Title: $185 Cheap Flights to Treshnish Isles - Expedia.com ![I highly recommend the Puffin boat tour with Turus Mara on the island of Mull. If you are staying in Oban you can book at the ferry terminal which includes a ferry to Mull, shuttle across Mull to the harbour to meet the tour boat. Remember to pack a lunch. Words cannot describe the experience of having a few hours seeing these beautiful birds so close up and so many. The photo shows one looking up watching a seagull glide across the cliff top. There are also fulmars and razorbills. You will also be taken to Fingals Cave on the island of Staffa. ](https://images.trvl-media.com/place/6093001/66a1c5f8-ed84-4204-8bfd-3bd8a85b38c0.jpg?impolicy=fcrop&w=1200&h=500&q=medium) Photo by Theresa George ![](https://images.trvl-media.com/place/6093001/66a1c5f8-ed84-4204-8bfd-3bd8a85b38c0.jpg?impolicy=fcrop&w=1200&h=500&q=medium) # $185 Cheap Flights to Treshnish Isles [View $185 flight on Sun, Mar 1, 2026](https://expedia.com/Flights-Search?trip=oneway&leg1=from:BOS,to:GLA,departure:3/1/2026TANYT&passengers=children:0,adults:1,seniors:0,infantinlap:N&mode=search&options=sortby:price&paandi=true&flp=mdl:flights-flex-module,price:184.30&airProductToken=AQplCjEIxpIBEgM2MzAYwZMBIIopKJLAhgMwzcKGAzhPQABYAWoFTElHSFRyCE9KMVFVU0xUCjAIxpIBEgM0MzAYiikg5gIop8OGAzCzxIYDOE9AAVgBagVMSUdIVHIIT0oxUVVTTFQSCggBEAEYASoCRkkYASIECAEQASgCKAMoBDAB) - [Roundtrip](?flightType=roundtrip) - [One-way](?flightType=oneway) - [Multi-city](?flightType=multicity) ### Travelers Adults ChildrenAges 2 to 17 InfantsYounger than 2 EconomyPremium economyBusiness classFirst class Leaving from Going to Departing Returning Add a place to stay Add a car Direct flights only [Treshnish Isles Travel Guide](https://expedia.com/Treshnish-Isles.dx6166247)[Hotels in Treshnish Isles](https://expedia.com/Treshnish-Isles-Hotels.d6166247.Travel-Guide-Hotels)[Car Rentals in Treshnish Isles](https://expedia.com/Car-Rentals-In-Treshnish-Isles.d6166247.Car-Rental-Guide)[Treshnish Isles Vacation Packages](https://expedia.com/Treshnish-Isles.d6166247.Destination-Travel-Guides) ## Popular airlines - ![](https://forever.travel-assets.com/flex/flexmanager/images/2024/09/23/landing_airline_sq_logo_BA.svg) British Airways - ![](https://forever.travel-assets.com/flex/flexmanager/images/2024/09/23/landing_airline_sq_logo_KL.svg) KLM - ![](https://forever.travel-assets.com/flex/flexmanager/images/2024/09/23/landing_airline_sq_logo_LH.svg) Lufthansa - ![](https://forever.travel-assets.com/flex/flexmanager/images/2024/09/23/landing_airline_sq_logo_EI.svg) Aer Lingus - ![](https://forever.travel-assets.com/flex/flexmanager/images/2024/09/23/landing_airline_sq_logo_AF.svg) Air France - ![](https://forever.travel-assets.com/flex/flexmanager/images/2024/09/23/landing_airline_sq_logo_VS.svg) Virgin Atlantic - ![](https://forever.travel-assets.com/flex/flexmanager/images/2024/09/23/landing_airline_sq_logo_IB.svg) Iberia - ![](https://a.travel-assets.com/travel-assets-manager/pictogram-bex/light__notification.svg) ### Be in the know Get alerts if flight prices drop or rise\* - ![](https://a.travel-assets.com/travel-assets-manager/pictogram-bex/light__deals.svg) ### Book smarter Save up to 30% on select hotels after you book a flight\* - ![](https://a.travel-assets.com/travel-assets-manager/pictogram-bex/light__trophy.svg) ### Earn twice Earn your airline miles on top of our OneKeyCash [Learn about One Key](https://www.expedia.com/welcome-one-key) ## How much is the cheapest flight to Treshnish Isles?
