Please note, there are many more resources available than I can possibly include on my website. When you are searching on the web, you will come across a mix of resources that are very good, resources that are quite poorly-informed, and resources that are somewhere in between. Please be aware.

These are listed in alphabetical order. This list is just a start and is not complete!
How to find others not listed? In 2011, the Pagan Newswire Collective provided extensive coverage wherever possible; you can do web searches for national, regional, and local Pagan festivals and even for local Pagan meet-ups; many groups list events on Witchvox.
Please note that I do not recommend or endorse any of these, and that I do not necessarily have personal experience with any of them.
