They say opposites attract. Try combining the stunning glacial beauty of Alaska with the fiery tropical warmth of Hawaii in one seamless adventure. Start your trip with the adrenaline rush that comes with dogsledding, snowshoeing, heli-skiing, and watching the northern lights in a remote oasis in Alaska’s Denali National Park (the highest peak in North America at 20,310 feet) and then cap it off with sunset sails, rainforest hikes, and helicopter flights over lava pits from the quiet island paradise of Lanai, the least visited of the archipelago’s stunning islands.
