Great free day out for families with children of any age. Get the picnic packed, throw in a football, bread for the ducks and off you go. The play park is great for all ages, however, slightly limited for the 3 and under bracket. Its main advantage is the safety as it is all fenced in so even when busy you could easily spot if your child was heading for the exits. So much space for ball games and picnics that you are spoilt for choice and even at its most busy you can always find a quiet spot. You can always head for the band stand and have your picnic there if the weather isn't looking great. The band stand's novelty value for very young children tends to work as well. A walk, or bike ride, round the lake is great - flat, buggy friendly, toddler friendly, bike with stabilizers friendly and not too long. There is a cafe by the lake but to be honest we've never found the need to use it. Oh, I said free didn't I - not quite, there is an icecream van and I don't know of a child who can get past one of those without nattering for a lolly or icecream, so a couple of pounds for the icecream treat. You can venture over the road to Tropical World (a good wet weather plan) - reasonable entry price but remember, its tropical, make sure you're not wearing your arctic fleece. Without Tropical World you can very easily spend a full day at Roundhay for the price of an icecream - you can't get much better than that for the summer hols!
