Most of the Jalisco coast, between Manzanillo and Puerto Vallarta, has been dubbed the Costalegre (the “happy coast”; wcostalegre.com), the wildest, most undeveloped stretch of Mexico’s Pacific shore. Beyond the low-key resorts of Melaque and Barra de Navidad, Hwy-200 snakes north for around 225km past lonely beaches, small villages and vast swathes of jungle-smothered mountains. Sadly, since 2010, many of the most accessible beaches have been closed thanks to disputes with private landowners – check the latest in Barra de Navidad or Puerto Vallarta before heading out.
