This is the entrance to the famous Twin Lagoon. It's a shame that you can't bring your camera (unless it is waterproof) because you have to swim under the rocks to enter the lagoon. It is a nice adventure for those who can swim :)
I'm happy to have a fast enough camera to take 3 exposures with no tripod on a rocking boat. The sky was really blown out but I'm glad I was able to pull out some detail from the -2 exposure.
