If you're planning on visiting The Broads then this map is essential. This Active version of the Explorer series is the usual high quality 1:25,000 (4cm to 1km) map you would expect from Ordnance Survey, giving you all the detail you need, together with the added bonus of being encased in plastic, thereby making it waterproof, and let's face it, that is exactly what you need for any outdoor activities in this country. The map is divided logically in two, with the Southern Broads on one side and the Northern Broads on the other, with the only minor irritation being that central Norwich (situated on the River Wensum in the Southern Broads) is depicted on the Northern Broads side of the map.
If, like us, you are experiencing your first boating holiday on The Broads then this map is invaluable, not only for plotting your routes on the waterways but also for highlighting places of interest and, of course, the detailed information about footpaths for those times when you want to get off the boat and explore on foot.
We spent our week exclusively on the Southern Broads and nearly all of the free moorings are shown - we did notice one on the River Waveney between Burgh St. Peter and Beccles (Worlingham Staithe) was not marked. Also the map indicated that the moorings at Norwich Yacht Station are free, which they are definitely not. But these are only very minor quibbles.
One disappointment, nothing to do with the map, was that we initially ordered this map from Amazon but 18 days after the event were told that the order could not be fulfilled because of a delay in obtaining stock. We therefore ordered it directly from Ordnance Survey and received it within 5 days and a week before our departure.
