About the park
The lakes here were reservoirs before they were a country park. Derry drew its water from this high ground above the city, and the embankments, the sluice tower and the straight-edged banks you can still see are the giveaway — this is engineered water, not a natural lough.
When the reservoirs were no longer needed for supply, the ground could have gone the way most surplus utility land goes. Instead the site became a country park, and the activity centre grew up on the back of it as a not-for-profit — a community organisation rather than a commercial operator, which is why the prices are what they are and why so much of the programme is aimed at schools, youth groups and people who might not otherwise get onto water.
That matters more here than it might elsewhere. Creggan is a place with a hard history and a very strong sense of itself, and a hundred acres of lake and woodland on its doorstep, with kayaks on it and children learning to build rafts, is a genuinely good thing to have. The park calls itself Derry's best-kept secret; it is not far off.
Come for the walk if that is all you want — the paths round the water are free and the view back over the Foyle to the Donegal hills is one of the best in the city. But if you have children, book something. Getting them out on that lake is what they will remember.
