Big Island of Hawaii: 90 Miles North to South (Upolu Point to South Point)

On the Island of Hawaiʻi (Big Island)—the only island where "north to south" makes sense—the distance from Upolu Point (north) to South Point / Ka Lae (south) is ~145 km (90 miles) as the crow flies.

Driving Distance

• Via HI-11 / HI-19 (coastal loop): ~200 miles, 4–4.5 hours.
• Via Saddle Road (HI-200, cross-island): ~120 miles, 2.5 hours (but misses coast).

Extremes

• Upolu Point: Northernmost, wind-swept, ancient heiau (Moʻokini).
• South Point (Ka Lae): Southernmost point in entire United States. Green sand beach (Papakōlea), fishing cliffs, strong currents.

Other Islands

Hawaii is an archipelago. "North Hawaii to South Hawaii" across islands = meaningless (Kauaʻi to Big Island = 300+ miles ocean).

The Big Island alone is 4,028 sq mi—larger than all other Hawaiian Islands combined.
