Marina Lago serves as the lakeside access point for Lodge Tepuhueico on the shores of Lago Tepuhueico, a remote lake situated in the west-central interior of Isla Grande de Chiloé, within the commune of Chonchi in the Los Lagos Region.

The lake spans roughly 14 square kilometers, surrounded by dense temperate rainforest that shelters endangered species such as the zorro chilote and the monito del monte.

The marina provides a gateway to nature-based activities on and around the lake, including kayaking, wildlife observation, and hiking through old-growth evergreen forest.

The broader area is recognized as one of the largest private reserves of temperate rainforest in the world and functions as a hub for conservation, scientific research, and low-impact ecotourism.
