Trip Overview
Originally introduced as part of the broader Tsimane program expansion, Agua Negra Lodge has evolved into one of Bolivia’s premier golden dorado operations. Designed for small groups of up to four anglers per week, the program offers exclusive access to a vast and remarkably diverse fishery while maintaining the intimate, remote feel that defines the Tsimane experience. Guests fish from a comfortable, well-appointed base camp and enjoy the same high level of guiding, wilderness immersion, and fishing opportunities Bolivia has become known for.

Lodging Details
Agua Negra features four single occupancy lodge rooms that include comfortable beds (including all linens and bedding), generator-supplied electricity, and a private shower and bath. Even in these remote locations, guests will have full-electric power via generators. The large dining and common area are spacious, well-lit, and very comfortable.

Food and Beverages
Each night guests will enjoy delicious international cuisine, fresh meats and vegetables, and great Argentine wines. Breakfast is cooked to order each morning, and lunches are packed for each day on the water and served streamside each afternoon. All beer, wine, and liquor are included in your lodge package. Overall, the food at the lodge is delicious, and the lodge staff will be happy to accommodate any special requests and dietary requirements.

Typical Length of Stay
The standard package for the Tsimane program is seven (7) nights / six (6) days of fishing with one night on each end typically spent in Santa Cruz (included in the package). Contact Yellow Dog for specific trip dates and availability.

Non-Angling Activities and Options
Tsimane operates in a remote, fishing-focused destination. It is not the ideal location for non-anglers and is best suited to those who are there to fish. That said, the wildlife, birds, and butterflies are amazing, and sure to impress even the most hard-core angler.

Internet / Communications
Satellite Wi-Fi is available at both of Tsimane’s lodge locations. There is also a satellite phone on site for emergency use.

How To Get There
Guests will fly into the Bolivian city of Santa Cruz (VVI) on an international flight. Upon arrival in Santa Cruz, guests will be met by a member of the Tsimane team at the airport and then transferred to a 5-Star hotel for their first night in the country. There, guests will settle into their room and enjoy the amenities of one of the best hotels in Bolivia. The Tsimane team member will further explain the details of the trip, and the following morning guests will take a charter flight to the Ormoromo Community landing strip – a flight of approximately 1 hour. Upon arrival at the lodge’s jungle airstrip, anglers will be met by the guides and transferred by boat to the camp.

Arrival and Departure Details / Times
You will want to arrive in Santa Cruz (VVI) the day or evening before your flight into camp. You will always want to overnight that first night in the city and depart for the lodge the following morning.

Documents Required
Passports valid for at least six months from the date of entry into Bolivia are required to enter and depart Bolivia. As of Dec. 1, 2025, U.S. citizens do NOT require a Visa. A Yellow Fever vaccination certificate will be required for entry into Bolivia.

General Information
The Secure River offers crystal clear waters wedged between lush jungle mountains. This section of the river is accessed using handmade wooden dugout canoes (coambas) outfitted with push poles and small engines. The middle sector of the Secure River runs from Asunta Lodge to the confluence of the Agua Negra River. It is typical to fish this section by wading downstream and using the dugout canoes to move from run to run. This middle stretch is shallow and open, filled with a subsurface structure that provides perfect ambush points for large numbers of trophy dorado. The Agua Negra River is an important tributary of the Secure River and is the newest addition to the Tsimane fishery. This river is roughly half the size of the Secure and is home to some seriously large dorado and good numbers of Pacú. There is also the option to do an overnight camp at the intimate headwaters of the Agua Negra river, which allows you to pursue fish that don’t get fished as often.

Boats and Equipment
In order to move around and fish the shallow area waters, Tsimane has designed fishing boats based on the simple and proven designs of the area canoes favored by the natives. Outfitted with small outboard engines, these wooden, canoe-style, 28’ boats are comfortable and extremely practical for fishing the local waters. Typically, two boatmen will pole the craft up and downriver, utilizing a small motor for running in deeper sections. There are two seats in the canoes for guests and plenty of room for gear and equipment. Although some fishing can be done from the boats in slower, deeper waters, most fishing is done while wading in the river or fishing from the banks and gravel bars. It is recommended that anglers bring all of their own equipment to the lodge, including backup rods and fly lines, and felt-soled wading boots outfitted with carbide-tipped studs. Flies are available for sale in limited quantities in most camps.
