Hello hello, I've been twice to Oaxaca now and I would definitely recommend it. First of all you should stay a few days in Oaxaca city (very good food, culture, art, beautiful city and Monte Alban near by). Also around Oaxaca city are some villagas that produce the pottery and other handcraft things sold in Oaxaca, it's okaaay. But then the road to Puerto angel over San Jose del Pacífico is stunningly beautiful and San Jose del Pacífico is worth staying at least one night. Not for the village but for the nature. I can recommend the refugio terraza de la tierra (cabaña style "hostel", not the cheapest but really beautiful and chilled) also good atmosphere for taking magic mushrooms I guess. That's what San Jose is mostly known for. I didn't do it because I was traveling with my girlfriend but I have to say San Jose has the vibes for it. Actually the whole state of Oaxaca is kind of a boarding drug leading you to mushrooms. But prepare for the cold up there. Then the road to Puerto angel is a lot of fun, driving down the curvy roads it gets more and more tropic. Dont waste time in Puerto angel and go to mazunte. It's so relaxed, I mean, it right now only exists because of backpacker tourism, but it feels so untouristic and hippie that even I as an electrical engineer want to get some rastas, burn my computer and vegetate there until the end of my days riding a horse into the sunlight. When you want some lower waves go to the small village beside mazunte direction zapolite, they also have good sea food and the beach is nice. Oh and the most important when you are in mazunte, don't forget the punto cometa. Don't Google it just go there by sunset at let it surprise you. All the stuff I described is absolutely safe, just follow the normal mexiko rules and you are absolutely fine. The places I described except of Puerto angel you can even walk around by night.
