April 11: We went to the grottoes at Rosh Hanikra, on the Lebanese border. The tour books say that the best time to visit this site is during stormy weather. The seas were indeed churned up when we arrived: rain clouds were pelting the off-shore waters. Accordingly, as we ventured through the grottoes, the ocean smacked against the rocks so forcefully that huge waves boomed into the caves (the explosive sounds were as loud as cannon fire) and soaked a few spectators. But what was really eerie was that the grotto openings would get extremely dark just before an onslaught of waves.
