Caño Negro National Wildlife Refuge

Por: BEEN THERE COSTA RICA | Publicado: 11/12/2010 15:58 |

Caño Negro is quite off the beaten path, but worth the effort. Most visits start out at Los Chiles where you board a boat and glide up the Río Frío through canyons of green towards the everglade like Lago Caño Negro. Migration plays a big role in the population of the waterways; you may see a bull shark's fin slice the surface; this area is the end of their annual trip up the Río Nicaragua from the sea, but most people come to spot migratory birds.

During the green (rainy) season from May to October, water from the mountains is plentiful and the Río Frío overflows its banks to form Lago Caño Negro positioned smack in the middle of the flyway for migrant North and South American birds. Millions of birds arrive here to winter over during the dry season beginning in December. The water level falls continuously for the next three to four months until all that is left is the main channel of the Río Frío and the migrants depart.

Among the many birds found in Caño Negro are: glossy Ibis, black-necked stilt, neotropical cormorants, American anhinga, northern jacana, American widgeon, wood stork, white Ibis, black-bellied tree duck, northern shoveler, snail kite, green backed heron, roseate spoonbill, and blue-winged teal. This is one of the best places to see the Nicaraguan grackle, whose only Costa Rican habitat is Caño Negro and other marshy areas just south of Lake Nicaragua.

The Río Frío has good fishing for snook, guapote, alligator gar, drum, and huge tarpon (fish stories claim up to 100 kg or 220 lbs). Fishing is allowed in the reserve from July 1 to March 31, license $US 30 from the ranger station in Caño Negro village. There are no established high profile fishing guide outfits currently operating, but if you are willing to round up a boat and provide most of your own tackle, Caño Negro is a well kept fishing secret.

In the region:
East of Los Chiles, the Río Medio Queso spreads into a shallow wetlands when rainfall is plentiful. The region near the border is officially protected by the Corredor Fronterízo National Wildlife Refuge, but the whole area is excellent for wildlife viewing.

Caño Negro isn't particularly near anything. When we visited, we embarked on a small boat at Los Chiles with our bicycles stacked to one side spent the cay on the river and lake then disembarked at Caño Negro village, where we continued west and south. If you are traveling by bus, your only option is back towards La Fortuna Arenal and San José. If you are driving, there is no bridge over the Río Frío at Los Chiles, you have to turn west off the main road about 6 miles (10 km) south to reach the nearest bridge at San Emilio to drive to Caño Negro village and on to Upala (4WD recommended year round and required in the rainy season).

Travel & Site Guide to Birds of Costa Rica With Side Trips to PanamaTravel & Site Guide to Birds of Costa Rica With Side Trips to Panama
by Aaron D. Sekerak, Aaron D. Sekerak, Eussa Ginger, Elissa Conger (Illustrator), Paperback, 256 pages, Publisher: Lone Pine Publishing, (1996), ISBN: 1551050846

This book is exactly what it says, a guide to birding sites. It is not a field guide with color illustrations etc. That said, it's a useful tool for planning a trip or getting more information about regions you are seeing on an organized tour. Includes some interesting back doors, and info on who to talk to in specific areas about seeing birds. If someone said "I would give $1000 to see aCalliphlox bryantae" you would have to look the common name up in a bird book first, then use the Travel and Site guide to locate a likely locale.

From San José there are several routes to the northern lowlands. The main route follows the Pan American Highway west out of San José towards Naranjo (and San Ramón, but don't go all the way there), after ~32 km turn right (north) on 141 to Naranjo followed by a 22 km climb to Zarcero that pays off when you get out and stretch your legs in the amazing topiary garden surrounding the whitewashed church (on your right in the center of town, you can't miss it). Continue on 141 another 20 km to Quesada (known as San Carlos to all but map makers), then 8 km to Florencia where you turn right (north) on 35 which takes you the final 84 km to Los Chiles. (No 4WD required)
To get to the ranger station at Caño Negro village you have to turn west off of 35 onto a dirt road about 10 km before (south of) Los Chiles (there is no bridge at Los Chiles) to cross the Río Frío at San Emilio. You can continue from Caño Negro village to Colonia Puntarenas (4WD recommended year round and required in the rainy season) where you can catch the paved road to Upala.
Detailed roadmaps are available in acrobat pdf formator printed on waterproof tear proof plastic.
