Sedona Philosophy Experience (SPEX) is an Arizona Benefit Corporation based in beautiful Sedona, Arizona. SPEX 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 a variety of philosopher-led hikes among the majestic red rocks of Sedona, in which participants are encouraged to ponder, discuss, and compare opinions on life’s big questions.

SPEX is a socially responsible company that exists to enhance environmental and philosophical awareness, this purpose forms the foundation of every SPEX initiative.
