Steep cliffs - don't fall over one!
If you get off the jetty, turn right and keep going you will eventually come to a narrow strip of land separating two beaches at the northern end of the island. Beware! The cliff to the left (which you may well not see) is a sheer drop with no warning and no fencing. We were on bicycles and could easily have gone over the edge. That said, it is seven years since I was last on Tory so this may well have been rectified by now.
Don't get stuck here !
The seas around Tory can get very rough. Apart from the obvious danger of seasickness, you may also be physically cut off from 'the country' or more accruately - mainland Ireland.
It has been known for the Island to be cut off in winter for up to SIX WEEKS.
This is very unlikely in summer, but you may lose a day - so don't rely on a 'must-do' connection to an airport the day you are supposed to leave the place.
If a ferry is not running, then it is sometime possible to get a ride on the Helicopter, but its costly.
