My Experience on the Gruta de Los Tayos
I was in the company of a group of friends, and after exploring the impressive Cascada Mágica del Río Malo Waterfall, which is likely one of the most powerful and largest waterfalls in Ecuador (if not the largest), we made a detour to visit Gruta de Los Tayos on our way back to Quito.
One of my friends had previously visited the cave and insisted that it was worth the visit, so we thought, why not give it a shot?

The beginning of the Adventure
This was our second adventure of the day in the Ecuadorian Amazon region, and we were completely soaked. The rain, along with the massive cloud of mist from the waterfall, got us drenched, including our boots. We had to change our clothes and put on swim shorts before venturing into the jungle with our soggy boots.
The property owner explained the trail to us at the entrance, and we were joined by a group of tourists. Since the welcome hut was right by the road, it was common to have visitors, so we couldn’t expect to have the cave all to ourselves.
We followed my friend who already knew the way, and there were signs with arrows in case we got lost. When we reached a strong river, we stopped. The owner hurried ahead and called us over to show us how to cross to the other side.
We held hands and crossed the river with her. Afterward, we waited for the other group to pass, and then we continued our journey deep into the jungle.

Finally, we arrived at the cave entrance, where another group was already taking pictures. My camera got foggy, probably because of the humidity and water dripping everywhere (the earlier waterfall adventure didn’t help either).
We entered the cave, and sometimes the water inside reached up to our knees. It was a challenge to keep the camera dry.
As I mentioned, we had our boots in the water, and sometimes it felt like even if we had rubber boots it wouldn’t make much of a difference because water still seeped in. If my boots weren’t already soaked, I probably would have gone without them (I had a bad experience in Baños where I slipped while crossing a small river and ended up soaking my backpack and iPhone. Since then, I always cross rivers without shoes to avoid slipping on slippery rocks).
Inside the cave, we saw the famous Tayos birds. Compared to the Kuankus’ Cueva de Los Tayos adventure I had in August 2022, where there were only a few Tayos left because it wasn’t breeding season, here there were so many. Hundreds, at least. We could see them flying around and resting on the rocks. They made a lot of noise, and they were quite big. The guide kept warning us to be careful and avoid them if they flew toward us. It was amusing.
After taking lots of photos and videos and truly enjoying the cave, which felt more like a corridor as it was only 60 meters long and 30 meters high, not like the closed caves we usually imagine, such as Cueva de Los Tayos of Kuankus, we ventured back into the wilderness and prepared for the return journey.

The return to the hut

Rewarding ourselves with a delicious lunch after an exhilarating and water-soaked adventure.
The way back was quick, except for crossing the river again. Finally, we reached the hut at the entrance, where my friends had a tasty-looking lunch, while I ate some pre-cooked food I had brought for the trip.
And that’s it! After lunch, we headed back to Quito. What an adventure! It was my first time driving from Quito to the Amazon, and I thought there would be many landslides on the road, but it turned out to be easier than I expected.
