The Lenca access point serves as one of two entrances to Alerce Andino National Park, situated along Río Chaica in the Los Lagos Region.

From Puerto Montt, visitors take Route 7 toward Caleta La Arena and, roughly one kilometer past the Lenca bridge, turn onto a gravel road (Route V-70) that continues approximately seven kilometers to the park entrance.

This sector, known as the Chaica sector, offers several trails open year-round, including routes to the Salto Río Chaica waterfall and a millennia-old Alerce tree.

Additional trails leading to Laguna Chaiquenes and Laguna Triángulo are accessible only in summer, as they require crossing the Río La Plata. Camping facilities for hikers and picnic areas are also available within this sector.
