Hello Arnaud,
Visit Derry are keen to assist you with any aspect of your stay in our corner of Ireland. I see you are not necessarily looking to stay in a City however for the Northern part of your tour, Derry~Londonderry would be the perfect base. With excellent transport links to both the Causeway Coastal Route and the Donegal Section of the Wild Atlantic Way you couldn't be more perfectly situated to explore our region.
The train line from Derry to Coleraine is regarded as iconic, passing several Game of Thrones locations on your way to the Giant's Causeway with excellent walking routes in the area also.
In the other direction you can reach Glenveagh and walk in the steps of our local Saint, Colmcille before hiring bikes to travel around Glenveagh National Park where, if you are lucky, you may see one of the Eagles which are resident in this beautiful area.
Check our website - www.visitderry.com to see what accommodation is available or email any queries directly to us at
info@visitderry.com, any of our team will be delighted to help you make the most of your visit.
We look forward to seeing you all in August.
Sam
