Getting there. Heriot Bay opens on the east side of Quadra Island, across from Rebecca Spit — the spit gives the bay its shelter and the Cortes ferry runs from the head of it, so keep clear of the ferry track on approach. Guests of the inn moor at a per-foot discount: $2.15/ft in summer against $2.25 for the public, $1.75 in May and October, $1.15 through winter. Always carry official charts and current Notices to Mariners.
