Boca La Caja is a surf spot located next to a large protruding rock and just off the Corredor Norte expressway. It's known for its fickle waves and tends to attract a decent crowd. If you're heading there, be prepared for a lively atmosphere with a mix of locals and surfers. It's important to be aware of localism in the area, so approach with respect.

The waves here can be a bit hit or miss. The optimal swell direction is from the south, but it also handles swells coming from the south-west. You can expect to ride waves that break over an uneven reef, with both left and right breaks available. Boca La Caja is best enjoyed at mid to high tide, and it works well with swell sizes around 3 feet (about 1 meter). This spot is geared towards expert surfers, so it's ideal if you’re looking for a challenge.

When it comes to wind conditions, a north-west wind is preferable. Just keep in mind that the crowd factor here can be quite high, so be prepared for some competition in the water. Make sure to check the conditions before you go, and enjoy your time surfing at Boca La Caja!
