Puffins sit on a grassy cliff edge, with the blue sea sparkling beyond. A hat-shaped island can be seen in the distance.

Getting here

The Treshnish Isles are part of the Inner Hebrides, 4 miles west of Mull.
Address Treshnish Isles Isle of Mull Argyll and Bute

The easiest way to visit the Treshnish Isles is with one of the local tour boat operators, easily found online.

Most visitors go to the largest island (Lunga), which is also the most accessible. However, even landing on Lunga is highly dependent on suitable weather conditions.

Planning your visit

What to expect when you arrive

This short film by Trust Ambassador Cal Major gives a superb introduction to the Treshnish Isles.

The weather and sea conditions can change very quickly, and sometimes plans have to change. It is always advisable to be prepared for almost any weather for the boat trip out and once you arrive on the island.

Most boats landing on Lunga arrive at the boulder bay called Corran Lunga at the north-east end of the island. From there, you can explore the island at your leisure. Most visitors head straight for the wonderful seabird colonies. The birds can appear to be remarkably tame but please remember this is their home and they need a little space.

There are no visitor facilities, toilets or formal footpaths on Lunga.

The ground conditions are uneven with steep drops in places. Please take care.

We aim to have a ranger present on the island and much as possible to help you make the most of your visit and to look after the precious wildlife. Please take note of advice given by our rangers.

Please do not bring your dog to Lunga

The Treshnish Isles are a haven for ground-nesting birds such as puffins, shags and storm petrels. In line with other important seabird islands, we ask that during the breeding season (1 April to 30 September), when the birds and their young are particularly vulnerable, dogs are not brought to Lunga.

Dog-sitting services are available on Mull and the mainland. Where no alternative has been possible to arrange, your dog, on a lead at all times, may land on the beach at Corran Lunga and remain there. Dogs must not be allowed up to the puffin colony.

Many seabird populations are currently under increased pressure from avian flu and changes to the prey they depend on. Keeping dogs away from their breeding sites at particularly vulnerable times is one way to help relieve any additional stress on these populations. We are grateful for your support.


The Treshnish Isles are a ‘no-drone zone’ between 1 April and 31 July, to prevent disturbance to breeding seabirds. Outwith this time, amateur unmanned aerial vehicle (drone) operators should seek permission from the property before flying. Commercial operators should contact the Trust’s Filming Manager at

Landing charges are applicable for commercial operators. Please contact for more information.

Avian flu

Avian flu (H5N1) is still potentially affecting seabirds. The risk to human health is very low but you may see dead birds on your visit, so please follow these simple rules to keep yourself safe:

  • Do not touch any dead or dying bird
  • Wash your hands before eating, drinking or smoking
  • Report any dead birds to Trust staff, either in person, or using the contact details above. If dead birds are marked with paint, then they have already been counted so there is no need to report them.

H5N1 is a highly infectious disease in birds and can be spread through their faeces. You can help limit the spread to other places and species by keeping your distance from the birds and by checking for notices on the island about areas to avoid.

If you have been to, or are going to, another seabird colony or have birds at home please:

  • Thoroughly clean your boots, especially the soles
  • Wash your outer clothing

Thank you for your support.

Facilities & access

  • Due to the terrain, access onto the Treshnish Isles is not advisable for wheelchair users.
  • For those with mobility difficulties, some tour boats are accessible with assistance.
  • There are steep, rough and narrow paths to the cliff tops and the top of the island.

We have an ongoing programme of accessible content development. Detailed accessibility guides for the most visited Trust places are available on our Accessibility pages as well as links to useful resources.

We’d love you to visit the Euan’s Guide website to review the accessibility of Trust places and tell us (and others) what’s good and where we need to do better.

Please note that there are unfenced, steep cliffs around most of the islands.
