Overview
The Abbert (Irish: Abhainn na hAbarta) rises in the protected Killaclogher Bog Natural Heritage Area near Gortnahultra and runs roughly 41 km west to meet the River Clare at Anbally, from where its water reaches Galway Bay through Lough Corrib and the River Corrib. It is a small, lightly engineered river that holds brown trout and threads through low fields, native woodland and peatland. For visitors to County Galway, it is a change of pace from the coast and a quiet place to walk or fish.

Knockmoy Abbey
The most substantial thing to see along the river stands on the northern bank near Abbeyknockmoy: the Cistercian Abbey of Knockmoy, one of the better-preserved medieval monastic ruins in Connacht. It was founded in 1189 by King Cathal Crobhdearg Ua Conchobair and settled by monks from Boyle. The de Burgh family raided it in the early 13th century, and it was surrendered during the Dissolution of the Monasteries in 1542.
You can walk through the wide nave, the rib-vaulted chancel and the cloister garth, now a burial ground. The reason to come is the set of tempera wall paintings on the north wall of the chancel, depicting biblical scenes in weathered colour. They are one of only four surviving sets of medieval wall paintings in Ireland, which makes a small rural ruin worth a detour. The dedicated Abbeyknockmoy page and the Historic Environment Viewer have more detail.
Fishing
The Abbert is a quiet trout river rather than a famous one. It is mostly shallow, but the deeper pools and runs hold a healthy head of brown trout. The season runs March to October; April and September are the windows worth planning around, when olive hatches bring the fish up and reward fly fishing. Spin fishing works through the season, particularly in the calmer backwaters. The clear, peat-fed water rewards a delicate presentation, so lighter tackle and natural patterns tend to beat flashy lures. You need a valid national fishing licence and a local permit from the Tuam Anglers’ Association, who are also the best source for water conditions, access points and any seasonal restrictions.
Wildlife and walking
A gentle, mostly flat walk from Monivea to Abbeyknockmoy follows the river through farmland and scrub. It suits birdwatchers: kingfishers over the shallows, herons on the banks and waders passing through on migration. Killaclogher Bog behind it carries cotton grass, sphagnum moss and bog rosemary, with wildflowers in spring and russet bog colour in autumn. The trail works for families, dog walkers and anyone after the soft light of the midlands.
