Sedona Philosophy Experience was conceived by four university professors who had the crazy idea to bring their love of philosophy and nature to the hiking public in a completely new way. SPEX offers philosopher-led hikes, tours, and retreats among the majestic red rocks of Sedona. Participants are encouraged to discuss and compare opinions on life’s big questions. We are not here to tell you what to think but to stimulate conversation and thought.  No experience is necessary--just a natural curiosity about the wonders of life.


Some of Life's Big Questions
What is the meaning of life?
What is knowledge and truth?
What is good and moral?
What is happiness?
What should I do with my life?
What should my relationship with nature be like?

Philosophy Hikes

Exercise the mind and body, while enjoying nature

The Philosophy Hike is a 2 1/2-hour excursion, into the stunning red rocks of Sedona along the banks of Oak Creek, to engage in a philosophical dialogue about everything from humanity's place in nature to the meaning of life. These hikes are as invigorating as they are inspirational. And though you may leave the red rocks behind, you can take the inspiration and insight wherever you go.



Custom Retreats

A weekend vacation to engage the body, mind, and spirit

Custom retreats are an ideal getaway that actively engages and restores the body, mind, and spirit. These unique programs are focused on various areas of meaningful philosophical inquiry and quiet contemplation, set against the backdrop of Sedona's natural beauty. They are customized to address specific topics and may incorporate meditation and yoga along with inspirational intellectual inquiry.
