He wahi maikaʻi ʻo El Cielo no nā haʻuki koʻikoʻi, ʻoiai ma loko o kona wahi he mau mauna a me nā kahawai e hāʻawi i nā hana ʻoi loa e like me ka rappelling, kayak, paikikala mauna, caving, cascading a, ʻoiaʻiʻo, keʻaʻa ʻāina.
He wahi kūlohelohe ʻo El Cielo i pale ʻia mai ka makahiki 1995 e ke aupuni ʻo Tamaulipas ma muli o ka nui o nā pua a me nā holoholona. Aia ia ma ka hema komohana o ka mokuʻāina ma ka Sierra Madre oriental a me nā kaona ʻo Gómez Farías, Acampo, Llera a me Juamave. ʻO ka palena e pili ana i ka akau e ka muliwai Guayalejo, i ka hema e ke kulanakauhale o Acampo, i ka hikina e kahi kiʻekiʻe o 200 m ma luna o ka ʻilikai, me ka muliwai ʻo Sabinas a me kāna kumu.
I ka makahiki 1986, ma o kāna papahana Man and the Biosphere, ua hāʻawi ka UN iā ia i ke poʻo inoa o Reserve of Humanity; ʻO kāna kumu i kēia manawa e mālama i nā ʻano holoholona a me nā mea kanu e noho ana ma laila, a e hōʻoia hoʻi i ka ulu mau a me ka ulu kūlohelohe, a me kahi hoʻomohala kaulike i waena o nā kaiāulu e noho nei i loko o nā wahi kūlohelohe.
Ma kahi o 50 mau makahiki i hala aku nei, he hale kani kani ʻo El Cielo kahi i kua ʻia nā pine a me nā ʻoka, akā i kēia lā ʻo ka mea wale nō i koe o nā kino o nā mīkini ʻino i hoʻohana ʻia e hoʻoneʻe i nā kumu lāʻau.
ʻO kekahi o nā hana a nā poʻe noho ma El Cielo e mālama ai, ʻo ia ka ecotourism, kahi i hoʻonui i ka ulu ʻana i nā makahiki ʻehā i hala aku nei, me ka hoʻohui i nā holoholona a me nā mahiʻai. Ma muli o ke kokoke, ʻo ka ʻāpana luna o ka biosfir, ke kaiāulu o Gómez Farías, kahi mea i pōmaikaʻi loa i nā ecotourists, no ka mea hāʻawi ʻia nā lawelawe halihali a me kahi hoʻokipa ma laila no ka poʻe e makemake e mākaʻikaʻi i ka wahi.
He wahi maikaʻi ʻo El Cielo no nā haʻuki koʻikoʻi, ʻoiai ma loko o kona wahi he mau mauna a me nā kahawai e hāʻawi i nā hana ʻoi loa e like me ka rappelling, kayak, paikikala mauna, caving, cascading a, ʻoiaʻiʻo, keʻaʻa ʻāina.
