Situated in Stanley Park, it seems that there are annual tickets (I don't remember very well). We bought them once. Go to the park must also go here to see, go out to play where is worthwhile, some places may only once in a lifetime.
From Richmond to Vancouver Center by overhead train, turn from the subway station to No. 240 bus stop 5, then get off at Denman St and walk to Stanley Park for about 15 minutes. The road is full of scenery. Aquarium Adult Ticket 14.95 Canadian dollars, known as North America's third largest.
