I take from your question that you want a pre-made map with roads and waterbodies on it to which you can add points of interest.
I'm not sure about terms of usage for this site but if you use Arc GIS's Online Explorer, you can start with a base map and add items to it.
If you have a bit of GIS knowledge, you can use QGIS and OpenStreetMap data. Or just use OpenStreetMap and add your points directly on their site.
Hope that helps.
