New Dates for Three Rivers Festival 2020

In anticipation of the likelihood that the COVID-19 pandemic will continue to require social distancing into late May and early June, we have decided to postpone Three Rivers Festival to the weekend of July 23rd-26th, 2020. This is our optimistic projection, and fervent hope that we are able to gather at that time.

This new date coincides with our annual Lugh-centred festival “Heart of One Festival” (HOOF) at Thornhaven. As a result, Lugh will be the patron of Three Rivers this year, and while we will retain the theme of “Renewal”, we will also celebrate Lugh and build a shrine in his honour.

May the gods and our ancestors keep us safe until we can come together.

Three Rivers Festival 2020

Save the date!

This year, the Thornhaven Sacred Centre will be hosting the Three Rivers Festival on June 4th to 7th, 2020.

This year’s theme, of renewal, has many layers. It holds the concept of the cycle, of moving back to the same place, but in a new form. It is about shedding the old, and moving toward the place of beginnings. It’s about tapping into the lessons and energies accumulated in the past to reshape in a new form. And it’s about embracing the end of something, to start fresh.

With the completion last year of the nemeton oaths, it is the end of one cycle, and the start of a new one. With it being the first year at Thornhaven, and with the ordination of a new priest, we will be witness to the beginning of something new, but which draws from the past all the strength, magic, and memory of the last 10 years of Three Rivers Festival.

Statement From The Mother Grove regarding founder Isaac Bonewits

In 2018, the late founder of ADF, Isaac Bonewits, was accused of sexually molesting a child. Just recently, allegations have been raised from among our membership that are similar in nature.

The Mother Grove publicly denounces Bonewits’ alleged actions toward children. We cannot and will not abide such actions. Children are our most precious asset, as they represent our future, and we have a sacred duty to protect them from harm, including teaching them about their own sovereignty.

For that reason, we also reaffirm our commitment to creating a culture of consent within ADF. The Mother Grove will work with our Human Services Specialist to create a consistent consent training program.

ADF may have begun as a single tree planted by Isaac, but in the years since, each new member has planted and tended their own tree. Some have chosen to plant a single tree, while others have together planted entire groves. Together, these trees make up the forest of Our Druidry. We stand now together, a forest of trees struggling in the darkness and shadow cast by that first tree.

There comes a time in the life of a grove where such trees must be felled, to allow for the growth and health of those which remain. This is such a time.

To preserve the health of our organization, we must cut out the blight that is Isaac Bonewits’ legacy. We sever the ties both historical and spiritual that bind us to him. For his actions against children, Isaac Bonewits will no longer be named as a beloved ancestor of ADF, nor is he welcome at our sacred fire.

May his memory and his dark actions fade with the rising of the sun.

We pray that those in need of support and healing find that swiftly, members and non-members alike, and remind members that they may reach out to the Members’ Advocate ( or Human Services Specialist ( for support.
