Overview
Rehins Wood is where the Castlebar arm of the Great Western Greenway runs out. Cycle the 16km from the National Museum of Ireland – Country Life at Turlough, through Castlebar and past Lough Lannagh, and the tarmac finishes here at the trees. Coillte, which manages it as a NeighbourWood, calls it Raheens Wood; locally it’s Rehins. Either way it’s 33 hectares of native woodland about 4km north of the town on the Newport road (R311), and roughly 23 of those hectares are old woodland that has held ground since around 1840.
That age is the point. New conifer plantations are dark and dry; old broadleaf woodland is damp, layered and slow to build, which is what makes this one worth the short detour rather than the nearest forest car park to town.
Walking the trails
There’s a single waymarked loop, followed by red markers, and most people are round it inside the hour. The going is mostly flat and firm, with a gentle rise to the high point, where a gap in the canopy opens out across the countryside; on a clear day Croagh Patrick shows on the horizon. Some of the older sections near the tree line turn to mud after rain, so waterproof footwear is the sensible call for most of the year.
Interpretive boards along the way name the trees and ground flora, which makes it a handy spot for a school group or anyone learning to tell an Irish broadleaf wood apart.
The woodland itself
The canopy is a mix of hazel, birch, ash, oak and rowan, with bracken, woodrush and a heavy carpet of moss underneath. The combination of age and damp Atlantic air is exactly the kind of habitat that favours mosses, ferns and slow-growing lichens on the older trunks, and the site is birdy year-round in the undergrowth. It is a working conservation woodland rather than a wildlife spectacle, so keep expectations local: this is a good place to notice small things, not to tick off big ones.
History and heritage
The wider Rahins estate was the seat of the Browne family, Lords Kilmaine, from the Cromwellian period, and traces of that survive around the area, including an 80-foot obelisk raised as a cenotaph to Maria Browne O’Donel, and a canal dug as a Famine relief scheme to link Islandeady Lake with Clonkeen Lake. Down at Lough Lannagh, on the Castlebar side, a crannóg, an ancient lake dwelling dated to the time of the Clann Cuan, is still partly visible.
The wood was opened to the public through the NeighbourWood scheme, a partnership between Coillte, Mayo County Council and the Forest Service. An Taoiseach Enda Kenny, a Castlebar man, performed the opening and unveiled a plaque here to Seán McEntee.
Practical tips
- Entry and parking: Free, as with Coillte woodlands generally. The car park is on the R311 about 4km from the centre of Castlebar; look for the brown sign and the Coillte entrance.
- Facilities: Minimal. Bring your own water and anything you’ll want to eat; there are no shops or cafés at the wood.
- Dogs: Fine on the flat, shaded loop; keep them under control.
- Best time: Spring and early summer for the ground flora, autumn for colour in the birch and hazel. The loop stays open in winter, when the wet ground makes boots essential.
Getting there
By car it’s a straight run out the R311 Newport Road from Castlebar. There’s no bus to the wood itself; the nearest stops are in the town centre, a taxi ride or a long walk away. The most rewarding arrival is by bike: the Castlebar section of the Great Western Greenway drops you at the entrance, and if you’re already on the greenway, the wood is a natural place to turn around.
