A useful guide, particularly if you like to combine some pleasant walks with food and/or/drink. It's pocket-sized so easy to carry with you, and is well-written with plenty of nice photographs.
All the walks have all been selected with a view to visiting one or more restaurants/bars en route - with an idea of how long it takes to get to them and what to expect from the menu etc., so it's probably most useful for 1st time visitors to the Island, and people, like myself, who like to visit the more
out-of-town restaurants & bars.
For me it was a little too focused on the food & drink element, and not quite enough on the walks, so I consider it a useful addition rather than a must-have guide - so if hiking is your plan I suggest you consider this alongside other books that have a greater emphasis on the walks themselves, and carry a wider selection of alternatives.
