Trekkies take note: Knik Glacier is best known as the setting where a portion of Star Trek VI was filmed. You can get a partial view of the ice floe at Mile 7 of Knik River Rd off Old Glenn Hwy, but the best way to experience it is on an airboat ride up the Knik River. Knik Glacier Tours has four-hour tours departing at 10am and 2pm daily.
