The Pacific coast of Mexico is a playground for active travelers. Warm waves and sunny skies attract the beach crowd with watersports, while volcanoes, mountains and jungles appeal to hikers, naturalists and the culturally curious. Visit a pearl farm in San Carlos, ride a train through Copper Canyon, go crocodile hunting on La Tovara River, surf the big waves at Playa Las Islitas, or visit the village of Ajejic, where DH Lawrence once got inspiration.
