Laguna Verde - Green lake

The combination of paramo, volcano, mountains and water makes this place one of the best treks in Colombia. 

The green lake is located near to Tuquerres, inside of the Azufral Volcano in the Nariño State,
the colour of the lake is because the Volcano presents regular activity and that gives to the Lake a sulphur.

  

 Starting from Tuquerres a small town 2 hours from Pasto,You need to take a private car because normally there aren't buses .You can ask the bus driver where to get transport to the park when you arrive in Tuquerres.
You need to register at the admission to the park and then you are able to start. It is around a 12km round trip with a beautiful view of the classical Nariño landscape in the middle of the Andes Cordillera.

 The climate changes all the time, as is normal when you visit the páramos.

Try to wear waterproof clothing and good trekking shoes.

After a few hours of walking, we reach the top of the volcano with a majestic view of the lagoon and the valley covered for Frailejones and water.

After a 20 minute break we start to walk inside the volcano to the lake, the colourful landscape and nature makes this site one of the most beautiful that I have visited

Postscript: The park is not part of the PNN (National Natural Park) so the Indigenas and people who live there decided to close it  for a Natural Restoration, there is not even a day of opening, so check first before traveling.
