Located on 99 acres of prime jungle and virtually on top of extensive and largely unexcavated Maya ruins, Lower Dover is an intriguing eco backpacker place where you can sleep cheap and explore some serious archaeological history. If you have your own tent you can camp, or take a bed in the bunkhouse.
The private cabañas range from basic with open-sky shower to extremely comfortable cabins on stilts. There are self-guided walks to Maya ruins (the dogs will help you find the way) or hire a guide for a BZ$10 donation. Other activities include canoeing, swimming in one of the seven river-fed swimming holes, fishing and birdwatching. There's also a house winery producing hibiscus wine.
