West coast Scotland can be plagued by Midgies in June - August, to the extent that its not possible to stand still outside on calm days.
This is a very significant factor if planning to camp or have romantic evenings outdoors.
For lots more information, please see my Scotland Page Tips - Warnings where there is also links to external website with details and help.
Ok - If you are going to Skye - look at the weather forcast first.
In dry weather it can win your heart. With the sun and clouds draped over mountains, the coastline with its short grassy turf can be paradise - hence everyones photos on VT.
In mid summer, midgies swarm, unless the wind picks up (more than 4 mph is needed, and if you're sitting or camping, no hope).
In rain, with low cloud and no good indoor attractions, you can be at a loss. Many decide to turn and cross back over the bridge the same day ,which is sad.
So just be flexible, see the weather forcasts 2/3 days before, and don't trust to the weather gods.
Unless you can afford to eat in the lap of luxury at The Three Chimneys, eating out on Skye can prove to be a massive disappointment.
In particular, Portree, where desperation can lead to costly and tasteless rip offs.
Where else would people buy their fish from one shop and their chips from the other, because they cannot cook. The restaurants are worse. Fancy menus and "fresh, local fish" do not make it to your plate as good food. Maybe I'm fussy. I am a chef.
Skye, despite the Bridge, remains an island economically, and can be very costly, if you haven't planned.
Arriving in Portree with nowhere to stay could well mean a very expensive hotel stay, once you've walked round and around all the full B&Bs.
I believe you should purchase as much as possible on the island, to assist the local economy. This includes food from the small shops, petrol from expensive stations, and hiked up accommodation charges in peak season. But, be prepared, and watch your spending. A night in Portree Bars could cost you a trip to Lewis - and you'd never forgive yourself.
I mentionned it in a recent page on Mull, but here goes again. Skye is full of mushrooms and have lots of different type. I have read recently that Scotland have the most poisonnous (mortal) mushroom in the world, and it is difficult to recognize as it looks so much like an edible type. Make sure you know them before you start adding them to your gastronomic dinner!
