Sleat is fantastic in good weather and out of the midge season.
Must do’s
South – Park at the old church and walk (a very undulating walk) to the very southern tip but make sure you head back via the lovely small beach at Camas Daraich/Craig Mhor (1/2 day if nice and warm full day)
Armadale Ferry point – Take the SeaFari http://www.seafari.co.uk/skye/gallery.php (1/2 or full day)
Take your time with plenty of stops and exploring on the square road out to the West Coast, there are old castles, beaches, rock pools to explore. At the northern tip Ord is a lovely spot, have a look around the private garden and walk out to the north. (1/2 day if nice full day, but take food and drink as there is no cafe’s or pubs)
IsleOrnsay has a nice gallery and beaches to explore (1/2 day)
Further north, Kylerhea Otter spotting area (1/2 day, full day if otters are about)
If wet there is always Armadale castle if you like that sort of thing
Others to look out for are just a little more north.
On the Broadford to Elgol road, 2 miles out of Broadford take the southern footpath to the clearance villages of Boreriag and Suisnish (1/2day – full day)
Elgol is great to explore and the ferry to Lock Coruisk in the heart of the Cullin should be on everyone’s bucket list, ferry back or take it one way and walk back over the “bad Step” (1/2 or full day)
