What to see and do

  • Take in Kisimul’s spectacular site on a rock in the bay to see how it got its nickname
  • Follow in the wake of the clan chiefs who went before as you make the short boat trip to the island
  • Climb up to the tower house battlements for panoramic views of Castle Bay
  • Take our fun fact-finding quiz (also in Gaelic) while exploring the castle. Available on site
