Overland means traveling across land rather than by sea or air. When pioneers crossed America in covered wagons during the 1800s, they made the overland journey from Missouri to California or Oregon, a trip that took months of hard travel over plains, deserts, and mountains. These routes became known as overland trails.

The word makes most sense when contrasting land travel with other options. Before airplanes existed, people traveling from New York to California could either take a ship around South America (a sea voyage of several months) or make the shorter but harder overland trip by wagon or train. Today, hikers might take an overland route through a national park instead of paddling across its lakes, or a family might drive overland from Texas to Canada rather than flying.

Overland suggests journey and distance: you wouldn't say you traveled overland to your friend's house down the street, but you might describe an overland expedition across the Australian Outback or an overland supply route through the mountains. The word carries a sense of adventure and endurance, of crossing terrain that takes real time and effort to cover.
