Highlights include Kadriorg Park's serene pond and the grand 18th-century palace and gardens, the evocative ruins of St. Bridget's Convent, and a photo stop at the Song Festival Grounds. Drive by Toompea Castle (home to the Estonian Parliament) and the Alexander Nevsky Cathedral, then finish with a lookout over Lower Town and some shopping.
