If time permits, you can buy a round-trip ticket on a boat in Lake Ness. When you arrive, you can get off for a tour and then take the next boat back to the dock. In the years after the 14th century, this castle, which is now a relic, has staged too many bloody scenes. The best place to observe it is from the cruise ship pier to the castle. When the cruise ship approaches the castle pier, it will have a good view of the castle from the lake.
