our Retreat Center

Rainforest meets ocean at our private, boutique yoga and wellness destination. Immersed in nature steps from the beach at Golfo Dulce (sweet gulf) and a boat ride from Corcovado National Park, our location supports rebalancing the nervous system as we come into harmony with our circadian rhythms, sisterhood and the beautiful simplicity of jungle life.

The bio-diversity found on the Osa peninsula is unsurpassed. Corcovado National Park encompasses the only remaining old growth wet forests on the Pacific Coast of Central America, and 13 major ecosystems where there is a good chance of spotting some of Costa Rica’s shyest and most endangered inhabitants: Tapirs, Jaguars, Scarlet Macaws, Harpy Eagles, Red-backed squirrel monkeys and White-lipped Peccaries.

  • This was a totally immersive yoga retreat. The thought that went into the planning of the five elements was not only present in our practices, but they transcended into our excursions. When it was time to return home, I could feel the family we became. I leave liberated with a much deeper self-awareness of why I’m fearful. I am forever grateful for this incredible mind & spirit changing experience.

    - Gretchen Delameter “UNTAMED” 2025

  • The retreat offered an ideal balance of nourishing cuisine, relaxation, adventure, customized massages and self-discovery. Whether you’re looking to deepen your yoga practice, reconnect with nature, or simply unwind, this retreat provided the perfect escape.

    - Kim Mahoney “UNTAMED” 2025

  • "Simply magical! Amanda curated an amazing experience… each day having a theme that celebrated the Greek Goddesses! Amanda has a gift of cultivating connections while creating space for others to co-create with her! She’s truly a special being and I highly recommend any event/retreat offerings from Santosha! Thank you for such an incredible experience."

    Sat Nam ~ Leslie, IMMERSE Greece 2023

  • I went on my first yoga retreat to Costa Rica. I barely knew anyone who was going, but Amanda and Julie made sure I was welcome and comfortable. I left with 15 new friends and the memories of a lifetime. Yoga twice a day was extremely nice for me, even though I'm new to yoga. The excursions that were offered were private for the group and absolutely amazing. Jennifer and Amanda where their the entire time to make everything seem effortless and simple. If you're looking for a retreat to recharge, refill, and grow...this is the group to do it.
