Hidden Beaches on Big Island

Remote and Uncrowded

Checking live advisories…
If It Looks Brown, Donʻt Swim
Never enter the ocean when the water appears brown or murky, even if no advisory is posted. Hawaii is often slow to test beaches and update advisories — not every beach is monitored. After heavy rain, wait at least 72 hours and until the water clears before swimming.

Question 1

What are the hidden beaches on the Big Island?

Makalawena Beach (15 min hike), Kiholo Bay (short hike), Green Sand Beach (Papakolea, long hike), Pololu Valley Beach (steep hike), and Waipio Valley Beach are among the most secluded options.

Question 2

Is Makalawena Beach worth the hike?

Makalawena is often called the best beach on the Big Island. The 15-minute hike over lava rock keeps crowds away. The white sand is pristine with low bacteria risk and the Kohala Coast location means consistently clean water.

Question 3

Are remote Big Island beaches safe to visit?

Remote beaches on the Big Island often have no lifeguards, limited or no cell service, and can have strong currents. Always check conditions, bring water and sun protection, tell someone your plans, and never swim alone.

⚠️ The 72-Hour Rain Rule

The Hawaii Department of Health recommends staying out of the ocean for at least 72 hours after heavy rain, even if the water looks clear. Bacteria and pollutants from runoff can linger in the water longer than the brown color does.

⚠️ Important Disclaimer

Safe to Swim Hawaii is an independent passion project — it is not affiliated with the Hawaii Department of Health, Big Island beaches, or any government agency or hotel brand. Water quality ratings on this site are estimates based on publicly available testing data and geographic analysis. They are not real-time measurements and may not reflect current conditions. “No DOH Alerts” means no advisory is currently posted — it does not mean the water was tested and found safe. DOH only monitors a fraction of Hawaii’s beaches, and some areas have no regular testing at all.

Always verify current water quality conditions with the Hawaii Department of Health Clean Water Branch before entering the water. This site is for informational purposes only and should not be the sole basis for any swimming decisions.

This site is a work in progress and we want to make it better. If you notice something that isn’t working right, have a suggestion, or want to share local knowledge about a beach, please reach out.

When in doubt, don’t go out. 🤙
