Laguna de Amela is a calmer counterpoint to Tecomán's open Pacific beaches. The lagoon sits inland from the coast, surrounded by low vegetation and rural communities, and is most appealing if you like birds, still water, and quiet landscapes.
It is a simple nature stop rather than a developed attraction. Bring what you need, go in daylight, and treat it as a slow detour from the surf beaches rather than a full-day destination.
