It costs nothing to access Sentosa's beautifully manicured beaches. Pack a picnic, towels, and maybe a book or some games, and head to the beach for a fun – and free – beach day. Palawan Beach is a more family-friendly option, while Tanjong Beach, often less crowded, is tranquil and quiet. If you like watersports, you'll like Siloso Beach, which boasts numerous watersports activities (which are not free, unfortunately).
