I visited a friend in Lisbon about 3 weeks ago and this had to be my FAVORITE place. It was raining the day we went and there were few tourists. We ducked into some of the grottos to keep dry...unfortunately, we didn't take our flashlights. But bumped into a German couple emerging from the Initiation Well..they gave us the heads up to keep going and our lack of night vision was rewarded with the Well...how cool!
