The 2024 retreat focus is for folks in the beginning stages of their fitness goals, so easier hikes and exercises.

private rooms with individual baths

August 26-Sept 2, 2024

Our fitness guides will lead you on daily 1-3 hr hikes to nearby trails near the shore and in midst of forest and mountains.  Expect to sweat and get a good cardiovascular workout while receiving nature therapy. We will also lead you in a kayaking tour in beautiful Puget Sound waters. Morning yoga classes will stretch your muscles and prepare you for a continued week of activity. Other classes consist of strength training, yoga, and meditation.


Local chefs will prepare meals for your specific needs, using mostly organic locally sourced sustainably raised food. After a week of eating clean, you will feel like a new person and lose weight. You will also learn about nutrition and mindful eating through lectures and discussions.

Learn how mindfulness promotes less inflammation in the body and reduces our fight and flight center.

You will be led in yoga and meditation and you will have quiet personal relaxation time at the retreat house. 


You can add on massage therapy sessions during your week at the in by local therapists. Cleansing food and drinks will support your body to detoxify toxins and chemicals that build up from our environment. Sweating during your workouts and re-hydrating with clean water will naturally detoxify your body.

Holly Peng MD

Family Physician and Integrative Health Coach


"I believe the foundation of "being the best version of you" and "living life to its fullest" is having HEALTH. And health is not the absence of disease but an optimal state of mental, physical and spiritual well being. I believe that everybody in this world can tap into that deserved authentic health and there is nothing more important.

Growing up with my grandmother (who lived until she was 105) I would hear her mantra in my ears -"watch over your health- without it, nothing else matters".  All the money in the world would be useless without your health. Without your health, you cannot be en effective parent, worker, or leader.

I believe furthermore that we were put on this earth to experience an exuberant life and the power to attain it is inside each one of us.

Here at Island Trek Fitness, we are dedicated to helping you achieve this exuberant life."
