First, I booked the tour through Dolly Varden, rather than through the ship. Temsco didnt offer opportunity for direct booking. Still, saved about $70 a person through Dolly Varden as opposed to the cruse line. As far as the excursion...was a rainy day...thought either it would be off or it would not be good with the weather. Wrong, it was truly incredible. The visability was effected somewhat by the weather in the helicopter, but still was good. The helicopter ride was smooth, the pilot very good as a guide. As far as the glacier experience...just incredible...once in a lifetime. Great walking tour...pictures just incredible. Spend the money...go for it...dress for the rain you almost definitely will have there...you will not be sorry.
