Its three largest events were swells from southern storms moving south to north, on 19 June 2006, 4 July 2014 and 2 May 2015. The speedboats are often called ferries, but Moon Travel Guides says they are designed for speed rather than stability.

  • Plan for 2 to 2.5 hours and put your phone away for the whole crossing. Ferryscanner lists averages of 2h 12min to Isabela and 2h 9min to San Cristóbal.
