Lake Crescent in Olympic National Park is renowned for its stunning blue water, exceptional clarity, and breathtaking surroundings. This glacially-carved lake, nestled in the northern foothills of the Olympic Mountains, offers visitors a unique experience with its deep sapphire to turquoise hues. The lake’s remarkable clarity is due to its lack of nitrogen, which inhibits algae growth, resulting in crystal-clear waters that can reach depths of up to 624 feet. Surrounded by lush forests and towering peaks, Lake Crescent is a testament to the raw beauty of the Pacific Northwest.
