Biking -- Free Bikes, at Las Fucsias and Los Notros (tel. 02944/495047; www.freebikes.com.ar), has a large selection of rental bikes for $3 (£2) per hour, $11 (£7.45) up to 6 hours, and $14 (£9.45) for a full day. They also guide a number of different mountain-bike trips.
Fishing -- Anglers typically head to the renowned Río Correntoso for rainbow and brown trout, reached just before crossing the bridge just outside town on Ruta Nacional 231, from the Siete Lagos road. Banana Fly Shop, at Arrayanes 282 (tel. 02944/494634), sells flies and gear, and they provide information and can recommend guides. You may pick up a fishing license here or at the Bosques y Parques Provinciales office at the port (tel. 02944/494157); it's open Monday through Friday from 11am to 4pm, Wednesday until 2pm, Saturday and holidays from 2:30 to 5pm.
Horseback Riding -- Hop on a horse and ride up to the top of the ridge for views of all the area lakes. Organized by a well-known local character, Cabalgatas Correntoso (tel. 02944/624221; www.cabalgatacorrentoso.com.ar) has rides from 2 to 9 hours, and overnight pack trips.
Skiing -- Villa La Angostura is home to a little gem of a ski resort, Cerro Bayo, located about 9km (5 1/2 miles) from downtown. It's a smaller resort than the one at Cerro Catedral, but the crowds are thinner and the view is wonderful. For those reasons, I almost prefer it. There are 250 skiable acres. About 40% of the terrain is intermediate, and 35% is advanced. To reach it, you'll need to take a long lift from the base up to the summit; during the summer, this same chairlift provides access to an excellent short hike and lookout point. Cerro Bayo has ski and snowboard rental and instruction; the season runs from mid-June to mid-September, although it can get fairly patchy toward the end of the season.
To get to Cerro Bayo, ask your hotel to arrange transportation or hire a taxi for the short ride. Tickets are $21 to $27 (£14-£18) for adults, $14 to $21 (£9.45-£14) for kids, depending on the season. Kids 5 and under and adults 66 and older ski free. Half-day tickets, 3-day tickets, and weekly passes are also available. For more information, call tel. 02944/494189 or visit www.cerrobayoweb.com.
