To Sua Ocean Trench is one of the must-do experiences while in Samoa. In this post we explain everything you need to know before visiting.
It may sound a little bit silly but as a matter of fact there was just one reason for me to drag my family to Samoa for our yearly summer vacation: To Sua. A colleague at work had been there before and had shared fantastic photos of this freak of nature. I was getting really itchy looking at it, so beautiful and fascinating, and truly unique, I had to see it with my own eyes.
So when we travelled to Samoa, To Sua was definitely on the list of things to do around the island (Click here to see what other amazing things you can do in Samoa). So what exactly is To Sua?
To Sua – The Big Hole of Samoa
To Sua is a “big hole” (this is the actual Samoan translation) near the ocean that was created many many years ago through volcanic activity. The hole is around 30m deep and it’s filled with sea water that is directly connected underground with the nearby ocean.
You can access the water by a steep ladder, and there is a suspended rope and a platform to ensure that swimmers can conveniently enjoy the wonderful scenery by hanging onto the rope.
How to Access To Sua
To Sua is located on the south coast of Upolu Island near Lotofaga village.
The hole is actually located in a park-like setting, and you need to pay a small fee to enter the area. In return, you can swim in the hole, enjoy the beautiful tropical gardens, go swimming on a small beach, have the kids discover the shallow lava formed pools and walk the lava fields.
Plus, there are some fantastic views up and down the coast, so there are plenty of photo opportunities.
To Sua is well maintained with beautiful little picnic fales that provide protection and shade, as well as toilet facilities, and benches; ideal to spend a whole afternoon here.
Swimming in To Sua – An Unforgettable Experience
Climbing down the ladder is a bit of an adventure, considering you are far away from any medical services somewhere in a not very accessible area. However, the ladder is definitely very sturdy and the steps have rough surfaces so that you don’t risk slipping. Unfortunately, when I visited it was low tide and the water was cloudy, so snorkelling was not very good.
But still it was an amazing experience to swim in the water, surrounded by the tall black walls that are covered in green tropical foliage. The water would push and retract with the tide, so at any given time you would be gently pushed and pulled one way or the other. Just hold onto the rope that stretches across the full length and you can just relax, or swim around and discover the nooks and crannies of the hole.
The Lavafields: An Adventure for Smaller Kids
But there is more: If the hole is too daring for the kids, take them to the nearby lava pools instead.
These are just a couple of metres away and right by the sea. The shallow water is even warmer than the water in the hole, and there are some great natural things to explore. However, be mindful that the lava surfaces are sharp, so kids should wear some kind of protective footwear such as plastic sandals or reef shoes.
The lava fields stretch to the east from here, a wide area of flat surfaces, ponds, streams, caves and underwater channels. The landscape is surreal with its black grounds, the lush green backdrop and the clear blue water of the ocean.
There are many opportunities to test your courage – places you can jump in when the tide is just right, to dive under a lava bridge and come up again in a hole on the other side. There are blowholes that you can stand on to be sprayed by the salty water when the big wave comes.
The Lava Fields are Teeming with Fish
The water around us in the lava fields is teeming with life. There are shallow areas that rarely catch the tide, and you can see how fish chase each other in murderous pursuit, dashing out of the water and in again. There are crabs everywhere, alive ones, and those that have been smashed against the rocks by freak waves.
We are salty from the spray, hot from the sun, and loving it. What a great way to experience nature. To Sua should definitely be on your itinerary should you consider Samoa as your next travel destination. If you have already been, let me know how you liked it! More photos below.
To Sua is open daily from 7am to 6pm, adults pay around $7.50 AUD, kids $3.00 AUD (under 7s free).
