Frequently Asked Questions

Why is reef-safe sunscreen required in Hawaii?

Hawaii has legally banned sunscreens containing oxybenzone and octinoxate since 2021. These chemicals damage coral reefs and marine life. Only mineral sunscreens (zinc oxide or titanium dioxide-based) are permitted. Visitors caught with banned sunscreens can be fined. Buy reef-safe sunscreen before you travel — choice is better and prices are lower than on the islands.

How far is Honolulu from the UK?

About 16–18 hours total flying time, almost always with a connection through Los Angeles, San Francisco, or Seattle. There are no direct flights from the UK to Hawaii. Plan the connection carefully — US customs must be cleared at your first US point of entry, which adds time to the LA or SF connection.

What is the best time to visit Hawaii?

Hawaii is excellent year-round. April–June and September–November are the quietest with the best value on accommodation. December–March is whale season (humpback whales return to the warm Hawaiian waters). Summer (July–August) is family peak season with higher prices. It never gets cold in Honolulu.
