Bus nos. 249 and 23 will take you from just outside Nahuizalco to each of the route's small towns. Once in each town, you'll be able to walk to whatever you'd like to see, except for the few hotels and restaurants that are scattered along the main highway. Las Rutas does not offer any taxis, but taxi driver Israel Rodriguez (tel. 503/7734-7598) in Sonsonate can take you from Sonsonate to Las Rutas and from town to town along the route for $15 to $25. Juayúa also offers three-wheeled moto-taxis, which you'll find along the square and which will take you anywhere in Juayúa for less than $1.
