From late June through early October, the ocean off Ecuador's Pacific coast is the breeding area for hundreds of humpback whales, which migrate there from the icy waters around Antarctica. Boat tours out of Salinas, Puerto López, and other ports offer an opportunity to observe those amazing creatures, the largest of which are 15m (50-ft.) long and can weigh as much as 50 tons. Whale-watching tours may include a stop at Isla de la Plata, an offshore island where thousands of seabirds nest.
Exploramar Diving (tel. 02/2563-905; www.exploradiving.com), in Puerto López, offers whale-watching tours on one of two boats.
Guacamayo Bahía Tours (tel. 05/2961-412; www.riomuchacho.com) runs inexpensive whale-watching tours out of Bahía de Caráquez.
Guayatur (tel. 04/2322-442; www.guayatur.com), a Guayaquil-based tour operator, organizes whale-watching tours that head to sea from Salinas.
Machalilla Tours (tel. 05/2300-234 or 09/6109-185; machalillatours@yahoo.com) is my favorite operator in Puerto López; they offer whale-watching excursions throughout the whale-watching season.
