Like all parks in Vancouver the views at the bridge and the mountain are amazing. Rodrigo, our guide, was friendly knowledgeable and saved us so much time not having to wait in line, especially the tram ride down Grouse Mountain.
The fish hatchery sounded kind of boring and it kind of was, but the views are so beautiful especially on the short hiking trails.
A couple of tips/information: Bring a light jacket ( I went in August) not so much for cold, but wind. The bridge isn't that long and it somewhat shakes, but it's safe. The annoying part is that people like to suddenly stop and take their photos.
Take the free ski lift to the very top of Grouse Mountain you won't be disappointed.
I just wish there was more time at each stop (perhaps 20-30 minutes more) there is so much to see and do.
