I recently did a walk around Arlington reservoir, as part of a longer walk from Berwick station to Eastbourne. I am constantly surprised at what I find near Brighton - Berwick is less than half an hour away by train, and yet this is a lovely spot, with great views, lots of wildlife, and nice cooling breezes on a hot day. It's also easily accessible by car, with a good car park, picnic tables and toilets.Strongly recommended for a good family day out.
