I'd highly recommend doing the 2 1/2 guided walk with Tony Kirby. I just did it this morning under a blazing summer sky in the heart of the Burren. I had the most amazing and informative time and it was truly wonderful.
Tony's knowledge is unsurpassed and covers all the historical periods of the Burren. The detail regarding the rare plants and flowers associated with the Burren was an eye-opener. Fantastic value at €20 and he even includes a wonderful verse of poetry as well. For this particular guided walk, we started outside Cassidy's Pub in Carron.
