Founded in AD 573, this enchanting mini-monastery stands hidden among dense woods 11km south of Luintra. It contains three cave chapels, originally carved out of the rock as retreats for early hermits, plus a number of rock-cut graves from the 10th century onwards. The adjacent interpretation centre has interesting displays on the Ribeira Sacra. You can also take a lovely walk from here along the Camiño Real (PRG4), a 9km circuit trail looping through this picturesque area.
To drive direct from Ourense, take the OU536 east as far as Tarreirigo. Here, 500m past the Km 15 post, turn left on to the OU0509 and follow signs along minor roads for 4km through the forests to the monastery. Afterwards you can continue north to Luintra on the OU0509.
