The museum is located in the Roe House at Roesland on North Pender Island, one of the properties that form the Gulf Islands National Park Reserve.

The purpose of the Pender Islands Museum is to acquire, catalogue, display and preserve historical artifacts and archival records related to the Pender Islands and to make them available for public viewing, education, and research.

Occasionally special programs are offered for locals and visitors alike. These may include garden parties, museum tours, demonstrations, sponsored lectures and display tables at local events.
