Salto is the second largest city in Uruguay, resting on the banks of the mighty Uruguay River in the northwest. It is famous for its warm thermal springs that bubble up from deep underground.
Families come to soak in the warm thermal pools, visit the big Salto Grande dam, and enjoy juicy oranges from the local farms. The riverside parks are perfect for a picnic.
The naturally warm thermal pools are like giant outdoor bathtubs where kids and grown-ups can relax together.
The wide Uruguay River is great for boat rides, fishing, and watching the sun set over the water.
