Although www.bluedome.co.uk is primarily an information resource about UK based activities it does have some good prizes on offer.
The site manages to have several reader competitions on the go at once and the competitions are usually easy to answer.
We have entered several over the last two years and keep going back to try our luck. One prize we really wanted was a fully paid for adventure holiday in the Outer Hebrides!
Mostly the prizes on offer are outdoor gear or equipment ranging from socks and gloves up to expensive jackets.
