Eilean Donan Castle Yesterday, 7/15/14

The gentleman at the Eilean Donan Castle ticket booth was so nice when I asked about the tidal times and depth of the water. He assured me that in Highland Passage, Ciarán and Mac would indeed have needed a boat to get across to the castle even at low tide. He checked a schedule inside the ticket booth for the exact time when the tide is the lowest, and then showed me how high the water gets at high tide.
