The town itself is not terribly alluring, and it can be a hot, still place full of traffic, but at night it cools down and comes alive. The Parque Central area fills with strolling families taking their kids to the well-lit play areas, and a row of food kiosks sells food and fruit shakes at good prices.
There are many sights that make Chinandega a great place to come:
Large churches in town
Great park in the middle of town
Friendly, real people
