Most of the taxi drivers know where La Paloma is. The airport transportation service from the Manzanillo airport takes about 25 minutes. Taxi tickets are purchased inside the airport terminal, ask what the fare will be to Melaque/San Patricio. You should expect to pay around $600 pesos per couple. A return fare to the airport from La Paloma is $400 pesos per cabload (up to 4 people). DO NOT negotiate a return taxi ride to the airport with your airport taxi guy, as they are not allowed to pick up here in town.
For those arriving at the Melaque bus depot, it is a three minute taxi trip to La Paloma. Cost is generally about $50 pesos
