Ontario's secret 'Blue Lagoon' swimming hole has cascading waterfalls and crystal-clear water
If you're looking for the ultimate summer cool-down spot, this hidden natural swimming hole in Ontario is a must-visit.
Tucked away in Northeastern Ontario, just a five-hour road trip from Toronto, this bucket list-worthy swimming hole with a waterfall is perfect for a refreshing dip. This secluded spot is way off the beaten path and not for the faint of heart, making it a true adventure for those who seek it.
Located just outside of Sudbury, the waters of the swimming basin come from the Chiniguchi River.
The river, which is near Wanapitei Provincial Park, runs through the Wolf Lake Forest Reserve and down several cataracts into Paradise Lagoon, which is also known as the "Blue Lagoon" to locals.
The lagoon offers a dreamy spot to swim, as well as the perfect place for some gorgeous photo ops.
The beautiful lagoon is surrounded by steep rock walls of granite and quartz. While it can appear darker, the lagoon's waters have often been described as having a turquoise or "Windex"-like colour by those who venture to the swimming hole.
Because of its secluded and almost hidden location, Paradise Lagoon is likely to have fewer crowds than other popular swimming holes in Ontario.
You can get here by canoe or hike. The terrain can be a bit rugged and isn't well-marked. The road is not maintained, so use caution if you are accessing the lagoon by hike and car. However, a handy guide for visiting put together by Backroads Bill Steer, a professor at Canadore College and Nipissing University, lays out exact details for reaching the swimming spot, including a handy video showing you how to reach the lagoon by hike.
If you plan on visiting the lagoon, be sure to respect the environment by picking up after yourself and leaving no trace of your visit.
Get ready to take in the stunning beauty of this hidden natural lagoon this summer.
