Hacienda Concepción is a good option if you want to experience the rain forest if you are short on time. Occupying the site of a 19th-century hacienda, it’s set inside an 809-hectare (2,000-acre) private nature reserve with a small lake and plenty of wildlife. Accommodations are pretty stylish; guest rooms are outside the jungle, sharing the main lodge with the restaurant and bar. Spacious, thatched bungalows have screened walls and a sitting area with a hammock. Those bungalows in the front overlook a seasonal branch of the lake; those in the back look onto the bungalows in front. They’re all close enough to hear your neighbors. You can enjoy excellent guided tours to Lago Sandoval, the Canopy Walkway, and other local attractions. The wildlife spotting is not as good as deeper in the jungle, but is great if your time is limited.
As well as mountains and rivers, Peru has a huge amount of rainforest, and the Amazon Basin counts for over half of the rainforest in the world. Incredibly diverse wildlife can be pointed out by your guides and there are some fabulous lodges and superb riverboats to get you around.
