The crown jewel in beautiful Tanzania's coastal treasure chest and most famous for its idyllic setting and boutique beach hotels (not to mention outstanding scuba diving), Zanzibar is a must-visit while on a Tanzania beach holiday. Stone Town, the historical quarter of the island's capital Zanzibar Town, offers the inquisitive traveller the chance to explore twisting alleys, mosques and markets. Scattered around Zanzibar are tiny, off-the-beaten-track islands, offering an incredible location for those seeking a romantic honeymoon or a get-away-from-it-all vacation. This tropical island is good to visit at most times of the year, thanks to regular sunshine, however the best time to visit Zanzibar would be during the dry season from June to October.
