No matter where you are staying, boat trips are available for a surfing or fishing trip.  If you are staying in Hacienda Iguana, boats can be arranged to pick you up just off the beach at Colorado, but be aware that you will need to swim/paddle to the boat as they cannot launch from the beach.  Driving to Gigante Bay and launching directly from the beach is another option.  If you are staying in the Popoyo/Guasacate area, boats can also be arranged to pick you up in front of wherever you are staying, or you can drive to Astillero (20 minutes drive north).  Astillero is a fishing village inside a protected bay where the boat can launch easily from shore.
