Kuching is a fine choice for an enriching vacation that's as packed with learning as it is leisure. Its many museums and impressive planetarium will enthrall even the tiniest travelers, and a quick climb to the top of the Kuching Civic Center will reward you with jaw-dropping 360-degree views. Grab a snack from a stall on the bustling waterfront, and don't miss the absolutely massive Sunday market, which is an electric experience for shoppers, vendors, and observers.

A group of islands and islets some 25 miles off the Tanzanian coast, the Zanzibar Archipelago is headlined by Unguja (often referred to simply as Zanzibar) and Pemba. Once a separate nation, Zanzibar has a long history of trade with the Arab world, dating back to at least the 11th century. The capital, Stone Town, is a UNESCO World Heritage Site and has many interesting historic attractions. Zanzibar's bright white beaches and nearby coral reefs make it very popular with the sun and sea set.

Inhabited since the 11th-century, what is now Kigali has been the home of Twas, Tutsis and Hutus. The city sits on a series of verdant ridges and lush valleys, and has a Muslim Quarter and a bustling market. Rwanda's capital is the site of battles that left over a million, mostly Tutsi and moderate Hutus, dead. Kigali Memorial Centre is a permanent memorial to 1994's Genocide, built on a mass grave where 250,000 are buried. Kigali City Tour Bus offers an excellent introduction to this now safe, friendly city.
