Serious plant lovers will love the University of British Columbia. The prime attraction on campus, besides the must-see Museum of Anthropology, is the 44-hectare (110-acre) UBC Botanical Garden, home to more than 8,000 species of trees, shrubs, and flowers grouped into a BC native garden, a physic (or medicinal) garden, a food garden, and several others. (Spring, when the flowering trees bloom, is the best time to visit.) Energetic kids will love the Greenheart Canopy Walkway, a series of platforms suspended on wires at up to 18m (57 ft.) high, which move in waves as you walk along them. Nearby is the Nitobe Memorial Garden, a beautiful traditional Japanese garden considered among the top-five Japanese gardens in North America and one of the most authentic. Cherry blossoms peak in April and May, the irises bloom in June, and autumn brings colorful leaf displays.
