Ecuador is the most biodiverse country in the world. Ecuador has over one hundred different types of hummingbirds and thousands of orchid varieties. Cuyabeno Wild Life Reserve, Mindo and San Luis de Pambil are all good places to see many types of flora and fauna. The Galapagos Islands are justly famed for their wildlife.
The Cuyabeno Wild Life Reserve is probably the best place to see the Amazon Rainforest in Ecuador, even though there are other national parks which are also interesting (such as the Yasuni National Park). It's a place of high biodiversity and nature lovers should feel in paradise. That's a good way to discover the indigenous communities of Ecuador and to eventually meet a local shaman. It's necessary to get to Lago Agrio to reach the reserve. Private transportation is made possible by the local accommodation, which is provided by eco-lodges.
The beaches in Ecuador are amazing, including: Salinas, Bahia de Caraquez, Manta, Crucita, San Jacinto, and San Clemente. They offer very inexpensive hotel accommodations, great food and friendly people. But there are also very upmarket establishments as well.
