Arrange fishing trips through travel agencies or through the Cooperativa de Pescadores (Fishing Cooperative), on the malecón north of the Río Cuale, next door to the Rosita Hotel (tel. 322/222-1202 or 322/224-7886). Fishing charters cost $250 to $400 a day for four to eight people; price varies with the size of the boat. Although the posted price at the fishing cooperative is the same as you'll find through travel agencies, you may be able to negotiate a lower price at the cooperative, which does not accept credit cards. It's open Monday through Saturday from 7am to 10pm, but make arrangements a day ahead. You can also arrange fishing trips at the Marina Vallarta docks, or by calling Fishing with Carolina (tel. 322/224-7250; cell 044-322/292-2953; fishingwithcarolina@hotmail.com), which uses a 30-foot Uniflite sportsfisher, fully equipped with an English-speaking crew. Fishing trips cost $350 for up to six people and include equipment and bait, but drinks, snacks, and lunch are optional, at $10 per person. If you mention Frommer's when you make your reservation, they'll offer a free lunch with your booking.
