Connecting people to the aquatic world, one breath at a time.

Reduce stress

Improve safety

Connect with nature

The mission of One Breath Adventures is to help people develop confidence, awareness, and environmental connection through breathwork, freediving, and unforgettable experiences in the water.

Spending time in water increases dopamine, serotonin, and oxytocin while also reducing cortisol. That means less stress, a boost in happiness and creativity, and improved emotional health.

Diving on one breath develops physiological awareness and creates opportunities for more ethical wildlife interactions and safe aquatic recreation.

We run courses and trainings in Colorado, and guided coastal trips for students to apply what they’ve learned. Whether you simply want to improve snorkeling skills or you want to dive deep into your physical abilities, the journey starts here.
