On Hon Gom peninsula, there are two inland capes protruding into the sea (local people call it Mui Doi – Double Cape), the farthest cape is located at about longitude 109027’654 East and latitude 12039’477 North. It is recorded as the easternmost point of the mainland of Vietnam. About 600 meters away, there is a small island of about 3.4 hectares called Hon Doi (or Hon Dau) by the locals.
According to geological researchers, the land of present-day Khanh Hoa province belongs to the southeast edge of the ancient Kon Tum bedrock (also known as the Da Lat zone), which emerged from the sea surface from the Paleozoic era. The Himalayan forming cycle at the end of the Cenozoic era made the entire ledge of the Truong Son mountain, including the Khanh Hoa land, self-elevate and fracture in many places. The East side of Truong Son becomes a cliff facing the sea. The subsidence phenomenon also forms deep fault lines running along the coast, creating very majestic cliffs and reefs.
Looked at the map or looked through the aerial photos, the whole Hon Gom peninsula looks like a long dragon with its mouth (two capes of Mui Doi) open, grabbing the pearl (Hon Doi). On sunny days, Hon Doi appears like a rock-garden in the vast blue sea and sky. That said, because at Mui Doi - Hon Doi, there are rocks and clusters of rocks with very interesting shapes, reminiscing the images of camels, elephants, monkeys, mandarins playing chess, etc. To the northwest and west of the island, there are many beautiful small sandy beaches, convenient for visitors to experience swimming in the remote island. In particular, in Hon Dau, there are 2 rocks that rise sharply, like a mother and a child facing the sea, reminding many people of Vong Phu island on the east coast. It is because of these very interesting rocks in the shape of a human head, Hon Doi is also known as Hon Dau (Head Island).
Along the shoreline of Hon Gom peninsula, there are many rocks protruding from the sea surface or cliffs protruding from the mountain corner, named for the shape by the local people such as Da The cape (Card Cape), Da Tau cape (Ship Cape), Ca Nang cape (Manta Birostris cape), Hon Tai cape (Ear cape), Hon Trao cape (there are always waves crashing in, causing white foam on the rocky cape - translator), Black Dry Island, White Dry Island, Cot Buom cape (Boat Sail cape), Tham beach (Fine sand beach) Eo Gio cape (Wind cape), ect.…
In 2005, when Mui Doi - Hon Doi was ranked as a national scenic spot, this landscape started to be paid attention by the people of Tram Huong (Frankincense) region and tourists from all over the country. Since then, many tourists inside and outside the province have found their way to enjoy the wonderful scenery of Mui Doi - Hon Doi as well as the beauty of the sea surrounding Hon Gom peninsula. Sitting on the boat, we can watch the sea and the sky in a vast blue. A few fishing boats along the island edge and the sea corners contribute to the wild and charming beauty of an island-sea region. Far away are rocks with interesting shapes that make people from different angles think of different images depending on the association of each person. It is a very attractive journey for those who love travelling.
In recent years, many tourists have come to Mui Doi - Hon Doi, mainly by sea, but now many conquering and challenging groups have chosen to cross the sand dunes to reach Mui Doi, camping overnight to wait for the dawn. One of the most beautiful, most awaited moments is when the sun rises above the sea, shining its first rays on the double cape (Mui Doi). Many travel companies have also exploited tours to take guests from Nha Trang to catch the sunrise at the easternmost tip of the Vietnamese mainland.
