Sena

Sena (Río Sena) is a small historic settlement on the left bank of the Madre de Dios River in Bolivia's Pando Department, within Madre de Dios Province in the country's far-northern Amazon. It is one of the oldest barracas (rubber estates) in the region, dating to the height of the Amazon rubber boom toward the end of the 19th century, and its surviving warehouses and workers' housing make it a tangible relic of that era.

During the rubber boom — which in the Bolivian Amazon ran roughly from the 1890s into the early 20th century and continued in waves until around 1940 — the Madre de Dios basin was prized for its high-quality latex. Frontiersmen from Santa Cruz, who had established cattle ranches in the Beni, moved up the Madre de Dios, Mamoré and Iténez rivers to control the forests, and stations like Sena shipped rubber down to Brazil and beyond. The human cost was severe, falling heavily on the region's indigenous peoples. Today Sena is a quiet riverside community that preserves this layered history.

The climate is hot and humid tropical year-round. The drier May-to-September season is the easiest time for river and road travel; the November–March rains raise the river and make overland access difficult.

By Plane

There is no airport at Sena. The practical air gateways are Riberalta in neighbouring Beni (nearest, reached by river and road) and the distant Captain Aníbal Arab Airport (IATA: CIJ) in Cobija.

By Train

By Car / Road

Sena lies on the Madre de Dios River in eastern Pando, far from Cobija over long, largely unpaved Amazon roads. Access is generally by river boat along the Madre de Dios and by road from the Riberalta side; overland travel is weather-dependent and often difficult in the rainy season.

Sena is a small riverside settlement best explored on foot. Movement to other communities is mainly by boat on the Madre de Dios River, supplemented by informal road transport. There is no formal public transport.

• Historic rubber-era barraca — the surviving warehouses and workers' housing from the late-19th-century rubber boom, the settlement's defining feature.

• Madre de Dios River — the great Amazon river on which Sena sits, central to its past and present.

• Surrounding rainforest — classic Amazon forest along the riverbanks, rich in birds and wildlife.

• Explore the rubber-boom heritage — walking among the old barraca buildings is the main reason to come.

• River trips on the Madre de Dios — fishing, birdwatching and wildlife-watching by boat.

• Forest walks — the riverside rainforest, with local guidance.

Food is basic and river-based: freshwater fish from the Madre de Dios, grilled or fried, with rice, yuca and plantain. Simple home-style cooking is the norm; do not expect restaurants or varied menus.

Soft drinks, beer, coffee and fresh fruit juices are available where shops exist. Drink only bottled or treated water.

There is essentially no formal lodging at Sena; this is a small community rather than a place geared to visitors. Travellers normally base themselves in Riberalta and visit Sena by river or as part of a wider Amazon trip.

There is no shopping to speak of beyond small shops covering daily needs. As across the region, Brazil nuts (castaña) are the characteristic local product; wider purchases are made in Riberalta.

• Riberalta — the nearest major Amazon town (in Beni), with an airport and services.
• Puerto Gonzalo Moreno — provincial capital of Madre de Dios, on the same river system.
• San Lorenzo — the neighbouring Madre de Dios municipality, with its riverside lagoons.
• Cobija — the distant departmental capital in western Pando.
