Stanley Park is about 1000 acres in downtown Vancouver on the harbour. You will enjoy many gardens with beautiful flowers and be surrounded by very tall trees.
You can sit and relax on the grassy areas or if you prefer, take a seat by the ocean on the many beaches you'll find in the park.
There are also activities such as the Aquarium and the farmyard. If you don't feel like walking, take a ride on the miniature railway that goes around the park. Expect a fee for some of these activities.
If you are just wanting to relax in beautiful surroundings, Stanley Park is the place to go.
