2. Ethel M Chocolate Factory
Not only is this experience free, but it is a unique and rare activity that is not easy to come by. The Ethel M Chocolate factory allows self-guided tours for free, but you have to pay some additional charges if you would like to participate in the chocolate tasting. Regardless, you get to see first-hand how some of the tasty confectioneries are made; there are select free samples to enjoy. Lastly, you can enjoy a walk in their extensive cactus botanical garden for free.
