The Merlion Tower is the symbol of Sentosa and Singapore's tourism. The 320 fish scales on a Merlion are made of optical fibers. At night, they will change their colors and be striking and beautiful. The Merlion Tower is 37 metres high and has a bird's eye view of Singapore from the top. Only 180 visitors are allowed to climb the Merlion Pagoda at a time, and the fee is $8 for adults and $5 for children.
