Wander 15 metres in the air while you walk amidst the higher branches of century-old trees in the David C. Lam Asian Garden. This incredible high-flying adventure is the Greenheart TreeWalk, open from spring to the end of October. You’ll discover flora and fauna here that are invisible from the ground. Take the Tour: Every hour, on the hour, a 45-minute guided tour of the Canopy Walkway begins. You can upgrade to a specific Botanical Garden tour by booking in advance. Just call 604-822-4208.
