Just a short flight from Singapore, nestled beneath the crystal-clear waters of a peaceful tropical bay, lies a truly one-of-a-kind attraction: an underwater mailbox. Located off the coast where vibrant coral reefs flourish, this waterproof mailbox allows water adventurers to send postcards from three to five metres below the sea’s surface. In fact, this mesmerising underwater mailbox is part of an artistic marine conversation project within one of Bali’s most beautiful underwater sculpture gardens. Located below the shores of Jemeluk Bay in Amed, here’s why you this unique attraction needs to be on your bucket list.
What makes this underwater mailbox a unique diving experience?
Snorkelers and divers can experience underwater adventures a little differently in Jemeluk Bay in Bali. Travellers can send a physical waterproof postcard between 3 to 5 metres below the water’s surface. Part of Jemeluk Bay Underwater Gallery, the iconic attraction has contributed to the area’s charm as dive site for nearly two decades.
Interestingly, the bay’s calm waters and good visibility up to 25 metres make it ideal for diving and snorkeling—allowing visitors to admire vibrant coral formations, tropical fish, green sea turtles, and the stunning underwater gallery.
Particularly, the underwater mailbox resembles a traditional Balinese temple near a distinctive yellow dive buoy. The letterbox itself, allows divers to mail postcards underwater, making it an eco-friendly activity like no other. Normally, visitors use oil-based markers to write messages on the postcards before placing them in the letterbox’s underwater net. Following this, trained divers collect these postcards regularly to ensure delivery globally. Be sure to buy a waterproof postcard nearby before your dive!
Meanwhile, the Jemeluk Bay Underwater Gallery remains a popular attraction in East Bali. It’s known for its living sea sculptures such as a giant baby head, mythical Hindu water nymphs, mermaids, treasure chests, and more Balinese barong figures, submerged alongside coral walls thriving with rich marine life.

Plus, Malaysia holds the record for the deepest underwater mailbox at 40 metres below Pulau Layang-Layang. Meanwhile, the world’s most famous underwater post office is in Vanuatu.
