I'm sure there are some people that add in color to their pictures, but they just look over saturated, and it isn't really needed, because in reality, it really is that amazing looking. The color can take on hues of Jade and turquoise and changes with the sky, whether it be cloudy or sunny. My own picture actually looked less colorful than what I was seeing in real time. I actually had to add color in, to match what I was seeing lol

you are asking what to whom???

The boat is a "ride," half day or whole - with interpretive guides. We camped in the state campground.

It was scheduled to reopen this morning, but you need to check on the WSDOT website for opening/closure. The website is up to date and shows webcams, too. Usually it is closed during the winter, though.

Yes (obviously not from the overlook). Before a bridge which crosses the southern spur of Diablo Lake, there is a camping ground at Thunder Knob Trailhead. Here you can access the water. A great place to swim and picnic. People also use canoes here.
