I wish the weather wasn't so overcast during the day of our tour, but the craters were still breathtaking anyway! Mateo (our guide) was very knowledgeable and made sure that everyone was safe and comfortable. Without saying so, he was very aware when to stop and let folks who had a little more difficulty hiking catch their breath and rest. This isn't an intense hike, but the terrain can be tricky depending on recent rain/trail conditions. My wife and I are in decent shape, but when we were descending the trail (it was slippery) that my knees were definitely throbbing! This tour definitely isn't for you if you have bum knees or are not in good physical condition. I thank the crew for providing ample snacks, drinks, and especially, hiking poles, to make sure the guests were taken care of! I also appreciate Mateo for sharing local stories and legends to give us a newfound appreciation of the land.
