Harvey Kersh

Movement & Somatics

Harvey has a way of making you feel completely at ease in your own body. His sessions are gentle, unhurried, and meet you exactly where you are. Guests talk about him long after the retreat ends.

Kasia Hamilton

Nutrition & Whole Food

Kasia cooks every meal and eats with the group. Her food is honest, generous, and designed to make you feel genuinely nourished. By the second day you’ll stop thinking about food and start just enjoying it.

Bespoke UK Sanctuaries

Every retreat is hosted in a handpicked UK location chosen for privacy, natural beauty, and uninterrupted stillness.

The Chapel & Waterfall — North Wales

A mountain refuge in North Wales. Sleep in a beautifully converted chapel within earshot of Dyserth Waterfall, seven minutes from the sea. Coastal walks, forest trails, and the raw beauty of the Welsh landscape.

How It Works.

Before.

It starts with a conversation. Clark gets to know you, what you’re carrying, what you’re hoping for. By the time you arrive, we’ve already started.

During.

Four days in North Wales. Everything taken care of. All you have to do is show up.

After.

You get home and the feeling stays. The group stays in touch — most cohorts do, and some of the best friendships start on retreat. You have a dedicated consultation with Clark to reshape your wellbeing structure around what you now know about yourself. The whole team is there if you need them. The retreat ends. The change doesn’t.

The Day-by-Day Flow.

The noise stops. You set down what you’ve been carrying and realise nobody needs anything from you. Someone else is cooking. Someone else has thought of everything. By the evening your shoulders have dropped and you’ve forgotten what day it is.

The day it goes deeper. Somewhere between the waterfall and the summit of Dyserth Mountain, with Snowdonia stretched out in front of you, the last bit of resistance lets go. By the fire pit that evening, the group that were strangers yesterday are talking like old friends.

Slower. Quieter. Harvey guides you back into your body in a way that feels like coming home. A beach walk to the Point of Ayr lighthouse. Long stretches of nothing you don’t have to justify to anyone.

Something shifted and you can feel it. You feel ready to take this energy home – not as a memory that fades by Tuesday, but as something you can actually feel in your body.

Their words, not ours.

I attend the recent retreat in Telfit Wales. This is my second experience of a retreat and it really solidified how important this investment in myself is. As a busy mum and full time professional it left me feeling refreshed and ready for the summer period and the second half of the year goals. The setting was lovely and the apartment space was really cool with opportunity to socialise or have time on your own. The food was lovely and what a treat not to have to think about what to eat or then make it. The yoga was the best I’ve experienced. Harvey is phenomenal..Clark and the team did a great job and I’ll be sure to sign up to another date early next year!

I attended an Insider Retreats last week and absolutely loved it. The daily yoga was both grounding and uplifting, and the wholesome, nourishing food made me feel truly cared for. Cold water immersion was my favourite part. As someone with health conditions, I was a bit worried about keeping up, but Clark made sure I felt fully included, offering thoughtful alternatives when needed without making me feel singled out. This meant I could join in at my own pace while still feeling part of the group. I left feeling lighter, stronger, and deeply rested. I would highly recommend this retreat to anyone looking for a space to reconnect with themselves, especially if you need a supportive, understanding environment to adapt around your health needs. A truly special experience.

From booking, to the amazing food prepared fresh every day, to the stunning accommodation and setting, to Harvey the most inspirational yoga teacher who has inspired me so much, to the special group of ladies I met in the retreat made it a truly unforgettable and special trip and I will definitely be booking again.

Having attended the waterfalls retreat this weekend I can highly recommend it, what a fantastic experience. The programme is full of wonderful opportunities to indulge in self care and reflection, not just yoga, Imagine being in nature, being in good like'minded and yet diverse company, being encouraged and supported, being given opportunities to try new things, being nourished with delicious food, being taught by an experienced passionate yoga guru, being relaxed because you do what works for you on the programme, being on high end accommodation and you will find it with Insider Retreats. I left feeling fully nourished after a joyful few days. I hope to do another with the wonderful team later in the year

Wow, what an all round amazing experience. From 1-2-1 chats with Clark on how to start to prepare my body for the food change to Penny's vast knowledge of menopause diets and vitamins. Also Jess for her beautiful soups and recipes. Harvey the yoga coach is my guru my dance partner and my warrier. I honestly think that this has changed my entire life. I've enjoyed everything about this retreat , I feel like a completely different woman. Looking forward to the next one 🙏🧘‍♀️

I've had the most amazing experience in Dyserth at the waterfall retreat. There was a lovely welcome from Clark and Jess the minute I arrived, Clark helping to carry my bags to the room which I really appreciated. The whole team, Harvey, Jess, Penny and Clark are all so welcoming I felt the warmth immediately. The yoga experience was so insightful, I enjoyed the in depth discussions as well as learning all the yoga positions. The strength I felt following the classes will carry me through the rest of my life. I have found the source and the source is within me to make changes and decisions. Harvey is a wonderfully intuitive teacher and I will continue to learn and practice yoga moving forward. The cold water immersion was invigorating, the food delicious and sharing life stories with so many people was inspiring. I loved the walks and the connections made with people whilst there will continue. I was very happy to share a room with Nutan and we got on really well, finding many things in common. Clark and all the team make this retreat an amazing, inspiring and wonderful retreat. I will definitely book another one in the future

I had such an amazing time in the Yorkshire Dales with Insider Retreats and 11 other new best friends. Full of joy, relaxation, views, music, walks, yoga, great food and so much love - my heart is full! The kindness and care that went into the planning of this retreat was evident from my first inquiry to my last hug good bye. The house was stunning and very comfortable. The time was planned with the perfect blend of activities, food and comradery. I can hardly wait to book my next retreat!
