"This UNESCO World Heritage site is carved into three main areas, or "cores." The Tanglin core is the oldest and the one visitors see first as they pass through the historic Tanglin Gate. The Tyersall-Gallop core is integrated into the park’s existing rainforest and the Bukit Timah core is home to a children's garden complete with treehouses, a suspension bridge, and farm. Visit the National Orchid Garden to see more than 1,000 species of orchids and 2,000 hybrids on display." - Ashlea Halpern
