Leilani Says: We love the beach and we love camping—Assateague Island has both. Plus, this island is full of wild ponies. If you’re in the mood for a travel adventure, hightail it to this amazing kid-friendly U.S. road trip destination. In conclusion: wild ponies. Dash's Doggy Tip: Dogs are allowed on most of the beaches. Went for a swim, my doggy paddle is still flawless.
