Inside the Park
The park's official tour operator is Iguazú Jungle Explorer (tel. 3757/421-696; www.iguazujunglexplorer.com), located both inside the national park and in the Sheraton Internacional Iguazú. This company offers the Nautical Adventure tour ($30/£20), which visits the falls by inflatable raft; the Ecological Tour ($20/£14), which takes you to Devil's Throat and lets you paddle rubber boats along the Upper Iguazú Delta; and the Gran Aventura (Great Adventure) tour ($50/£34). This last tour begins with an 8km (5-mile) safari ride along the Yacoratia Path, the original dirt road that led through the forest and on to Buenos Aires. During the ride, you'll view the jungle's extensive flora and might catch a glimpse of some of the region's indigenous wildlife. You will then disembark at Puerto Macuco, where you'll hop into an inflatable boat with your tour group and navigate 6.5km (4 miles) along the lower Iguazú River, braving 1.6km (1 mile) of rapids as you approach the falls in Devil's Throat Canyon. After a thrilling and wet ride, the raft lets you off across from San Martín Island. From there, catch a free boat to this island with excellent hiking trails and a small beach for swimming and sunbathing. You can combine the Ecological Tour and Great Adventure by buying a full-day Pasaporte Verde for $60 (£41). An increasingly popular tour is a guided walk around the falls under a full moon, where nighttime rainbows appear.
If you want to arrange a private adventure tour for your specific interests, the best outfit is Explorador Expediciones, with offices in the Sheraton Internacional Iguazú and in Puerto Iguazú at Perito Moreno 217 (tel. 3757/421-632). The guides are experts on life in the Iguazú jungle. A jungle safari costs $35 (£24) and an excursion to the waterfall $25 (£17). English guides are available, and tours last 2 hours.
