And I'd say you were sticking way too close to conventional. Grab a bus from ACA to Huatulco. Hire a cab - cheap - for a run to Barra de la Cruz for great surfing in a much earthier location than Puerto Escondido. The folks from La Crema Bar in Huatulco have a new place to rent rooms there; it's a tiny community with spectacular surfing. Heading back, bus it all the way back to Pochutla. Something tells me you're not the kind to grab a rural transportation truck, so bargain for another cab to get from Pochutla to Zipolite-Mazunte-San Augustinillo-La Ventanilla and just stop at whichever makes your heart go pitter-patter. The Italian food in Zipolite and Mazunte will amaze you. And if none of these little communities make your heart dance, then you have no heart.
And next trip, maybe I'll recommend some even MORE out-of-the-way spots.
