Hi. We did the glacier hike on the 5/3 cruise. As point of reference, I had just run the Vancouver Marathon the Sunday before; my wife had done the 1/2 marathon. Another couple in our group had done a trail 1/2 marathon outside San Francisco on the layover on the repositioning cruise. We all showed up in old running shoes, expecting well maintained trails, which is what I believe the brochure said. None of us were experienced hikers, but there were people in our group who were. It starts off very easy. You walk along beautiful trails with big trees, plenty of shade, water rushing in streams in a few places. The guides maintain a brisk pace, stopping now and then to let people catch up while they point out facts about the forest and stuff. Soon, however, it became almost like mountain climbing. There was one area where they had steel cables up on the sides to keep you falling off the mountain and to use to haul yourself up. Other areas had to be climbed on all fours, especially for my wife and the other woman runner, since they are short and couldn't get their legs from one rock to another w/o using their hands to crawl up. The hardest was at the very top. Now, we did not know this, but maybe we missed it in the literature. The end of the hike is no where near the actual glacier. You end up with a great view of it, but you're not close to it at all. And getting to that point required climbing the rocks on all fours. BUT WAIT! There's more! Getting down was pretty bad. At the summit, the guides went down first so they could basically catch people as they slid down those rocks we had just climbed up. Remember, these rocks are wet from snow runoff. I made it down the first part so well they let me go ahead on my own, as did the other running couple. They were a little ahead of me when the wife fell, rolled into her husband and the both sort of slid down the rocks. His knee was a little banged up but they were basically OK. Just then, I saw a nice flat rock to make my next descent, but didn't notice it was wet and slippery. My old running shoes went right out from under me, I went down on my back, cut my shoulder, both elbows and a lot of my right hand as I grabbed for a tree or something, because I wasn't go straight down the "path", I was heading off the side of the mountain. Point is, I think you need to be in good shape. I think you need real hiking boots. You have to realize after all this you only get a picture of the glacier from a distance. Funny part was when we finished back at the parking lot, if you look out across the water you can see the glacier just fine. Oh, and things were so dicey on that first descent the guides took us back along another trail which is longer, w/o rocks or tow ropes, but which they said isn't always available due to runoff later in the year. We had a good time. But I think they sell this adventure as being easier than it really is.
