Cerro Chato (Chato Volcano), La Fortuna de San Carlos

#10 of 14 in Nature in Arenal Volcano National Park
Volcano · Hidden Gem · Nature / Park
Climb Cerro Chato (Chato Volcano), an inactive volcano covered in lush greenery. Believed to have erupted for the first time 38,000 years ago, the volcano last saw activity approximately 3,500 years ago--making it an entirely different proposition to its noisy neighbor, Arenal. Take one of the two routes to reach the top and see the lagoon of green water in its crater. Most regard the hikes as relatively tough for beginners, and the paths can become particularly muddy and dangerous when it rains.

  • The mid twenties special forces passed girls and guys are advised to climb this volcano. Anyone else, please do not attempt. You will regret it.  more »
  • I’m 33 and regrettably I’m quite out of shape. I’m tall (6’3”) which helped. The trail is basically four parts: 1) Green Lagoon to the trailhead - basically a road uphill - gets the heart beating...  more »
  • That volcano is simply amazing! Welcoming staff and cheap entrance for this great experience. The hike takes about 3 hours total. After you ascend and descend into the volcano (which is has a more extreme and steep slope) you can come down to a beach and swim inside the volcano. Yes, you've read it right. You can swim inside the Chato volcano. Be ready to make multiple stops and get plenty on water and comfortable shoes.
  • Fun and challenging hike!! We did not make it to the lake at the top but enjoyed beautiful views. Got to see a Mama and baby sloth!!
