The Harold L. Lyon Arboretum is 200-acre of real nature rather than a cosmetically designed and landscaped garden. On the trails winding through this impressive scenery, you can find some of the most representative Hawaiian plants and trees, such as breadfruit and sugarcane, so do go here for a lovely and relaxing stroll.

The United States naval base at Pearl Harbor was surprised by a Japanese military strike on the morning of December 7, 1941: all eight U.S. Navy battleships were damaged, more than 2,000 Americans lost their lives, and this very attack led to the American involvement in World War II. Today, a memorial reminds of those who died in the assault, while two museums and outdoor exhibits present the historical happenings and their backgrounds. The visitor centre in general also features exhibits and interpretive programs for other Pacific National Parks: Kalaupapa National Historical Park on the island of Molokai, American Memorial Park in Saipan, and War in the Pacific National Historical Park in Guam.

The imposing Fort Saint-Louis, which towers 200 feet over a steep cliff offers some of the best views of both city and sea. The original construction dates back to 1640, but little of that remains, and what can be seen today is largely composed of later additions. Reopened in 2014, tours are now available in several languages.

This museum is the place to visit for anyone who wants to get a comprehensive idea of the history of Kenya, as it hosts a wide range of thematic exhibitions showcasing the county's rich historical, cultural, and natural heritage. The Snake Park and Botanical Garden are a must!
