Which island is the hardest to reach? A concise guide to the contenders

# Why "hardest to reach" isn't just about distance

# The contenders and why they're hard to reach

Farallon de Medinilla (Western Pacific)

• Located inside a U.S. military live-fire training range. Live ammunition exercises limit or forbid civilian access.

• Volcanic eruptions repeatedly create and erase land. The island's size and shape change after eruptions, making safe landings unpredictable.

Polar and near-polar rocks and islets

• Janette Island (Arctic), Sturge Island (Antarctica) and similar targets are surrounded by sea ice or open polar ocean. Extreme weather, sea ice and remoteness limit safe landing windows and the types of vessels that can approach.

• Extremely small, exposed rocks with very rare landings. Documented visits occurred only in 1965, 1976 and 1993. That sparse record highlights how difficult it is to effect even a short shore landing.

Judge and Clerk Islets (Southern Ocean)

# What makes a final few meters so hard?

A successful landing depends on the interaction of wave energy, shore composition and human technique. Many of these islands are small exposed rocks with no sheltered landing spots. Even when conditions look calm, swells and currents can make disembarkation dangerous or impossible. In polar regions, moving sea ice and fringing bergs remove options for close approach. On volcanic islands, newly formed or unstable lava surfaces may collapse or change between surveys and attempts.

# Practical summary

• Military exclusions: Farallon de Medinilla and Diego Garcia are off-limits or tightly controlled. Access isn't a matter of seamanship but of permission.

• Extreme exposure: Bishop and Clerk Islets have only a handful of documented landings. Judge and Clerk Islets have no recorded landings in Australian records, which positions them as the most convincing candidate for the world's hardest island to reach.

If your interest is practical — planning a trip, study or an attempt — these examples show that successful access requires the right permissions, carefully timed weather and sea conditions, and in some cases specialized vessels or equipment.
