The occasional sweat and effort make Costa Rica’s spectacular landscapes and abiding serenity all the more rewarding from a bicycle saddle. Sure, you’ll work for your reward. But you’d never get so close to so much beauty in a car. Away from the main highways, roads are little traveled.

However, there are no bike lanes, potholes are a persistent problem, and traffic can be hazardous on the steep and windy mountain roads. Leave your touring bike at home: Bring a mountain bike or rent one once you arrive. A helmet is essential.

Costa Ricans are fond of cycling (both road racing and mountain biking), and bicycle racing is a major Costa Rican sport, culminating each November in the grueling La Ruta de los Conquistadores (tel. 506/2225-8295, www.adventurerace.com), which crosses the mountain chain from sea level to over 3,000 meters.

Airlines generally allow bicycles to be checked free (properly packaged) with one piece of luggage. Taca (www.taca.com), for example, still permits free transport of bicycles.
