san juan de nicaragua — greytown
Isolated village in the Río San Juan delta on Nicaragua's Caribbean coast, between Indio Maíz Reserve and the sea: tarpon and snook in the channels, lagoons and bar.
San Juan de Nicaragua, the former Greytown (San Juan del Norte), sits in the Río San Juan delta at the far southeast of Nicaragua, on the Río Indio. The village lies between the Río San Juan Wildlife Refuge and the Indio Maíz Biological Reserve, with 316,720 ha of forest. Tarpon enter through the bar and move through the delta arms, coastal lagoons and channels; fishing is done from a panga, with heavy artificial lures, jigs and natural bait. White snook and fat snook (calva) are at channel mouths and in the surf, and jacks appear at the bar. Upriver, guapote and machaca bite on small lures. It is expedition-style fishing, with little infrastructure and a lot of rain.
best season
Tarpon are in the delta all year. It rains heavily almost all year; the driest months, February to May, and September and October, tend to bring clearer water and calmer bar conditions.
Local rules: The Fisheries Law (Law 489, art. 82) bans industrial fishing on the Río San Juan and allows only sport and tourist fishing with the authorities' permit. INPESCA minimum sizes in inland waters: tarpon 120 cm, white snook 50 cm, fat snook 30 cm, guapote lagunero 25 cm. The Indio Maíz Biological Reserve and the Río San Juan Wildlife Refuge are MARENA areas: enter only with a guide and authorization. The river forms the border with Costa Rica: bring your passport. Release the tarpon. Confirm local rules.
- getting there
- There is no road to the village. From San Carlos, a boat goes downriver along the Río San Juan, passing El Castillo, on a long trip. Arrange transport and the return trip in advance.
- facilities
- Simple inns and few services. Local guides and boatmen take you to the delta and the bar; arrange everything beforehand, because there is no tackle shop.

tip
The San Juan bar has waves and shifting sandbanks: only head out with a local pilot and calm seas. Bring a rain jacket, spare lures and insect repellent.
