This small hotel has the feel of a backpacker's place, but it's in the park, which is what is important to most travelers. Although the Jaguar Inn is less expensive than the other two hotels in the park, rates are still a hefty US$80/Q625 double. The hotel has a pretty good restaurant. The small rooms have tile floors, fans, and wooden furnishings, with Guatemalan fabrics. You can also camp here for Q40 (US$5) per person, including rental of a hammock and mosquito net.
The inn optimistically promises electricity from a generator 24 hours a day. Internet available (about Q40 an hour). The hotel will pick you up in Melchor near the border for US$90 one-way for up to four persons.
