Are you Coming to Avalon and
Looking for a Tour Guide?
I offer Sacred Guided Journeys & pilgrimages for
Individuals, Couples & Groups... Exploring the Lost Stories,
Mysteries & Sacred Sites of Glastonbury, UK
The Energies of Ancient Avalon are Calling to many now…..
Have you felt this call?
This is an exciting moment…
You have felt the lands of Avalon calling, and now your pilgrimage can begin.
A journey to Avalon unfolds on many levels. It is an outer journey through sacred landscapes, ancient stories and powerful places… but it is also an inner journey of remembrance, connection and transformation. No one comes to Avalon by accident. These lands have a way of calling those who are ready to receive them… including those who may not yet fully understand why they feel drawn here.
For the past ten years, it has been one of my greatest joys to guide individuals, couples and groups through the sacred landscape of Avalon. Through storytelling, ceremony, history and direct connection with the land, I help open the gateways into its living mysteries… allowing you to receive Avalon through your heart, body and spirit.
Whether you are seeking a personal pilgrimage, a meaningful journey with your beloved, or a transformational experience for your group, I would be honoured to welcome you.
A Retreat Created Especially for You!
No two retreats are ever the same...
Every private retreat is lovingly created around you, your group and the experience you feel called to receive. Before your arrival, we will explore your interests, intentions and practical needs so that I can create an itinerary that feels aligned, spacious and deeply nourishing.
Your retreat may include sacred sites, ancient wells, abbey ruins, hidden landscapes, ceremonial spaces, contemplative practices and stories from the spiritual traditions woven through Avalon.
There will also be room for the unexpected… for the subtle guidance of the land and the magic that often reveals itself when we slow down, listen and remain open.
A Journey in Which You Can Feel Held
You are welcome to relax, receive and allow me to guide the entire day from beginning to end...
Or Cocreate the Journey with me!
-
I can hold the structure, lead the journey and create the ceremonial space so that you and your group can be fully present with the experience.
-
I am also very happy to co-create with you. If you are a retreat facilitator, teacher or ceremonial guide, we can weave your own offerings into the pilgrimage. There can also be space for members of your group to share their wisdom, gifts or practices where this feels appropriate.
My approach is grounded in collaboration, mutual respect and the understanding that we are all walking the land together. I will offer my guidance and experience while remaining open to what wishes to emerge through you, your group and Avalon itself.
Support Before Your Retreat
I want you to feel clear, prepared and supported before you arrive.
Depending upon the needs of your booking, I can offer:
-
Recommendations for accommodation in and around Glastonbury
-
Options suitable for individuals, couples and groups
-
-
Guidance for arriving in and departing from Glastonbury
-
Group transportation suggestions for sites outside Glastonbury
-
Practical information to help you prepare
-
A welcome guide and introductory video
-
Pre-retreat Zoom calls to help shape your itinerary
-
An introductory Zoom call with your group so that everyone can meet me before arriving
This preparation allows the pilgrimage to begin before we ever step onto the land.

A Pilgrimage into the Sacred Sites of Avalon & Surrounding Areas
Avalon is an ancient Island filled with Sacred Sites just waiting to be explored....
We will walk these ancient lands and you will hear forgotten stories and histories of these sites
while we connect deeply to their energies and magic.

The Holy Waters of Avalon
The Healing & Holy Waters of Avalon have flowed from the land for thousands of years....
These healing waters have been central to the ancient rites and magic and traditions of this land.
We will be exploring the different Holy Wells & Spring Sites in and around Glastonbury... and you will come into deep connection with these potent waters.... having the chance to touch, drink, and even bathe in their magic




Standing Stones of the Druids
Standing Stones and Henges were power places of worship and ceremony in the Ancient Druid Past, yet their true meaning and purpose is still shrouded in mystery....
We will journey to these ancient stone sites and you will meet these powerful stone beings. We will walk in their presence and be guided in how to connect with them, to listen to them, and be healed by their magic.




Ancient Sites of Worship
Avalon has a rich history woven through many timelines... and the Truth to many of these ancient "Christian" sites has been forgotten.. waiting to be remembered...
We will be exploring the Lost Gnostic past of Avalon by exploring her Ancient Cathedrals, Churches and Chapels. Sharing forgotten histories & stories of the Real Jesus, Mary Magdalene and other key figures of the Essenes.... and how these sites became entwined with Celtic and Druid Mystical Lore long before the emergence of Modern Christianity.




The Sacred Hills of Avalon
The landscape of Glastonbury is just as important as her History. Woven into the magic of this land are a series of Ancient Hills which are home to many legends & stories. And we will be making a pilgrimage to these Sacred Hills....
As we climb and walk these hills....We will be hearing stories of what these Hills meant to the ancient peoples of this land, why they were important, how these hills were used for ceremony & rituals, and even connecting to what still resides inside of them.

I can recommend suitable locations and guide you through the process. However, all private site reservations must be made and paid for directly by you or your group organizer. I am unable to make private bookings on behalf of another individual or group.
**Availability and access are determined by each individual site.
The Dragon Lands of Wales…
I also offer private retreats into the beautiful Dragon Lands of Wales.
Here, we can journey through enchanted forests, swim beneath waterfalls, commune with some of the oldest trees in Europe and visit sacred places connected with the Druids, early Celtic Christianity and the ancient spiritual landscape of Cymru. Many people choose to combine their time in Avalon with several days in Wales, creating a deeper pilgrimage through both landscapes.
If this calls to you, please let me know when you enquire and we can explore creating a combined Avalon and Wales itinerary.
