CORE | Release, Reset & Reclaim
You’ve outgrown the life you created.
You are ready for a change
You may have the career, the house, the relationship.
But there’s still a voice inside that whispers,
This isn’t it.
You feel it in your body.
The tension. The resistance. The fatigue of keeping up appearances.
The knowing that something needs to shift.
But you don’t know yet how to get what you want.
The CORE Retreat is a powerful, immersive 5-day journey that invites you to release what no longer serves, reset your internal compass, and reclaim who you truly are.
No more bypassing.
No more waiting.
It’s time to come home.
What is CORE?
CORE is not just a retreat. It’s our signature full-body wake-up call.
Facilitated across 7 countries, over the last 10 years with >200 graduates, CORE is the start of something new.
A deep dive into the roots of your patterns, emotions, and identity.
An invitation to shed the masks, speak your truth, and live in alignment with your values and desires.
We go beyond mindset.
We work with your body, your sabotaging patterns, your nervous system.
We unravel conditioning and bring to light the parts of you you’ve kept hidden.
Through movement, dynamic meditations, psychologic inquiries, coaching and raw honesty, you’ll break through what’s kept you small—and claim a version of yourself that’s grounded, clear, and alive.
This is not a spa retreat.
It’s real, raw, and alive.
And it will change you.

For me the CORE was one of the most impactful retreats that I have ever done in my life. In advance I thought it is an expensive retreat and now I think this retreat is worth every penny! It was a physical and emotional release and reset for me and I came out of CORE much lighter, physically I lost some kilos and emotionally I was very calm and serene; finally the voices in my head were quiet. I have examined and experienced my own judgments, patterns, and fears. As a result, I emerged as a new version of myself from the CORE. There was a new ME!

CORE is one of the most intense trainings I’ve ever attended. The speed, depth, and rawness made masks fall off quickly, and therefore I was able to go to places I had not yet discovered. I realized that my deepest fear is an illusion. CORE literally brought me closer to my core, allowing me to stand stronger and purer in life.

I recommend it because of the variety of exercises, the combination of tantra with NLP and innerchild work. The rituals embedded in the process. The presence of Karlijn and the assistance during the whole retreat made sure that every personal process was getting enough attention. Also the huge amount of aftercare moments, which has been helping my proces in the weeks after the retreat.

Anna Sati | Assistant
“My intention with CORE was to connect more deeply with myself in a period of change. Honestly, I also had the thought that I did not have much to learn…
What a big contrast with the deep emotional healing process I found myself in! I am so thankful that CORE has shaken me with so much love, brought me compassion, truth and radical acceptance of every aspect of my life. I look forward to assisting this CORE.”

Sanne ten Wolde | Retreat Chef
Sanne prefers to cook plant-based, sugar-free and with products from her father’s bio-dynamic vegetable garden. The dishes she cooks are therefore very seasonal. I love combining different cuisines with a focus on nutritious, innovative and caring. Her positive, bubbly energy can be felt miles away or actually, tasted in every bite. This week, she is the cherry on the cake.
“I believe my food & love can support building a more beautiful world in the most beautiful way.”

There are so many retreat offers, and I can imagine very well that for people who need help don't know where they should be. When they come out of this retreat it is truly a gigantic gift because bullshit is no longer possible.

Karlijn, meeting you last night after the dance was like you were an angel sent to help me in a moment of struggle. Your sincerity, your presence, your love, and your wisdom, all helped me to be grounded and understand something about the bigger picture of where I am and why my friends are here. Thank you with all my heart x

The Heartcore retreat takes place at Finca Vrij, a hidden gem in Zeeland.
More than just a retreat center, Finca Vrij is a place infused with love, attention, and care — and you feel it the moment you arrive. Surrounded by open fields and close to the sea, this self-built sanctuary is home to permaculture gardens, natural ponds, chickens, ducks, and two affectionate cats.
The land has been lovingly rewilded with thousands of trees and plants, creating a vibrant ecosystem. The retreat buildings are warm and inviting, the food organic and nourishing, and the whole space invites you to slow down and breathe deeper.
You’ll sleep in cozy shared rooms (max 2–3 people), with options for private rooms or campervans. There’s also a small shop with handcrafted, ethical products that support communities in Bali and Kenya — adding a touch of meaning to your stay.
