Into The Wild

A Vinyasa,  Yin Yoga & Hang Music Retreat
January 11-17, 2025

Are you longing to get away from the stresses of these challenging times? Enjoy a week of inspiration and gentle stimulation for your senses. You will reconnect with yourself through yoga amidst the wonders of vibrant nature and wildlife. Our retreat immerses you in the lush beauty of the vibrant Peninsula de Osa, one of the last untouched tropical paradises in the south of Costa Rica.

Enjoy tranquil days with like-minded people, sharing laughter, tears, joy and movement. Nothing (well, maybe falling in love) will lift your spirit faster than a week like this.

Puerto Jimenez, Osa Peninsula

Go off the beaten path to a place where your alarm clock is the call of a playful howler monkey, your lullaby, cicada song carried on the Pacific breeze, where the mangoes are sweeter than honey, scarlet macaws more common than pigeons and where, when it comes to your yoga practice and wellness, there’s no such thing as a one-size-fits-all approach. 

Reconnect with nature

Nereus retreat center promises a sublime setting for your yoga retreat where the rainforest meets the ocean. Located in Costa Rica’s famous Osa Peninsula – a region described by National Geographic as one of the most “biologically intense” places on the planet – the area is bookended by the deep blue waters of the Pacific to the west and the Golfo Dulce, or “Sweet Gulf”, to the east. While the Osa comprises only 3 per cent of Costa Rica’s total land area, it is home to more than 50 per cent of the country’s animal and plant species. 

Our retreat center is located just outside Puerto Jiménez, a historic gold mining and logging community, and one of two major gateways to the the awe-inspiring, 425sq km Corcovado National Park – picture a biodiverse Eden home to some 140 species of mammals, 400 species of birds, 116 species of reptiles and amphibians, 40 species of fish, four species of sea turtles and more than 500 species of trees.   

Spend local days out exploring the peninsula’s spectacular beaches, snorkeling in calm coves, turtle-, dolphin- or whale-watching, kayaking through lush mangroves, before heading back to our gardens to, perhaps, swing lazily on a hammock while watching, through one eye, a squirrel monkey leaping to land on a branch overhead.  

The Food

At Nereus food isn’t just fuel, it’s a feature in your immersive experience with us. Just like we believe one size does not fit all in yoga practices, food is an individualized experience with the aim of supporting our students to feel their best. 

Our produce is seasonal and sourced locally from independent businesses, from the organic rice grown in-country to the mahi mahi caught just along the beach


Dagmar's teaching is . . .  intuitive, informed by decades of guiding others"

and ranges from strength building vinyasa flow to the quiet and restorative nature of yin practice . . . all, while being a beautiful expression of the sunshine within her.  A week long retreat with Dagmar includes a gorgeous venue, amazing healthy food and accompanying live music.  Her partner Daniel graces the room and lifts your spirit with the sweet sounds of the Hang instrument which he plays during yoga classes.  Thank you, Daniel!  And, Dagmar, thank you for your dedication to the yogic path, extraordinary depth of knowledge, warmth and sharing your wisdom and expert teaching skills for all levels.  Your light will remain a point of positivity on my journey.


Pamper yourself with true relaxation in stunning natural surroundings. You will experience the tranquil atmosphere of Nereus retreats upon arrival. Complementary activities will support you to reconnect with your body and soul.

This retreat is designed to take you deeper into your practice as we move into stillness, become more aware, more sensitive, and more receptive to the beauty in our lives.

Daily Activities

Each morning, enjoy a dynamic vinyasa flow practice with Dagmar. In the evenings, enjoy Daniel playing the Hang instrument live, while practicing a slow flow or yin with Dagmar. The yoga will help you to surrender and relax deeper into your breath and body. You will flow effortlessly through your practice.

The practices are open to all levels. Meditation and Pranayama are introduced and deepened as well.

We invite you to a 'Food As Medicine' nutrition workshop with our host Jen Millar, as well as a sunset kayak excursion.

Extra activities like massages, beauty treatments, professionally led walks and excursions, horse back riding, and more can be arranged for you on-site at additional cost.

We recommend adding a couple extra days to explore the famous Corcovado National Park and will be happy to recommend good guides.


Nutrition Workshop with Jen Millar

What does ‘food as medicine’ really mean and how can I apply this in my daily life?

These days we hear the term ‘food as medicine’ in reference to health supportive eating, but what does that really mean? Whether we credit this concept to Hippocrates, the ancient Ayurvedic medical texts, or modern day Functional Medicine, it is the belief that diet is integral in supporting health as well as preventing and curing disease.

After this workshop you will be able to:

  • Describe what ‘food as medicine’ means.
  • Understand how to apply this concept to support your own health through diet.
  • Prepare some simple recipes to add flavor-packed, nutrient-dense foods to your plate.

The workshop includes a cooking demonstration and recipe PDFs to take home.

By air… 

Sansa Airlines

www.flysansa.com for details and to make a reservation.

Once you check in at the Domestic Terminal for Juan Santa María airport (SJO), within two hours you could be standing on our beach. Sansa is the principal national airline,  flying to 13 locations in Costa Rica. They operate Cessna Caravan airplanes with capacity up to fifteen passengers. 

The flight to Puerto Jiménez (PJM) is only 40 minutes long and will take you over the mountains in the central valley and along the Pacific coast, cruising over the “Whale’s Tail” near Uvita, the Sierpe River Delta and the Gulfo Dulce. It’s a wonderful opportunity for some jaw-dropping photos.

Once you land in Puerto Jiménez it’s a quick transfer of approximately 5 km to Nereus Retreats. 

Prices are on average $140 one way with Sansa. 


By road …

Shared taxi-van shuttles can be arranged and are about $450/one way. Capacity depends upon the driver's vehicle and how much luggage. We will help coordinate group transfers.

Waze is the most commonly used navigational app in Costa Rica. Google Maps is also a reliable tool. Search for “Hotel Nereus, Puerto Jiménez”. The apps may offer you a variety of routes but our best advice is to take highway #27 (autopista) west, before heading south on #34 over Río Tarcoles, where you can stop and see crocodiles from the bridge, and then highway #2 before turning right onto road #245 to Puerto Jiménez. All the roads, until the last few kilometers are paved and in very good condition. The last 5 kilometers are on a flat, municipality-maintained dirt/gravel road. Overall the journey takes in the region of six hours, but it’s a wonderful opportunity to take in the Pacific coast, palm plantations, and jungle. You would have a particularly memorable experience if you chose to do the journey over a couple of days and stop off at the National Park of Manuel Antonio or hike to the Nauyaca Waterfalls.
