I walked round most of Stanley Park. It is easy to disappear onto the trails in the middle, and find your way to a couple of lakes and plenty of tree life. Just try not to get stuck on the road at the top end – you can follow it for a while and not find lots of options to turn off onto trails.
Stanley Park is widely known to be a highlight of Vancouver, so I am not exactly breaking news by saying it is beautiful and popular. But it is so accessible from downtown, especially if you are staying nearby – the Westin Bayshore, for instance. I wasn’t, that’s a little out of my price range. But still, it is a great thing to have a beautiful big park so near to accommodation and everything else downtown Vancouver has to offer. Some pictures, for a flavour.
