Amazon Antonio Jungle Tours
On the scenic (and mosquito free!) Rio Urubú, northwest of Manaus, Amazon Antonio's lodge has dorms, private rooms, chalets, even a two-bedroom cabin across the lake and an observation tower. Overnight hikes journey deep into primary forest, and unlike elsewhere, you can stay after your tour is over, relaxing, canoeing, and soaking up the views. Somewhat pricier, but worth it.
