Visiting one of the most amazing swimming pools in the world – To Sua Ocean Trench in Samoa

To Sua Ocean Trench, Samoa

To Sua Ocean Trench

Ahhhh, the magical To Sua Ocean Trench in Samoa. Exploring this wonderful place makes you feel like you’re in the movie Avatar. This swimming hole is 100% one of the most amazing places to swim on our planet. The 30-metres deep ocean trench is surrounded by mind blowing lush vegetation and beautiful tropical garden.

The only way down to the crystal-clear water is via a long wooden ladder. The climb is long and the steps could get very slippery on days when To Sua gets crowded. (We’ve heard that Sundays are the busiest days as that’s when most of the locals visit the swimming hole). We visited the place on Saturday afternoon, during low season (December) and shared the place with only one family. (That said, while we were swimming, heaps of other people started arriving)

What to expect once you climb down

Once you reach the lower part of the steps you have a choice of either stepping to a platform from where you can jump or dive into the water or you could just take it easy and climb all the way down to the water 🙂

Once you are in water you need to realise that this is not a closed pool. The pool is fed through a cave that leads out to the ocean. Therefore, if you are not a strong swimmer you should stay near the ropes that run through the mid-way. (As you certainly don’t want to be washed out to the ocean with a strong current)

Other thing to note is that as the ocean will be constantly bringing in refreshing cold water, the temperature of the water won’t be warm. Secondly if you have a snorkeling mask or snorkeling glasses, you might as well take them with you as the trench is populated with tropical fish and the water is clear as crystal. 😛

What else is there to do

Few meters form the swimming hole is a viewing deck that is looking over the beautiful waters of south coast.

On the right side there are also some rock pools, blow holes and lava fields and on the West side there is a small beach, called Fagaoneone. We are not sure about the distance to that beach, but from the observation deck, it looks about 1-2km.

After taking in all the glory of this magnificent place has to offer, unpack your snack box and have a picnic under one of the traditional fales while enjoying the stunning views.

Getting to To Sua Ocean Trench

To Sua is located in Lotofaga Village, on the south-east coast of Upolu Island. Depending on which transport you are going to choose, it’s about an hour drive from the capital, Apia. To get to this magical place you can either:

For us the best way to experience and explore To Sua and the rest of the island of Upolu is with a rental car as this way we managed to explore this tropical island in our own pace while staying dry and protected from the sun and heat.

Once you have figured out your way of transport you have the option of driving either Cross Island Rd or Richardson Rd. The distance is pretty much the same but the Richardson Rd drive is much more scenic. In other words, this drive will take you through lush green forests, waterfalls, plantations and many traditional Samoan villages. Plus, it seemed to have less traffic than the Cross Island Rd. 🙂
