I have no idea what some of these reviews are on about! It doesn't smell or particulalry need tidying up, yes, there is some rubbish in the boating lake but that is the responsibility of everybody else to keep it tidy, not one group of people to clean up.
The boating lake is very reasonably priced, and the only way it could ever cost £13 is if you broke the rules and did not get your returnable deposit back. Which is your own stupid fault. I seem to remember it was £6 (two people) £3 deposit and £2 for extra passengers.
Beautiful scenery, great play park for the kids and a lovely lovely day out, so much to walk around and explore! Would highly recommed this to everyone with a family as a cheap, fun day out - if you take a picnic it doesn't need to cost a penny!
