The Río Peulla flows through the Andean landscape near Villa Peulla in the Los Lagos Region, eventually emptying into Lago Todos los Santos. The river is characterized as a gentle mountain stream, making it accessible for paddlers of varying experience levels. It confluences with the Río Negro, and organized raft trips typically begin near this confluence, continuing downstream toward the village of Peulla. Along the way, multiple streams descend from Cerro Techado, adding to the visual character of the route.

Rafting on the Río Negro and Río Peulla combination is an available guided activity, with the journey starting in the Encanto Sector. Kayaking is also offered in the area, with routes that include paddling upstream to a sandy shore before returning downstream. The surrounding terrain features native Andean forests with coigüe and other old-growth trees, and the broader area includes the Los Cóndores and Techado mountain ranges.

Water levels on the Río Peulla drop noticeably toward the end of summer, which can affect paddling conditions. Activities are available year-round, subject to weather conditions. Early morning is noted as preferable for paddling on the adjacent Lago Todos los Santos, as waters tend to be calmer before approximately 9:30 AM, though this timing note applies specifically to the lake rather than the river itself.

Organized paddling activities in the area are based out of Villa Peulla, where guided trips and equipment are available through local operators. The difficulty of paddling excursions in this area is rated as moderate.
