The southern entrance to the park at Caleta Gonzalo was severely affected during the May 2008 eruption and completely shut down through 2009. Contact the park office for the latest news. When things are again in working order, you can get to Caleta Gonzalo and the southern section of the park from either Chaitén in the south, or by a 6-hour ferry ride from Hornopirén. (In years past, during Jan and Feb, the ferry left daily at 3pm from Hornopirén and 9am from Caleta Gonzalo; the ride takes 5 hours and costs $17/£11 per person, plus $107/£71 for a private vehicle. Outside of Jan. and Feb., visitors will need to go first to Chaitén to visit Pumalín. Reservations are necessary for vehicles; contact Transmarchilay, at Av. Angelmo 2187 [tel. 65/270000; www.transmarchilay.cl]).
