Ie i dont know what are the nice places to visit. Time for some random ness
My suggestions along the west (mainly in geographical order)
Slieve league cliffs
Killybegs – proper fishing town
Avoid bundoran
Yeats grave in Sligo
Kilcullens Seaweed Baths, Enniscrone
Cliffs of Moher
Tarbert ferry
(The lonely) Banna strand
Not Tralee
I would swerve doolin as well
Killirglin – Puck Fair is on 10-12 august so the town will be rammed for that, otherwise the town has died a bit
Kells for a beach swim

Ballinskelligs ring
Hake hatch in Ballinskelligs
Valentina island – visit the cliffs
Kimego forest for wild camping after a swim at the beach at Cooscrome
Knocknadobar Mountain, Stations of the cross walk. A good walk with spectacular views. You could probably wild camp on top of the weather was ok and you’re feeling hardy!!!
The Moorings at portmagee for a pint
O’Neils at Renard point for a pint and a lobster ( great place by the Valentina ferry – doesn’t take reservations)
Head northish to Glencar for some excellent roads, Bealach Oisin and Bealach Beama. Just after Bealach Beama you can cycle up past Lough Brin and into the Black Valley and then up through the Gap of Dunloe to Glencar – imho one of the most beautiful routes in Ireland
Climbers inn at glencar for pint and lodging
Walk up Carrauntoohil (this is a proper walk with scrambling and occasional deaths so not to be taken lightly. There are guides and groups in the area)
Gap of Dunloe and The Black valley
Sneem and Kenmare
Glengarrif and Garnish Island
Healy and Caher passes
