This tour will operate by van, helicopter and airboat. Guests must be aged 7 years or older and are advised to dress in warm layers with a hat and gloves. A full safety briefing will be provided at the heliport and guests will be fitted with glacier boots and headphones. Flotation devices will be provided before boarding the airboat. All times are approximate and for security purposes, no bags are allowed on the flight. Due to weight and balance limitations, as well as passenger safety and comfort, passengers weighing 250lbs or more (fully clothed) will be assessed and may incur a weight surcharge to reserve adequate space onboard the helicopter. Guests weighing 250lbs or more should contact the Shore Excursions Office onboard at the beginning of the cruise.
