There are visitors to the Klondike Gold Rush National Historical Park and White Pass and Chilkoot Trails. Skagway has a historical district of about 100 buildings from the gold rush era. It receives about a million tourists annually, most of whom (about three quarters) come on cruise ships. The White Pass and Yukon Route operates its narrow-gauge train around Skagway during the summer months, primarily for tourists. The WPYR also ships copper ore from the interior.
