A number of San Blas [1] captains take visitors on less extensive, but nevertheless potentially rewarding, wildlife-viewing excursions November–April. Sightings might include humpback, gray, and sperm whales, dolphins, seals, sea lions, turtles, manta rays, and flocks of birds, including gulls, frigate birds, cormorants, boobies, terns, and much more.
Contact either Pato Murillo (tel. 323/285-1281) or Santos Villafuente (at the Hotel Brisas del Mar, tel. 323/285-0870, local cell 044-311/109-1993) or super- experienced English-speaking Tony Aguayo at home (tel. 323/285-0364) or at his “office,” the little palapa to the left of the small floating boat dock at the El Pozo estuary end of Juárez. A typical five-hour excursion runs about $150 for up to six passengers.
