Parque Tantauco  is a privately owned park (owned by the current Chilean president and billionaire businessman Sebastián Piñera) open to the public (similar to Parque Pumalin) in Chiloe Island, Chile.
There is an office in Quellón at Avenida La Paz 068 that can answer all your questions. They also have a booklet with much more information than the website about the park that they can email (try calling or emailing them) or print out for you.
Parque Tantauco (Tantauco Park) was created in 2005, when Fundación Futuro decided to build a nucleus of local development in order to conserve the region’s unique ecosystems while boosting Quellón district and Chiloé Province.
In May 2005, advised by the “Corporación Chile Ambiente” corporation, Fundación Futuro began developing the "Management Plan for the Conservation of Parque Tantauco." In September of that same year, after the first infrastructure works were well underway, building of the Inio lodge, Tantauco’s center of operations, began.
February 2006 saw the inauguration of the Parque Tantauco offices in Quellón. As well as serving as the park’s administrative headquarters, the offices also serve as an information center for visitors. The Park is comprised of two campgrounds; 120 km of hiking trails; Chiloé Island’s southernmost museum, Museo Parque Tantauco; and various facilities for visitors wishing to enjoy nature and the zone’s beautiful landscapes.
The natural barriers separating Chiloé from Chile create special conditions that enable the existence of unique and valuable species and marine and land ecosystems on the Island.
In this context, public access to Parque Tantauco is an important opportunity given that its territory is located on one of the world’s 25 Biodiversity Hotspots (www.biodiversityhotspots.org) Moreover, its surface is part of “Sitio Chaiguata”, defined by Chile’s CONAMA (National Environmental Commission) as a priority spot for the conservation of wildlife.
Flora and fauna
The Park’s flora includes species such as the Guaitecas cypress (Pilgerodendron uviferum) and the coastal Olivillo (Aextoxicum punctatum); its fauna includes the huillín otter (Lontra provocax), the chilote fox (Pseudalopex fulvipes) and the blue whale (Balaenoptera musculus).
The Parque Tantauco climate is governed by its latitude, its altitude, the cold Humboldt current and the location of the territory as regards the sea. The zone’s climate can be classified as rainy cold temperate maritime climate on the western coast. Its distinguishing features include a permanent environmental humidity and high probability of precipitations throughout the whole year.
Maximum temperatures observed during summer stand at 27ºC. Although in general, the weather during summertime is pleasant, rain and cold temperatures are also to be expected. According to meteorological data recorded over recent years, average annual precipitation stands at approximately 2500mm.
The northern sector is accessed via 40 km of unpaved road (the first 18 good quality, the rest 4x4 is recommended) off of ruta 5. The southern sector is accessed by boat (lancha) which carries personnel and supplies (and tourists) from Quellón. As of March 2014 there are 3 trips a week (Mo-We-Fr) during high season (January&February) leaving from Quellon at 9:30 and returning from 15:00. During low season there are 5 boats every month. There is limited space on the boat, reserve your spot with the guardaparques office in Quellón. Fishermen go both ways about every other day and will carry you along for free or up to 10000 pesos. The ride takes 3 hours in speedboat and 6 with the fishermen.
As of March 2014, camping is 3000 a night on the trail and 3500 in the starting and ending point. Refugios cost 7000 but on the trail there is nobody to check which you are using. The boat from Inio to Quellon costs 28.000 Pesos. Entry to the park is 3500 Pesos. Check in the office in Quellón, there are very helpful and it is nice to let them know where you are going.
There are several trails available. The main trail is a 5 day hike from the mainland entrance Chaigata to Inio on the seaside with a possible 4 day extension towards the west coast to form a 9 day hike. There are many 1 or 2 day hikes and the possibility to go 8 days from Chaigata to the coast and back.
