Find an Overwintering Site


Use the map below to find an overwintering site by zooming in to areas you are interested in visiting. Important note: not all sites shown on this map have public access; many are privately owned or have sensitive resources. Please check on site ownership and arrange access in advance, if needed.

You can click each site to get some basic information such as the site name, lat/long, the last time the site was monitored, how many monarchs were counted, etc. Not all overwintering sites displayed on this map regularly host monarchs, some sites are considered “historic” –meaning they may have once hosted monarchs but no longer do. If you would like additional information about a site, contact [email protected] and we can provide a site-specific report.

Do you know about a site that’s not included on the map? Let us know–this is a living map and we try to update it annually with new reports. Also, please note that we have not included a handful of sensitive overwintering locations on this map due to concerns by private landowners. Please contact [email protected] if you are interested in a site you cannot find on the map.
