The self guided tour is excellent value for money, with easy to use and downloadable tour via an app to your mobile device! Excellent, easy ,interactive and can be used like we did everyday for 3-5 days, Asa guide and tour map, directions with audio and pictures, plus can take 1 hour or 3 and done at your leisure over 4 days. Far better than being in a crowded tour of 30 people and 50 tours off the cruise ships. Self guided tours on app the way forward and simple to use!
