it feels to experience it yourself. Rounding the corner, the sight of the emerald green water and rugged peaks and glaciers hits you viscerally. You’ve never seen anything so dramatically beautiful. Late in the day, with the glowing sun dropping behind Mount Victoria, it is quiet and still. As you wander around the lakeside path it seems like the whole scene is for just you to enjoy. It is a feeling you will remember forever.

This is where we got engaged, it's a stunning place in BC, just a few hours drive from Calgary.

Again, another quick intro to Emerald Lake:

Emerald Lake is one of the most admired destinations in Yoho National Park, with an unmatched diversity of both activities and landscapes suited to the enthusiastic traveler. It was discovered in 1882, when famed mountain guide Tom Wilson was led lakeside while rounding up a group of horses that had gone astray, and was immediately taken by the vivid Emerald-coloured waters.

From the Banff Tourism board:

Summer in Banff and Lake Louise is all about sunshine, mountain adventures, and moments full of vibrant beauty. It is a chance to take a break from your daily routine and find fun and rejuvenation. Try something you never have before, like rock climbing or horseback riding. Be wowed by the spectacular beauty of Banff National Park’s mountains, lakes, and valleys on a scenic drive or helicopter flight. Unwind beside a campfire under the starry sky. It is time to connect with nature and truly relax.

Canmore is an authentic mountain community, where people from all walks of life live; including an impressive list of accomplished mountaineers, and Olympic athletes. Here, you can take in the one-of-a-kind boutiques, eclectic art galleries or just enjoy the atmosphere without crowds of tourists huddled on jam-packed streets. In fact, in Canmore, laid back is a way of life. Even the rock climbers here like to put up their feet at a local pub after a thrill-packed day on a vertical cliff. That’s the beauty of Canmore!
