Except in nearby towns, accommodations and food are few. Organized campgrounds with hot showers and other services charge slightly more than so-called agreste (wild) sites, which cost around US$2 pp.
Alongside the Gendarmería post, facilities at Camping Lanín (tel. 02972/49-1355) recently suffered a fire that has left its immediate future in doubt.
Reservations are essential for the six twin rooms at Hostería San Huberto (RP 60 Km 28, tel. 02972/42-1875, www.sanhubertolodge.com.ar [1], US$300–375 s, US$440–560 d, with full board), which appeals chiefly to fly-fishing fanatics.
Free rustic campgrounds line the shores of Lago Huechulafquen and Lago Paimún, but the community-oriented sites that charge a fee are better maintained and have better services.
Camping Bahía Cañicul (RP 61 Km 48, US$4 pp) has a small store, but supplies are cheaper and more diverse in Junín. Camping Raquithué (RP 61 Km 54) costs US$3 pp for anyone over age 6. Only those older than 10 pay at attractive Camping Piedra Mala (RP 61 Km 60, US$4 pp); campers age 10 and under pay only a small charge for showers.
A few kilometers before Lago Paimún, Hostería Huechulafquen (RP 61 Km 55, tel. 02972/42-6075, www.hosteriahuechulafquen.com [2], US$105 pp with half board) is pleasant enough. Hostería Paimún (RP 61 Km 58, tel. 02972/49-1758, hosteriapaimun [at] jdeandes [dot] com [dot] ar, US$92 pp with half board, US$105 pp full board) is primarily a fishing lodge.
Basic Camping Puerto Arturo is free of charge.
Westbound from San Martín, gravel RP 48 follows Lago Lácar’s north shore to the Chilean border at Hua Hum. En route, open mid-December through Semana Santa, Estancia Quechuquina (RP 48 Km 30, tel. 02972/42-5340) is a rustic teahouse with exceptional cakes and cookies; hours are noon–7:30 p.m. daily for lunch and tea. Though lacking accommodations, it enjoys lake access and makes an ideal day trip.
