"Really beautiful lake and with the time of the day can see different shades of blue from the lake. Have different view points surrounding the lake every one should visit."

"In August, the lake is a calm, grey-blue, a quiet beauty often overlooked by those expecting its famous bright blue. I saw a stranger offer to take a photo for a disappointed couple, saying: "The light still loves you."
It was a gentle reminder that the best of humanity shows up not when things are perfect, but when they’re imperfect. The grey-blue lake became a mirror for kindness, reflecting how we care for one another, not just the view."
