Day one: Chile Travel identifies La Araucanía Airport, ZCO, near Temuco as the gateway; Pucón's tourism office gives about 90 minutes by car, before collection/check-in. Public transport needs the airport–terminal leg and the ticketed destination/stop. Leave bags in Pucón, then choose La Poza's lakeside or Playa Grande's volcanic sand, distinguished by the municipal page, a meal and tomorrow's meeting point. Late arrival can mean dinner and rest; boats/paddling need separate bookings, conditions and return.
Day two: Huerquehue's Los Lagos shorter circuit connects Chico, Verde and Toro lakes, with araucarias in the upper forest. Chile Travel gives 13 km return, intermediate difficulty. Agree the larger walking commitment, transport and return; the hiking guide covers preparation. If no suitable park route is available, swap with Villarrica's cultural day. If neither supports the desired hike, keep town and another confirmed local visit rather than improvising a mountain route.
Day three: follow Pucón → Villarrica → costanera → a confirmed Liquen program → Pucón, with a waterfront walk and lunch. The costanera description starts at Julio Zegers and General Urrutia. Liquen, Prat 880, offers an exhibition, performance or public visit only through its actual program. Confirm both bus legs; a late performance may need a different return.
Huife can replace the cultural day, rather than follow Villarrica or the long forest hike. Termas Huife lists no own transfers as checked 4 October: arrange Pucón → Huife → Pucón, entry/walking needs and pickup, with time for changing, selected pools and lunch. Admission does not provide the ride home.
