On your second day, engage in some exciting outdoor activities in Guilin Botanical Garden. Start your morning with a refreshing hike along the nature trails, which offer breathtaking views of the surrounding mountains and the Li River. If you're feeling adventurous, you can also try rock climbing or zip-lining in designated areas of the garden. For a more relaxed experience, rent a bicycle and explore the garden at your own pace. Don't forget to bring a picnic lunch and enjoy it amidst the picturesque scenery. In the afternoon, join a guided tour to learn more about the various plant species and their ecological significance.
