Purchase the map

California Trail Map is a map (not an app). Map files are downloaded then used in the app that you choose.

Purchase the map using PayPal or a credit card. You will receive an email with a link to download the map after the transaction completes which usually takes about a minute. The link can be used to download the current version of the map until your subscription expires.

The map can be used beyond the subscription period but it will be out of date. For personal use, you may install the map on any iPad, iPhone, Windows or Mac device that you own.
