A short break on one lake, for small crews who enjoy quiet harbours, old stories and a bit of open water. Lough Ree Cruisers is a small family firm at Lough Ree Marina, Mucknagh, on the east shore near Glasson. Its six-berth cruisers have a sliding saloon roof and come with a dinghy, staff give every crew a handling lesson and a test drive, and beginners can have an instructor aboard for the first hour. The loop runs south to the town of Athlone, up the west shore to the small harbours of Lecarrow and Portrunny, and back across past the island monasteries of Inchcleraun and Inchbofin. There are no locks, but every day is on open water, so plan around the weather; the days are short enough to wait out a windy morning.
Good to know: This is a travel guide, not a navigation aid. Distances are estimates: the base sits in a small basin that OpenStreetMap shows apart from the lake, so the legs from and to Mucknagh, computed on our OpenStreetMap route network, start and end just outside its entrance, and all lake crossings are approximate. Times assume 7.5 km/h.
Day by day
Day 1 Night 1
Mucknagh → Athlone
16.3 km No locks 2.2 h under way
After the handover, run south along the lake towards Athlone. Hare Island lies off the southern end; tradition links it with St Ciarán before he founded Clonmacnoise. You pass Coosan Point, where the RNLI's Lough Ree lifeboat is based, and Lough Ree Yacht Club, founded in 1770, whose jetties are for members. Under the bypass bridge the river leads into Athlone. Moor above the weir at the council marina (about 60 berths, €15 a night, paid on arrival) or at the free public jetty on the west bank. Sean's Bar and the Left Bank quarter are a short walk away. Check the forecast before you leave the base: this is open water.

Day 2 Night 2
Athlone → Lecarrow
22 km No locks 3 h under way
Spend the morning ashore, at the Luan Gallery on the riverbank or on the first stretch of the Old Rail Trail greenway. Athlone Castle has been closed for redevelopment since October 2025, so check whether it has reopened. Then head up the lake. Hodson Bay, behind its breakwater beside the hotel, makes a good lunch stop on the Roscommon shore; in summer the Baysports inflatable water park floats off the shore. Further north, read the weather again before the open stretch to the Lecarrow Canal, a 1.5 km cut dug in the 1840s for limestone barges. Lecarrow Harbour has a service block with toilets, showers, a pump-out and shore power. Coffey's has live music on Wednesday nights.

Day 3 Night 3
Lecarrow → Portrunny
6.5 km No locks 1 h under way
Take the morning slowly: St John's Holy Well is in the village. Rindoon, the deserted royal town of 1227 on St John's Point, has no public access at present, and anchoring in its old harbour is not allowed. Check the forecast before the open-water run north. Inchcleraun lies in mid-water between Knockcroghery and Newtowncashel; its monastic ruins and the bell tower of Teampall Clogas can be seen from the boat. The monuments belong to the State but the farmland is private, and we know of no public landing. Portrunny's floating jetty, with 24 berths behind a breakwater, has shore power, a pump-out, toilets and showers. Local swimmers use the clear water by the jetty.

Day 4 Night 4
Portrunny → Mucknagh
14.9 km No locks 2 h under way
Before leaving, walk up the lane to Portrunny church and St Diarmaid's holy well, which tradition links with the saint's journey to Inchcleraun. The crossing back to the east shore is open water: check the forecast, and if the wind is strong, wait for it to drop. On the way you pass Inchbofin, the island of the white cow, where two ruined churches survive from a monastery said to date from about 530; again, there is no confirmed landing, so look from the water. Saints' Island, joined to the mainland by a causeway, lies near the base; its priory ruins are best visited on foot after you return the boat.

Before you go
- Book direct. Lough Ree Cruisers takes bookings for any start day and offers short breaks on request (+353 87 247 1762). Its website works on the http:// address shown above.
- Weather. Lough Ree gets rough quickly in a strong wind. Read the Met Éireann inland lakes forecast and the warnings on Today on the water every morning, and keep to the marked channel.
- Firing range. A Defence Forces firing range on the lake is marked by buoys carrying an X and the word "Danger", and boats may not enter it (Special Marine Notice 1/2026).
- Emergency. Call 112 or 999 and ask for the Coast Guard; the RNLI lifeboat is at Coosan Point.
- Smart Card. The service blocks at Lecarrow and Portrunny use a Waterways Ireland Smart Card.
- Bridges. All the bridges at Athlone are fixed; the lowest, the bypass bridge, leaves 5.15 m at ordinary summer level (IWAI).
- Busy weeks. In 2026 the Lough Ree Yacht Club regatta filled the southern lake in the first week of August, and the IWAI Shannon Boat Rally crossed the lake in late July; the 2027 dates are not out yet, so check our events.
- Daylight. Hire boats may not cruise after dark.

Weather and timing
Distances and times are estimates for planning, not for navigation. On the big lakes the wind matters more than the distance: read the forecast every morning and stay in harbour when it blows. Lock and bridge hours change with the season.
