Stanley Park, Vancouver
Stanley Park is one of the largest parks in Vancouver, if you travel across Burrard inlet to get to the north shore, you'll have to travel through this park. It has a long history & past tragic times, where the local natives where displaced from here where they had existed for centuries to make room for the europeans coming in. You can find historical plaques in various areas.
Lost lagoon up until the early 1960's, used to have small row-boats to rent, where people could enjoy a day on the lagoon, its a shame this is just not possible any longer. But, there are many trails to explore and discover. Some very nice beaches, and some, you can actually find a spot for your body on the sand. There is the Aquarium here, in the former zoo, this was thankfully almost entirely shut down, as it had become a miserable thing, and a sad place for many of the animals.
The mini train is still in service, and this is very enjoyable for folks with children.
During Christmas time, they put on quite the show with lights and different scenes the train passes through. During the winter of 2006 - 2007 Vancouver experienced quite the winter snow storm. Heavy winds with much snow, caused Stanley Park to lose many long standing trees. Clean-up is still going on at this time, and it's now february 2007.
Unique Suggestions: Go for a walk, rent a bike, visit the beaches, spend some time around the Lumber Mans' arch, here you'll get great views of the north shore,with the mountains. This is a favorite spot for Vancouverites and tourists alike. It's a large open space where large events happen during the summer months. Such as large open concerts etc...
Fun Alternatives: If you're not enjoying the natural side of things, and need some excitement in your day. Head east, just outside the park, you'll find many, many pubs and restaurants, and high-end shopping selections.
Stanley Park, of course! Its around 10km to get round the perimiter. If you get half way and have had enough, theres no getting out of it ;o)
