Bonanza — Nicaragua
Bonanza exists because of gold. The town sits at 183 metres in the forested interior of Nicaragua's North Caribbean Coast region, and together with Siuna and Rosita it forms what Nicaraguans call the Triángulo Minero — the mining triangle — a district that has been worked industrially since the early twentieth century and is still producing.
San Pedro Airport was built for that industry. It was, in the words of the historical record, essential to establishing gold mining operations in the 1940s and 1950s, at a time when there was no usable road into this part of the country at all. That is still substantially the case.
Airstrip at 183 metres elevation. ICAO: MNBZ. Coordinates: 14°02′10″N, 84°37′30″W. Operated by the Nicaraguan state. Daylight operations.
This is a short daylight-only strip, sized for the Cessna Caravan class that serves eastern Nicaragua.
What can be said with confidence is the operating character: this is an interior field surrounded by forest and low hills, at a meaningful elevation for the region, flown visually in daylight by the Cessna Caravan class that La Costeña and the charter operators use across eastern Nicaragua. Morning operations are the standard, and weather is the binding constraint.
Getting there
Bonanza Airport — Getting there
Bonanza is roughly fourteen hours from Managua by road, on a route that deteriorates significantly past Río Blanco and is unreliable in the wet season. The flight is about 70 minutes.
Locally, BZA connects to Puerto Cabezas — around 134 kilometres east, a short hop by air and a very long one by road — as well as to Rosita, Siuna and Bluefields.
For any operation into the reserve, for the mining companies, for medical evacuation and for the communities themselves, the airstrip is the practical link to the rest of Nicaragua.

Things to do near Bonanza
The commercial reason to fly here is mining. The other reason — and the one that will matter more over time — is that Bonanza is one of the principal access points for the Bosawás Biosphere Reserve.
Bosawás covers roughly two million hectares, was designated by UNESCO in 1997, and is the second largest rainforest in the Americas after the Amazon. It takes its name from three features it spans: the Bocay river, Saslaya mountain and the Waspük river. Together with the adjoining Honduran reserves it forms one of the largest contiguous protected forest blocks between Mexico and Colombia.
Cerro Saslaya National Park, inside the reserve, protects Nicaragua's highest non-volcanic peak and a cloud forest that holds jaguar, Baird's tapir, harpy eagle and quetzal. It is reached from the mining triangle with guides and permits, and it is genuinely expeditionary — this is not a place with trail infrastructure.
The reserve is the territory of the Mayangna (Sumu) and Miskito peoples, whose communities hold title to much of it and who manage access. Any visit is arranged through those community structures, not around them.
Industrial mining at Bonanza dates to the 1930s, and the company town that grew around the workings still shapes the settlement's layout.

When to fly
When to fly
Interior Caribbean slope: wet, and less seasonal than the Pacific side. The relatively drier and more reliable stretch is broadly February to April, with a secondary window around September and October; June to August is typically heaviest and the road becomes marginal.
The elevation and the surrounding terrain make BZA more weather-sensitive than the coastal strips. Cloud builds early here, and afternoon operations are frequently unworkable. Build the itinerary around morning departures.
