Although it was VERY muggy (you would expect it to be cool underground, hmm?) this was one of the most amazing parts of our DR trip. Our guide was exceptional (perfect English, very knowledgeable, friendly, funny) and the caves / lakes were breathtaking. If you go to Santo Domingo, you really should take time to see Tres Ojos. WARNING: there are A LOT of stairs and no ramps or elevators. Our guide said "once you go down, you have to climb back out." The stairs are not steep, but there are nearly 300 of them before you get back to where you started, so take a bottle of water and don't try it if you normally use a cane or a walker, you'll end up meeting the local ambulance personnel and I do not hear good things about medical services in the DR unless you have a lot of cash. ; )
