If you are looking to do Doolin, yes the Cliffs of Moher Visitor centre is very touristy and very popular with day tour buses from Dublin, Kerry, Galway. But just going a little off the beaten track and you are open to a total different experience and have the Cliffs virtually to yourself.
1) Hike the Cliffs of Moher Coastal Hiking Trail, it starts at Fisher Street in Doolin, 7km to the visitor centre and 12km to the other end Hags head, and hands down the best way to experience the Cliffs. Take in an evening sunset if you can as it sets on the Atlantic horizon.
2) Doolin Cave (largest stalactite in the Northern Hemisphere, 3rd longest in the world)
3) Nightly trad session in the local pubs, recommend Sunday to Wednesday nights which have some of the best music sessions or check out the Doolin Music House. The pubs are popular with live music every night all year round, so you are always guaranteed a good night out.
4) Explore The Burren, in my humble opinion the most under rated and most beautiful area in Ireland. From stunning lunar landscape of limestone, unique flora (May in Bloom), Paleolithic monuments, ring forts, castles, 160km of hiking trails etc. and with its unique terroir it gives an amazing minerality flavour to local meats, cheeses and other local produce. Its also a natural playground from rock climbing and bouldering enthusiast.
5) Day trip to the Aran Islands (March to November 1st) and take in a Cliffs of Moher Cruises.
6) Do something a little different and bespoke like SeaCliff climbing, Horse riding on the beach, learn to Surf, Sea kayaking etc.
7) All accommodation in Doolin is family run and to a high standard with a variety of choice from camping, B&B, Boutique Inn to Hotel. There is some great shopping locally supporting local designers and craftsmen.
8) Doolin is also the ideal central base to explore North Clare, surround by its villages and towns, and Galway (1.5hrs) or Ennis and Bunratty (1hr) for a day trip, Loop head (1 hr)
Hope this helps
