Castlebar to Galway Bus Timetable

Both operators run five services each day, but the timing and stops differ in ways that matter.

Citylink Route 430 Timetable

  • Citylink operates 5 daily services between Castlebar and ATU Galway, according to its route network (Citylink (Mayo services)).
  • First departure approximately 07:00; last departure approximately 19:00.
  • Timetables are subject to seasonal changes; always check operator websites.
The trade-off

Citylink’s direct service saves about 45 minutes over Bus Éireann’s route, but its ATU stop rather than Galway city centre may matter for where you’re headed.

Bus Éireann Route 456 Timetable

  • Bus Éireann operates 5 daily services on route 456, which the operator describes as “Galway to Castlebar via Westport” (Bus Éireann (route 456 timetable)).
  • Departures from Castlebar are at 06:00, 09:00, 12:00, 15:00, and 18:00 (Bus Éireann).
  • First departure approximately 07:00, last departure approximately 19:00.

The pattern: Citylink wins on speed, Bus Éireann on coverage — you trade directness for frequency at more stops along the way.

Which Bus Companies Operate from Castlebar to Galway?

Citylink Overview

  • Citylink offers a direct service between Castlebar and Galway (ATU). Its Mayo services include the Ballina to Galway route (Citylink (Castlebar destination page)).
  • Online booking is available at citylink.ie.

Bus Éireann Overview

  • Bus Éireann route 456 is a regional service that connects Castlebar, Westport, and Galway (Bus Éireann).
  • Tickets can be purchased online at buseireann.ie or from the driver.
The catch

Bus Éireann’s route via Westport adds about 45 minutes to the journey, so riders heading to Galway for a tight connection may prefer Citylink’s direct line.

Why this matters: both operators are official transport providers in Ireland (Tier 1 sources), so timetable data from their websites is the gold standard for planning.

How Much Does the Castlebar to Galway Bus Cost?

Three price tiers, one reality: the cheapest fare isn’t always the best value when travel time is factored in.

Operator Single fare range Booking channel
Citylink €12 – €17 Online, driver, station
Bus Éireann €10 – €16 Online, driver, station

Citylink Prices

Bus Éireann Prices

  • Bus Éireann tickets typically cost €10–€16 (single) on the Castlebar to Galway route.

Discounts and Student Fares

  • Student and off-peak discounts may apply; check operator websites for current offers.

The trade-off: Bus Éireann’s lower starting price is appealing, but the extra travel time through Westport means Citylink’s €12–€17 fare delivers better time value for most travellers.

How to Book a Castlebar to Galway Bus Ticket

  1. Decide which operator fits your needs (speed vs. cost vs. destination).
  2. Book online at citylink.ie or buseireann.ie.
  3. Alternatively, buy tickets at Castlebar Bus Station or from the driver (cash or contactless).

Booking Online with Citylink

  • Citylink online booking at citylink.ie.

Booking Online with Bus Éireann

  • Bus Éireann online booking at buseireann.ie.

Buying in Person at Castlebar Bus Station

  • Tickets can also be purchased at the bus driver (cash or contactless).

The pattern: both operators offer the same three booking methods — online, station, driver — so the choice comes down to convenience and price, not process.

Bottom line: Citylink is what it is — the fastest option for Castlebar to Galway at €12–€17. Bus Éireann’s route via Westport is slower but offers slightly lower fares and more stop coverage. For price-conscious travellers without a tight schedule, Bus Éireann wins. For time-sensitive riders, Citylink is the clear choice.

Castlebar to Galway Bus Route and Stops

Citylink Stops (Route 430)

  • Citylink stops: Main Street Castlebar, Balla, Claremorris, Miltown, Tuam, ATU Galway.

Bus Éireann Stops (Route 456)

  • Bus Éireann stops: Galway Bus Station, Westport, Castlebar (and intermediate stops) (Bus Éireann).

Journey Time Comparison

  • Direct Citylink service takes approximately 1h 30m; Bus Éireann via Westport takes approximately 2h 15m.

The implication: choosing Citylink means getting to Galway in 1 hour 30 minutes, but arriving at ATU rather than the city centre bus station. Bus Éireann takes longer but drops you at Galway Bus Station, a central hub for onward connections.

The upshot

If your destination is Galway’s city centre, Bus Éireann’s longer journey may actually save you a second leg of travel from ATU.

The implication: choose based on destination – Citylink for speed to ATU, Bus Éireann for city centre access.
