Arusha National Park was Ngurdoto Crater Highland National Park until 1967. The current national park covers an area of 137 sq km/53 sq mi, and is located near the town of Arusha between Kilimanjaro and Mount Meru. The park and town derive their name from the Wa-Arusha people who traditionally live in this area. On this one-day excursion leaving from Arusha, Moshi or Kilimanjaro International Airport (JRO) you will get to know the Ngurdoto Crater, Momella Lakes, highland montane forest, and the rugged Mount Meru (4,565 m/14,977 ft). The park has a wealth of wildlife including Colobus Monkeys, velvet monkeys, bushbucks, buffalos, red forest duikers, hippos, elephants, and giraffes. Birdlife, especially waterfowl, is abundant and interesting.

The park is named after the river that flows through a rugged valley in the heart of the semi-arid central highlands of Tanzania. It covers twenty thousand square kilometres and is the largest park in the country. Ruaha is remote and difficult to access (usually by plane) but it offers visitors exceptional game drive opportunities.
