It is a guided night walk that begins at 5:30 pm. Each person carries a flashlight with them to be able to observe the path and surroundings. The guide in charge of the group carries a more powerful flashlight with him to be able to find the animals that are activated or sleep during the night. Also the sounds of crickets and frogs, the lights of the stars and the moon are part of the beauty that hides the night in the cloud forest. The guide carries a high definition telescope with him to better appreciate what is observed.
