Focusing right now on pages 364-474, since I’m going to Zihuatanejo next month. I can see this book getting a lot of future use as well.
Putting the book down now, post-Mexico. The Zihua section was not particularly good. Short on information and maps.
As for my own trip, stayed at Hotel Catalina in Playa de la Ropa in Zihua for a week. Hiked to Playa Manzanillo for snorkelling (also accessible by $40 boat ride) a couple of times, and took a boat to Isla Ixtapa for snorkeling on Playa Carey (VERY recommended). Sunset from the bar at Brisas Ixtapa one night, but that was the extent of Ixtapa for me. The rest was pure Zihua, some time spent in El Centro, walking along the beach from Playa Madera to the center of town, 2 pajaros verdes (parrots) lurking in the window of a bar along the walk. Walked the opposite direction to Playa Las Gatas for more snorkeling, beer and fish tacos. Car not necessary or very useful, although it did take me on an extended dirt road tour to Barra di Potosi, where I was the only one on the beach. Zihua a gorgeous bay, it would have been great to discover it years ago before the jetskis and parasailing invaded. Hay muchos americanos tambien. Es la vida.
