Hotels
Three hotels located next to the park entrance provide decent but basic accommodation. All three cater to Western travellers and their amenities and prices reflect this. For those on a shoestring, try asking if you can rent a hammock, or just a spot to hang your own, under a palapa roof.
Many people prefer to stay in the park and wake up with the jungle to the sounds of birds and nature rather than the rickshaws of Flores, and staying here is the only way to be in the park for sunrise. Unfortunately the park options are not the cheapest, and demand often exceeds supply. Many stay in Flores and take an early shuttle bus to the park. There are also several cheap lodges lakeside in El Remate, where your hotel can arrange a shuttle pick up for you.
camping
For the budget traveler there is a camp site Q50 per person or per site, not sure which. They have tents you can rent if you didn't bring your own Q50. At the Jaguar Inn, you can get into the jungle mood by renting hammocks with a mosquito net, access to showers and toilets, or a place to hang your own. Sleeping in a hammock is a surprising comforatable way to sleep. Many of the locals do it.
If you need your bags kept securely there is an additional Q5 $0.80 US fee. There are alot of insects that bite, mosquitos aren´t that bad during the dryer months but there are other nasty insects about. Keep the fly wire screen on your tent zipped tight and get in and out of your tent as quickly as possible. A can of bug spray would be very helpful. There are a lot of bees on the lawn in the camp area so wear something on your feet.
