The Experience

Before You Go

Wear closed-toe water shoes

Sturdy, grippy shoes that drain well are essential for wet rocks and river crossings—no flip-flops or crocs.

Bring a dry change of clothes

You will get soaked; a towel and dry shoes for the return make the long day much more comfortable.

Respect the bio bay

Avoid sunscreen, insect repellent, and soaps before the kayak portion—contaminants damage dinoflagellates.

Know the weight limits

Maximum individual weight is 240 lbs and combined kayak limit 425 lbs; weight checks are enforced for safety.

Local Knowledge

Hidden Gems

  • Luquillo kiosks for local fritters and pinchos after the tour
  • A quieter side pool in El Yunque where guides often stop for photos and a quick swim

Wildlife

  • Puerto Rican parrot (heard, seldom seen)
  • Coquí frog

Conservation Note

Laguna Grande’s dinoflagellates are sensitive to pollution and light; guides enforce no-soap rules and limit artificial light to protect the ecosystem.

El Yunque’s ridges are remnants of volcanic and granitic activity and the area was used by Taíno communities long before European contact; the forest later became protected as a national forest in the 20th century.
