Behind Marina Bay Sands hotel lies a 250-acre park with beautiful gardens and a marina reservoir. The park, Gardens by the Bay, is made of reclaimed land and open to the public. The main sites are a Supertree Grove, giant futurist vertical gardens shaped into a tree that light up at night, and a Flower Dome and Cloud Forest Dome, two conservatories that have permanent and changing displays of local and international plants. But the gardens themselves are worth exploring, as these photos show.
