one of the world's last fly fishing frontiers


A crystal clear river surrounded by pristine jungle, the Rio Casare is truly an adventure fly fishing destination. The freestone river flows from the high Andes through a remote indigenous territory to form a drainage that eventually makes its way to the Amazon River. This territory looks much like it did thousands of years ago. With its majestic main stem and the various virgin creeks and streams teeming with aggressive exotic species, the Rio Casare is a true fly angler’s paradise.

Bolivia is one of the world’s last fly fishing frontiers, and we offer a series of hosted trips to this unspoiled area to catch massive golden dorado (Salminus brasiliensis) as well as exotics like yatorana (same genus as Costa Rica’s machaca), tabarana (Salminuds hilarii), pacu (Piaractus brachypomus), surubi (Pseudoplatystoma sp.), and more. The river runs low and clear, navigable only by small reinforced dugout canoe and fly fishing involves moderate wading. Wildlife like tapir, jaguar, and neotropical birds abound, and the lush forest framing the river will deliver a symphony of animal sounds as you sight cast at various exotic species.


But why the Rio Casare? This river has been left nearly untouched due to its impossible remoteness. Besides world class fly fishing this trip involves interaction with the local indigenous community to experience a part of their culture, customs, and connection with the surrounding forest.


Access to the river has also been kept much lower then other similar rivers in Bolivia (less then 100 anglers per season), ensuring both the conservation of the incredible wilderness one encounters but also to the extremely high quality fly fishing. Base camp is also moved from time-to-time to different parts of the river, which provides anglers the opportunity to explore pristine new waters and cast at fish unaccustomed to flies.


The region has been developed exclusively together with the Tsimane indigenous communities inhabiting areas adjacent to the river. The goal is to ensure that catch-and-release fly fishing expeditions not only helps provide a sustainable source of livelihood to these communities but also provides a means to preserve their unique language, culture, and skills.


Besides being accompanied by a guide from our local partner, we team up with local Tsimane guides for a truly authentic adventure. These native people have generations of jungle knowledge and a keen eye for spotting fish. The Tsimane guides and other staff are very hard working and are always looking out for the anglers’ safety. Their good humor is shown in their laughter and constant smiles. Although they may seem small, they are incredibly tough and strong, and have no problem poling and portaging anglers upriver. Watching them interact with their jungle environment is an experience all it’s own. Throughout your journey, you will see them utilize parts from many different jungle plants for various applied uses. Observing them closely and fishing side-by-side is a cross cultural learning experience that will stay with you forever. This is a true angling adventure of the lifetime, and we invite you to join our hosted trips to the remote Rio Casare.
