California Marine Protected Areas

Important: As of January 1, 2019 new MPA regulations are in effect.

This web mapping application is designed for use in mobile devices such as smart phones and tablets. With it, you can identify Marine Protected Areas and your proximity to them. If you have trouble viewing the map, find the Marine Protected Area that interests you, follow the details link and then follow the image link.

This map is not intended to be used for navigational purposes.

Enable location services

Enabling location services will identify your location in relationship to MPAs, but is not necessary to use this map.

For iPhone or iPad users, go to the main screen and open Settings → General → Location Services and turn it on. Then scroll to the Safari application (if available) and turn it on. If Safari is not listed, you do not need to do anything else.

For Android users, navigate to Menu → Settings → Enable Location and turn it on.


Currently this map application works best in the iPhone, iPad or Android devices.

Touch panning and zooming are not available on many devices. After starting the map, click the gear icon then expand the settings panel. You can then enable pan buttons for the map.

Blackberry devices older than the Torch probably will not work at all. Newer devices may work to some extent.

Windows Phone 7.5 (Mango) devices should work. There is a known problem in version 7.0 that causes the map to extend beyond the visible screen. Additionally, the graphics drawing layer is not supported in 7.0.

Feature phones with web browsing probably will not work at all.

If you navigate away from the map web page, you may not view the same map location upon returning. Most links will keep you on the map page. The exceptions include the link to the Marine Protected Areas Home and any link to Regulations. Your browser or device back and forward buttons will cause you to navigate away from the map page, and your map location will be lost.
