I'm looking at ways of getting to the Tachä̀l Dhǟl visitor centre at Kluane National Park, 224 km from Whitehorse and 253 km from the Beaver Creek border crossing. I've found buses between Whitehorse and Dawson City along the Klondike Highway, buses between Fairbanks and Tok along the Alaska Highway, and buses between Dawson City and Tok along the Top of the World highway. Is there any bus company that operates buses between Whitehorse and Tok along the Alaska Highway? Presumably if they do, I could contact them to be dropped off (and, 2 weeks later, picked up) at Tachä̀l Dhǟl and/or another location along the same road.
(GoNorth says there isn't, but as they sell tickets Whitehorse – Dawson City – Tok the long way it wouldn't be in their commercial interest to link to a company that does run such buses, so I don't take their word for it.)
