There is no direct travel route from Las Vegas, Nevada, to "Trinidad" as a single identifiable destination—because Trinidad is not a city but an island nation (part of Trinidad and Tobago) in the southern Caribbean, ~4,800 km (3,000 miles) southeast of Las Vegas.
A small city in southern Colorado (~200 miles / 3.5 hrs drive from Las Vegas, NM—not Nevada).
A coastal town in Humboldt County (~900 miles / 14 hrs drive).
By air: Fly Las Vegas (LAS) → Port of Spain (POS) via hub (e.g., Miami, Atlanta, Houston). Total 8–12 hrs.
