The To Sua Ocean trench has been dubbed by international travel agencies and international travellers as one of the "top swimming holes in the world". 

A video posted to TikTok, instagram and Facebook by a travel creator based in New Zealand, Daniel MacKinnon has gone viral with over 900,000 shares and million views, showcasing the beautiful scenery of Samoa's nature. 

The video shows MacKinnon searching for the top swimming hole in the world and discovering that To-Sua was number one in the list of all the swimming holes in the world. 

An international American pay television channel called Travel Channel, owned by Warner Bros also featured the To-Sua trench as the top swimming hole in the world. 

"Instead of another trip to the beach, have an adventure tracking down these breathtaking Mother Nature-made pools," Travel Channel wrote. 

"From an electric-blue waterfall in Costa Rica to a 100-foot-deep grotto pool on a volcanic island in Samoa, here are 20 of the most unique, secluded, and hard-to-reach swimming spots in the world." 

To-Sua was on top of the 20 different places cited by Travel Channel. 

A well-known international travel guide website called "Culture Tip" also featured the To-Sua amongst the numerous amazing swimming holes around the world. 

"Some of them are extremely popular, while others fly under the radar," Culture Tip wrote. 

"With flowing waterfalls, turquoise waters, and gorgeous sandstone cliffs, here are some of the best secret swimming holes you will find in North America, Asia, Europe, and Australia.

"Visitors will locate the To Sua Ocean Trench, situated in Samoa, on the island’s Main South Coast Road. The stunning attraction features “a unique land formation consisting of two giant holes joined via an ancient lava tube cave.” One of these holes is To Sua Ocean Trench, a 30-meter-deep (98.4 feet) swimming hole that features turquoise waters, lush greenery surrounds, and access via a ladder."

Located in Somoa’s Lotofaga Village on the island of Upolu, formed by a big basaltic shield volcano, To Sua Ocean Trench is an all-natural swimming hole with a visitor-friendly ladder and small dock (translated to ‘large swimming hole’). Surrounded by lush gardens, this trench is filled with fish, crabs, and lots of other marine life.

With a depth of 30 meters, the water of To Sua Ocean Trench is clear and has a beautiful blue colouration. Most likely, its origins date from a time when volcanoes erupted and covered the nearby shores with lava making the ground collapse, leaving behind a 30 meters deep hole, which connects with the ocean through underground canals.
