We did this tour as part of our 7 Days/7 Nights Deluxe Alaska Sampler railroad package. We were not sure what to expect, but it turned out to be one of the better activities of the whole trip. The staff were very professional, made sure we were properly outfitted, and provided safety instructions before we got on the raft. They did all the rafting, while we got to sit back and enjoy the ride. We got close enough to touch the glacier and the rest of the river trip was beautiful. It had rained that morning when we left Anchorage, but the afternoon in the Spencer area turned out to be a gorgeous day for rafting, with calm water. We were also given snacks (it was advertised as 'Hearty Alaskan Snack' if that's what jerky, pretzels, water are - would be nice if they included nuts as a healthy alternative for vegans). We got picked up by the train when we were done. Definitely recommend for the experience and wonderful scenery.
