I made this map especially for the 'Simply Horses Mod' which was created by Lil Avii.

Here's the link incase you want it, or to research it; [http://www.minecraftforum.net/topic/1078787-125-simply-horses-mod-alpha-024-breeding-bugfix-release-ready/]

The map consists of huge paddocks, stables, a house/ranch type thing, a boat area that leads you to a market and an incomplete castle. There is also a cow shed, a wheat farm(non-automated), and a large arena style area back at the main area.

There are pathways to all but the market and castle, where you are led there by boat (head north-east from the bay facing out).
