Hi Deborah
The Isle of Arran is a little gemstone.
We stayed at Seal Shore Camping and Touring Site. The pitches are almost on the beach on a gentle slope. Wonderful views of Ailsa Craig the seals etc. The excellent facilities, are a real home from home.The owner prides himself on having the best showers in Scotland. They are great.

Next door is a refurbished hotel that does both pub and posh grub. In the summer the sun terrace is a delight.
We tried the site at Lochranza which had restricted scenery so always use Seal Shore.
We have friends at Saltcoats. Do not make the mistake we made . We spent one night at Sandylands Caravan Park Saltcoats.After that we always stay at the CC site Craigie Gardens.
Also have a look at http://www.ukcampsite.co.uk/sites/reviews.asp?page=1&revid=3492
Arran is probably best described as all the best of Scotland in minature.
Cheers
