| EL YUNQUE NATIONAL FOREST with a private Certified Interpretive Tour Guide |
| Due to the number of people visiting El Yunque National Forest during the Holy Week/Weekend (Wednesday through Sunday, including Good Friday and Easter) and the month of July (we have four holidays, July 4, July 17, July 25, and July 27), we DO NOT OFFER tours to El Yunque other than the Night Hike and/or Taíno Ceremony. Access to the Forest is limited and we cannot guarantee the quality on those days. |

| Bioluminiscense has been observed in El Yunque during our night hikes in terrestrial animals (fireflies, click beetles, glow worms) and fungi. All new information gathered on each hike is shared with scientists from the Forest or universities. Be part of this effort an join us during moonless nights. |
| There are seven confirmed bioluminescent species of macro-fungi in El Yunque National Forest. These fungi are capable of glowing in the dark. Join us in the search of these unique mushrooms. We will also see other forms of bioluminescense, plus the non-bioluminescent coquí. Special weather conditions should take place to see the glow-in-the-dark mushrooms. Due to the nature of this private nature walk on a fragile habitat, groups are limited to a maximum of 4 to 6 participants. Available only on moonless nights, three times per month. |
| Celebrating sixteen years in the East region! |
