Did a day trip to the Glacier and Black Sand beach at the end of November. If there's more daylight hours, you'll see more. We were coming back and stopping at a waterfall in the dark. If we had the time, we would have done a 2-day trip. The company we went with was RE. It was on a big coach, not a minibus, which I don't care for. Even so, it was worth it IMO.
