The Grand Canyon 
Grand Canyon National Park is a UNESCO World Heritage Site that is located entirely in northern Arizona and is one of the great tourist attractions in the US. The Canyon is an overwhelming experience, and nothing can prepare a visitor for the sight; superlatives often fail to do the landscape justice. The Grand Canyon is a massive canyon carved over several million years by the Colorado River.

Arenal Volcano 
The Arenal Volcano rises 1657 metres above sea level and overlooks Lake Arenal. Both are part of Arenal Volcano National Park. The country's most active volcano, Arenal's eruptions are strombolian in type, being frequent but moderate and can be viewed without danger as long as the viewers are behind the safety perimeter.
