Emerald Lake in Yoho National Park, near Golden, Canada, is a stunning alpine lake known for its vibrant turquoise waters, a result of glacial silt. It's accessible via a short, well-maintained road, and offers ample parking. Visiting solo is easy thanks to well-marked trails, though guided tours are available for more in-depth natural history insights. The best time to visit is late June to September when the lake is fully thawed, but winter visits offer beautiful snowy landscapes. Kayak rentals and hiking around the lake provide engaging activities. Plan for 2-4 hours to fully enjoy the area. Parking is free, but park entry fees apply, typically around CAD 10 per adult per day. Make sure to pack layers, as mountain weather can be unpredictable.
