If you are a subscriber, you are able to buy a ranch island of your own. Ranch islands do not show up on the maps.
To buy a ranch, go to any City Hall. On the walls there, you will find a Community Board. Clicking on this will bring up the Ranch window.
Here you are given a choice of sizes and terrains, varying from Tiny to Huge. "Grassy" isles grow Fruit and Nut trees. "Plains" isles grow flowers and plants. Which trees/shrubs/plants appear on a particular ranch island is randomly set when you buy your ranch. Nota bene: these trees, etc. are not pickable. Instead, their produce goes into the ranch owner's inventory once a day, beginning 24 hours after the ranch has been purchased.
Clicking on any of these options will buy you your island. To get to the island, go to the nearest dock. At the bottom of the Routes list, you will see, "Transport to your own ranch for $100." You can use this option to get to your own island from any port on the Isles. It is also possible to buy a Lifetime Pass which, once you own it, allows travel to and from your ranch for free. This pass costs $20,000 and is available from some of the harbormasters. Note: You can only buy a ranch from City Hall, and you can only sell it to City Hall. Players cannot sell ranches to one another. Also, only one player may own any ranch; players cannot "share" an island.
The first thing you'll see on your island is a Welcome sign. Clicking on this sign tells you what your ranch has produced since your last visit (if anything) and also gives you the option of sailing back to the port from which you came.
Horse sheds and barns, which allow you to keep additional horses.
Feed Silos, which automatically feed your horses.
Water towers, which automatically water both you and your horses.
Farm Plots, which feed you and generate extra produce which you can sell; the produce these farm plots provide is not found "in the wild" on the isles, and some of it is necessary for various quests.
Maple Trees, Milk Cows, Hen Houses, Sheep providing more items not found "in the wild" which you can then sell to other players.
Mines, which generate various metals and gems, five chunks/nuggets and three gems per day per mine.
Windmills, which generate money.
Training Centers which allow you to train your own horses at home.
Stores, where you can sell your own crafted items and produce, as well as horses and pets.
Adventure Kayaks, which allow you to travel to Foreign Isles where you can gather extra supplies for cooking, crafting, sewing and jewelry making (these isles do not have quests, treasures or wild horses).
For Each ranch house level that you upgrade to, you are allowed 15 additional inventory slots for more room.
What kinds of buildings you can put on your ranch sometimes depend on the level of ranch house you own. There are eight different levels. At the lowest levels, you can put up horse sheds which allow you to own one additional horse (over the five you are allowed at the start of the game). It is not until you have erected a level 4 Ranch House that you may place a Horse Barn, which allows you to own three additional horses per barn. (Gold Barns are also available, but at level 7, which allow more horses per barn.)
You may place as many barns, as well as many other types of structures, as you want, but some structures are limited to one per island. When you click on a paddle to add or demolish a structure, you will be given a list of what can be put on that spot.
