Lake Ontario straddles the border between Canada and the United States, and is one of the most famous lakes in the entire world. It has always been a popular destination among campers, thanks to the abundance of outdoor activities to be enjoyed on the shores of the lake. Yet, if you venture into the surrounding countryside, you can find sprawling mountain land which stretches into the Adirondack Mountains. This makes it the perfect location for a serene mountain retreat, and you can make the most of your time away by staying in a secluded mountain rental in the heart of nature. Head out to High Peaks Wilderness, where you can navigate your way through forests, and where you can see mountain views from all around.
