While I was in Vancouver I met a friend at Queen Elizabeth Park, which is a “horticultural jewel” according to the City of Vancouver's Parks and Recreation Department and I would have to concur.
The park is at the geographic centre of Vancouver. The park is a former rock quarry when settler population began in earnest in the 1870s.
The park consists of 130 acres. At the top of the hill, Little Mountain, the highest point in Vancouver proper at 500 feet above sea level, is the Bloedel Conservatory, a geodesic structure with a lovely view over the city below.
