How to Get There: The Rocio del Mar is located at the Marina Fonatur in Puerto Penasco, Mexico. Marina Fonatur is approximately a 4-hour drive from Phoenix, Arizona.

Participants should ensure that their flights arrive in Phoenix no later than 11am on Sept. 12 in order to catch the shuttle, which departs at 1pm (details below.) The boat will return to port on September 19 where participants should be ready to disembark the boat at 7am via the same shuttle. Participants should book departing flights at 2pm or later out of Phoenix (PHX). Participants are responsible for booking flights their own flights out of Phoenix.

This shuttle service has 15 passenger vans that haul trailers for dive gear. The cost for the shuttle is around $150 per person (as of sept 2023), payable directly to Head Out to Rocky Point. Payment will be made prior to the trip. If you require this service, please indicate this on your Rocio del Mar passenger forms, which you will be prompted to complete a few months before the trip.
