Boho is the only example of a joint controlled maze cave in Northern Ireland. With 1.5km of explored passage, it is the seventh longest cave system in NI. The site also contains karst features such as episodic surface rivers and an episodic waterfall, a limestone gorge and a river bed with a series of bank risings. Chambers within the cave system are decorated by calcite straws, stalactites, stalagmites, flowstone, curtains, gour pools and canopies.
The area of mixed woodland supports toothwort, wood fescue, bird's-nest orchid and thin-spiked wood sedge.
A population of Daubenton's bat is present in the caves. Invertebrates include the troglobitic Collembolan Schaefferia emucronata and a large population of the common cave spider Meta menardi. The only modern Irish record of the cave dwelling water beetle Agapus biguttatus is from Boho caves.
