We went on the dune tour sort of a last minute, late afternoon, what do you want to do sort of thing. But, we ended up being very glad we went. The dunes are beautiful with sweeping views. This is the only way to get atop the dunes and it is worth the ride. The info our driver gave about the shacks was quite interesting too. We did not take the extra hour for the sunset tour, instead we went to Herring Cove on our own for a magnificent sunset. I recommend that or Race Point Beach. I guess that isn't fair since we didn't take the sunset tour I don't know what we missed, but I do know what we did, was terrific, and Art's Dune Tours started our evening off beautifully.
