Also known as SPI, the island is the perfect destination to progress your kiteboarding. The Island has flat water on the Laguna side, and waves on the Gulf side. The 'Flats' as they are known, are shallow enough to stand on your feet up to a 1/2 mile out in the water. With the ability to stand up you can easily regroup your composure (and gear) all without drifting downwind. The shallow water also prevents waves from building up, one less element to contend with while learning.
When you are ready to take on some waves, the Gulf has miles of beach for wave riding or a downwinder.
SPI is easy and affordable destination to travel to. Most US airports provide direct flights to Harligen or Brownsville TX.
