Highlights of Northern Mariana Islands are:

  • Unique submarine volcanoes – research of the submarine volcanoes north from Farallon de Pajaros has revealed several phenomena very rare or unique on Earth.
  • Beautiful, rugged nature of the Northern Islands. These small islands are tops of steep, active volcanoes and are covered with pristine tropical vegetation.
  • Latte stone settings – unique megalithic structures, found only in Mariana Islands. The largest megaliths are found in Tinian and Rota islands.
  • Petroglyphs. In several caves in Rota, Saipan and Tinian are found interesting, prehistoric drawings.

Once upon a time (no one knows when) somebody planned to make the largest megaliths in Mariana Islands. It was planned to erect up to 7.6 m tall stone columns, capped with 1.5 m high capstones.

Unfortunately this project was not a success. The giant stones were left lying in Rota Latte Stones Quarry.
