If you would rather spend the day trekking you can take whatever gear you usually use and feel free to leave seldom used items safely in your room at the ranch. Trekking can only be done at closer proximity to the ranch than on horseback as venturing too far out on foot can be dangerous and is not advisable. Take fast and slow speed film. If you are using a telephoto lens to photograph the incredible variety of birds you may want to use a little faster speed of film. However, another advantage of going out on horseback is that the birds and marsh animals are so accustomed to the invasion of fellow ranch horses that roam freely throughout the 17,000 hectares that they're not alarmed when riders with cameras appear.
Accommodation is simple and rustic but clean and comfortable.
This includes a private room with bath and three meals a day, unlimited use of horses, knowledgeable guides and all activities on the ranch. Corrientes is a subtropical lowland with very hot and humid summers. Wintertime is pleasant but can be rainy. There is no perfect time to visit. You'll want to arrange for a car to meet you at the airport in Posadas at the same time you book your accommodation.
