Hello Raimondo,
Welcome to our Community! Wow, you've drafted a truly rich and challenging itinerary!
First of all, it's not difficult to find pubs with traditional music even in the most remote parts of the island. Depending on the area you're visiting, you can ask locals for advice about places where you can enjoy the most authentic atmosphere, or just let the island surprise you with unique places along the way.
The Benwee Head Loop hike is a strenuous, but beautiful, loop walk, and after reaching the summit and coming back down, you may want to take some time to
relax on the lovely beaches nearby. However, if you're still up for some activity, you may drive to Achill Island and enjoy its beautiful scenery.
Ashlem and its White Cliffs are definitely a great option for a stop, as they're not so touristy as they are located in a somewhat remote area and accessible via narrow, winding roads. Also, the view from the top of Minaun Heights is unbeatable. From here you overlook Ireland's largest island, Achill Island, Blacksod Bay and Clare. Both these places are less touristy than Keel.
Regarding Upper Diamond Hill Trails, Coral Strand and Connemara,
these are beautiful areas with great views and landscapes that are definitely worth a visit. It's just a matter of preference to dedicate time to one place or the other. As you already know, it may take more time than you think to explore places in Ireland in deep, both due to narrow roads or beautiful views that stop you along the way. So my advice is to plan fewer stops and leave some time for improvisation.
Given the fact that you'll be here in August, which is high season in Ireland, the Ring of Kerry may be more crowded than usual. The
Ring of Beara, the
Copper Coast and
Mizen Head may be interesting alternative routes. The
Dingle Loop may also be a good option.
Lastly, as you're going to sleep in a tent along the way, I suggest that you take a look at this useful thread with advice and recommendations for
legal alternatives to Campsites. I hope this helps!
Have a great day!
