Son Doong Cave in Quang Binh province was featured on Google's homepage to commemorate the day Mr. Ho Khanh and the British Royal Cave Exploration Team officially discovered the world's largest cave on April 14, 2009.
Mr. Nguyen Le Phuc, Deputy Director General of the Vietnam National Administration of Tourism, stated: “The event of Son Doong Cave, with its outstanding global values, being honored on the Google homepage on April 14, 2022, is a source of pride for Quang Binh province in particular and for the Vietnamese tourism industry in general. As the world's largest cave, the grandeur, unique topography, and stunning scenery of Son Doong will undoubtedly provide visitors with impressive and breathtaking experiences. Vietnam has officially reopened international tourism with very favorable health entry conditions and restored visa and immigration policies to pre-pandemic levels. Everything is ready! We welcome tourists from all over the world to come and experience Vietnam to the fullest!”

Located within Phong Nha - Ke Bang National Park, Son Doong Cave is recognized by Guinness World Records as the world's largest cave, measuring 9 km in length, 150 m in width, and over 200 m in height.
Giant sinkholes allow sunlight and rain to nourish the pristine forest ecosystem, home to many species such as fruit bats and monkeys. The thriving primeval forest right inside this magnificent cave will amaze every visitor who sets foot in Son Doong Cave, even seasoned explorers.

The Son Doong Doodle depicts the scene of the giant sinkhole deep inside the cave, with sunlight illuminating the cave's landscape with various shades of green from the surrounding mountains and forests.
To support Vietnam's tourism recovery after the pandemic and attract international visitors, the Son Doong Cave Doodle not only appeared on the Google Vietnam homepage but also on the Google homepage in the following countries and territories: Argentina, Chile, Costa Rica, Dominican Republic, El Salvador, Greece, Guatemala, Honduras, Mexico, Moldova, Romania, Singapore, Sweden, Thailand, the US Virgin Islands, and the United Kingdom.
