Hen Island or Taranga lies separate from the rest of the Hen and Chicken Islands chain, lying 7 km (4.3 miles) to the southwest. It is also considerably larger than the Chicken Islands, or Marotiri, which comprise a chain of five small islands running northwest to southeast to the north of Hen Island. The chain consists of Wareware and Muriwhenua Islands (together forming North West Chicken), Mauitaha (West Chicken), Lady Alice Island (Big Chicken or Motu Muka), Whatupuke (Middle Chicken), and Coppermine Island (Eastern Chicken).
Taranga is the largest island by some considerable margin, totaling 4.7 square kilometers (2 square miles). Long and thin, it has a length of 6 km (3.7 miles) and an average width of less than 1,000m (1,094 yards). A remnant of a four-million-year-old volcano, the island is dominated by a rocky ridge reaching to about 417m (1,368 feet) at its highest point, called "The Pinnacles". Sail rock, a stack, rises from the ocean 3 kilometres (1.9 mi) to the south of Hen Island and is a prominent navigational point for yachts.
