Don’t plan on doing much after you’ve arrived in Vancouver. Let the brood run off steam in a local park (Stanley Park  is perfect if you’re based in the West End ). If you’re traveling with teens, a walk around Canada Place  provides a good introduction to the city.
Interactive displays at Science World  and Museum of Vancouver  will fill your morning. Older children will love exploring space at H.R. MacMillan Space Centre , adjacent to the Vancouver Museum, while young children will want to spend time at Granville Island’s Kids Market . If the weather is warm enough, bring bathing suits for the outdoor waterpark.
Kids will love Day 3, which centers on Stanley Park . Take a horse-drawn carriage ride, explore the Children’s Farmyard, and jump aboard the miniature railway. The park’s world-class Vancouver Aquarium  is a must (try to time your visit with the always-entertaining Dolphin Show). Break up the day with a picnic lunch at Third Beach  or a hot dog from Prospect Point Café.
Rise early and catch the ferry to Victoria . Find an outside seat on the starboard side and watch the Vancouver skyline and Coast Mountains disappear into the distance. Consider an afternoon double-decker bus tour of Victoria  to help everyone get oriented.
Explore the waterfront and find your way around to Fisherman’s Wharf for lunch at Barb’s Place , hoping that the resident seals make an appearance. Have your wallet out for afternoon visits to the Royal London Wax Museum and Pacific Undersea Gardens .
Go whale-watching in the morning from Tofino  then return to Victoria to spend the afternoon at your leisure, souvenir shopping along Government Street and walking through historical Market Square .
Return to Vancouver  for your homeward flight.
