Good trail well maintained. Some good, steep climbs to keep the heart rate up.
To hike, you must pay ($15USD each hiker).

Such a wonderful experience.

Beautiful waterfall and a nice place to take a dip in the water! Stairs have all been replaced since the last time I was there. Much nicer and easier to climb up and down the stairs now.

Beautiful waterfall. Easy paved walk on stairs.
Nice for a quick and easy adventure.
Bring a suit to swim at the bottom!

The waterfall itself is a majestic sight. If you are into waterfalls this is a good stop and people can dip in the plunge pool. Apparently there are lifeguards who will prevent swimmers from getting too close to the fall itself. But from a hiking / nature viewing perspective this is a rather boring place. Travel is confined to the 500+ stairs down. Very little space at the bottom. It seems all tourists to Costa Rica are at the bottom simultaneously! Other than some fish in the stream no wildlife was seems.

The marked trail doesn’t afford good views, being in tall reeds / woods almost all the way. Lots of tourists too. Not much wildlife viewing. Very easy and still nice. Much better is the shorter hike directly up slope to a shelter, shown as the short white path toward east on AllTrails map. Less traffic, saw a river of army ants, cute birds, orchids , and almost constant view of the volcano.

Great trail with family

This trail is officialy closed : barbed wires limits its entrence and sometimes a guard patrols there and ask you to leave. You can however get around the wires and hope that nobody guards the entry.
You can access the trail through a private path belonging to GreenLagoon cabinas (they dont explicitely warn you that the cero chato trail is closed but will charge you 5000 crc/ 10 usd entry fees) but there might be another way to access the trail.

The trail remains difficult : since its closed the path is not maintained and the forest is ALWAYS muddy so you mainly have to climb your way down to the lake (super steep and slippery). Took us 6h (1h of break included).

It however TOTALLY WORTH IT : funniest and most beautiful hike I ever did (plus you can swim in a volcano).

This 3.5 hours guided hike in the rainforest (in part on very high suspension bridges) was the highlight of our Costa Rica trip. Our guide (Gabriella) taught us a lot about the flora and fauna and got the kids interested through the whole hike. We spotted many interesting plants and animals (a snake, a tarantula and other big spiders, weird plants).

Unfortunately this trail is closed , supposedly for governmental reasons:-(

Gonna need your feet AND hands for this one.

So cool though! Can officially say I’ve dipped into a volcanic crater lake. Steep up and down into the crater, hopefully it’s a clear day so you can see the entire thing.

Cost 15 dollars, pretty but not worth it. 500 steps down, 500 steps up nothing else to do...no flowers in the orchid garden were in bloom. In high season with warm weather, tiny swimming area just down from the falls would have been too packed to move. The waterfall is nice, but not spectacular and not for that price.

Checked in at the green lagoon to get passes, ten dollars per person. Had to go around the barb wire fence.
Challenging hike lots of climbing, took us 4h total at a fast pace. It rained the whole time and it became slippery on the way down. Worth the hike but dont expect the view in bad weather.

Easy trail, but beautiful!

Gorgeous waterfall! Took the stairs down and back up once ready. Man made straight forward trail - there are about 500 stairs down to the falls (ballpark, or so I was told). No guide needed. It is highly trafficked. When I went there were a lot of people there.

Recently had the pleasure of completing the longer loop. Moderate trail. Was able to see tucans, howler monkeys, wild turkeys, and tarantulas galore! Was not the clearest day ever to get the best views of the volcano itself, but still well worth the trip!

Great hike. Make sure you have good shoes because it will get slippery. Bring plenty of water.

awesome but hard trail. it gets more difficult step by step. as we started laid, the crater it self was filled with clouds.
paid 10$. no problem to enter national park.

Awesome hike! If you want to escape from the too easy, touristy hikes, do this one! It is a little hard but very fun. Bring proper shoes though.

The guard was not there today so we were able to hike all the way to the crater!! It was so foggy that we could not see to the other side, but awesome to say we swam in the crater of a volcano! You pay $10 per person at the hotel near Arenal Observatory then hike the Fortuna Observatory trail. You will cross to the illegal part of the hike once you go through the opening of the barbed wire. You can also start this hike from the La Fortuna waterfall which is $15 a person and a shorter hike I believe.

We had heard that Cerro Chato was closed but decided to give it a try we decided to go through Arenal Observatory Lodge, we were warned hiking Cerro Chato was illegal and would not give us information. But we found our way, unfortunately they have a guard at their property line to turn people back so we weren't able to go up. Seems like Cerro Chato is no longer an option in Arenal.

Wild hike!!

Good trial, beautiful views, but expensive

Lots of steps up to the top, the fog was over the lake so I couldn't see it but it was a very fun trial really accessible from town about an hour each way

really beautiful quick hike

The longer loop was a good trek. It is easy to follow and passable for almost any skill level, including one on our group who had a hip replacement less than 6 months ago.

This was by far the hardest hike I have ever done, but it was so worth it. I recommend going in the water of the lagoon. The feeling of the ice cold water after the long hike was refreshing not to mention pretty exciting knowing we are in a volcanic lagoon!!

One of my all time favorites. We got here early in the morning during rainy season. Trek up was very difficult because of how slippery and muddy everything was, but the elements made it more enjoyable honestly. The views from the top were beautiful and then you take a pretty steep hike down to the crater. We got down to it, a lot of fog was rolling in and it made for a super eerie yet serene setting.

This hike was absolutely breath taking. One of the highlights of our trip.
