Hello again, Danish!
What a great idea to go stargazing! :) Ireland is home to two Gold Tier International Dark Sky Places
, and they are both located on the west coast.
The first option, and closest to Dingle, is the Kerry International Dark Sky
Reserve. You can book a tour
with a guide around the area and learn all about the constellations and more.
The second option is the Mayo Dark Sky Park
, where you can go on a tour
with one of the knowledgeable guides who can show you the night sky in the Nephin Mountain Range and along the Atlantic coastline.
If you reach out to the the Kerry International Dark Sky Reserve and Mayo Dark Sky Park directly they would be more than happy to tell you about the options. I also think this other thread about Stargazing
might have some interesting information and resources for you.
I hope this is the information you are looking for, and that you'll receive more suggestions from our other members. :)
