How often does the boat go fro Ross Castle to the island? It is impossible to find a timetable online! We are not interested in the lakes tour - only getting to/from Innisfallen island.
I have found out the answer myself now - there is no set timetable. Generally runs between 9 or 9:30 and 5. If there is a boat and skipper there at the dock, they will take you to the island (10 Euro per person; takes ten minutes in a small open motor-boat. They provide and required use of life jackets). If it is busy, they will go back and forth, and you can take any return boat with space. If it is not busy (like when we were there, on a nice Sunday morning in June), the skipper will wait at the island for you for 30 minutes - enough to take a decent look at the building ruins, but not to spend time for a picnic or such.
