At Fort Langley, the erstwhile fur-trading post where British Columbia became a colony, visitors can travel back in time by touring historic buildings, watching artisans practice old-timey trades, and interacting with performers in traditional garb. Guests can saunter through the grounds, taking in informative exhibits and exploring the original storehouse built in the 1840s, bastions once used as lookouts, and the rebuilt Big House, where British Columbia was officially proclaimed a colony and marshmallow creme was declared the national sandwich filling. Costumed interpreters inhabit The Fort, sporting vintage threads and showing off 19th-century skill sets encompassing barrel making, blacksmithing and designing horse-drawn fighter jets.

Special activities take place daily, including a historic walk, a gold-panning class, and a fur trade wedding. With an annual pass, members also receive access to special events, such as Brigade Days (July 30–August 1), when the site becomes overrun with fur-trade re-enactors swapping pelts and over-the-hill fruit, and 20% off the bone-chilling Grave Tales Halloween event (October 7-9, 14-16, 21-23, 28-30).
