The fish and chips on the ferry is pretty good though, and there's always the chance of whale and dolphin watching from the top deck if the wind's light enough, maybe a late season basking shark...the ferry from Mallaig round the Small Islands is good for that too. Ferry top decks are by far the cheapest way to go cetacean spotting, and visibility is the best, so treat yourself, take some binos and make a day of it as a foot passenger on that Mallaig one (>Rhum>Canna) if you can. Have a magical 50th.

Sounds amazing. Yes I'll pop and get some travel sickness tablets. I'm not that good on rolling seas.

You have my sympathy, June. I puked horribly on the way back. And I too had foolishly eaten. I should have known better as I have a track record with ferries.

I've thought of a couple more places for the Girlinwellies:
Dun Carloway - that's intact enough that you can imagine people living in it.

And the Gearrannan Blackhouses - I thought that was going to be a bit cheesy. But seeing the chap weaving tweed on an amazing old loom that stank of oil, and asking him all about it - it was superb. Also there are some videos of people cutting and stacking peat - the piles are everywhere you go and it brought a bit of that hard way of living to life.

Plus I also liked the museum in the castle at Stornoway (good if it rains) - some of the lewis chessmen are there, and there's also a room that immerses you in a film projected all round with sounds of the island, I liked that a lot. And fossils.

I could go on.
