Tips for Sustainable and Respectful O‘ahu Travel

Oʻahu’s beauty runs far deeper than its beaches and palm trees. As you explore the island, a few mindful choices can make your visit more meaningful and sustainable. From practicing ocean safety during powerful winter swells to showing respect for local customs and sacred places, every small action helps protect Hawaiʻi nature and cultural heritage. Here are some essential tips to travel responsibly and mālama (care for) Oʻahu while you’re here.

Ocean Safety

Be advised: Winter is when Oʻahu’s North Shore sees massive swells. This is not the time of year for amateur surfing, or swimming, on that side of the island. Stick to the South Shore for the calmest waters in the winter. Powerful shore breaks, high surf, strong currents and rip tides are common. Since ocean conditions can change at any moment it is important to always proceed with caution. Where possible, swim at lifeguarded beaches and never turn your back on the ocean. “If in doubt, don’t go out!”

Read the signs

Lifeguards will post beach warning signs to inform beachgoers of any hazardous conditions. These signs will give you any number of cautions, including unsafe swimming conditions and high surf advisories. These are here to keep you safe. You must obey these signs.

Box Jellyfish

Once a month, 9-10 days after the full moon, South Shore and Leeward beaches are visited by box jellyfish. These jellyfish sting and can lead to severe injury and scarring. If you get stung, find a lifeguard or seek medical attention. Waikīkī Aquariumʻs Box Jellyfish Calendar will tell you when these jellyfish are likely to be in the water.

Safe Beach Day posts current weather, surf and beach conditions for all Hawaiʻi beaches.

From Hawaiʻi Travel Authority: Hawaiʻi's ocean and beach conditions are as unique as the islands themselves. Visit HIOCEANSAFETY.COM which constantly monitors the surf, wind, and reports from public safety officials that directly affect the conditions for safety of Hawaiian beaches. Use the hazard signs on HIOCEANSAFETY.COM as well to quickly assess conditions and help you find the appropriate beach for your visit.

1. Walk, bike or bus - Oʻahu’s bus system is one of the best in the country. Use a map app on your smart phone for directions, select “transit” and follow the instructions for when and where to catch the bus. You can also use the DaBus2 app for routes and schedules. $3 for adults. If you are between Chinatown and Waikīkī, you can use BIKI, Oʻahu’s bikeshare program. BIKI stations are everywhere and its an affordable way to get around. $5 for 30 minutes or $20 for the day for visitors.

2. Stay at a LEED certified hotel - Sheraton Waikīkī Beach Resort, Westin Moana Surfrider and the Royal Hawaiian Hotel are all LEED certified.

3. Participate in a plastic-free Hawaiʻi - Pack a re-usable water bottle, minimize use of single-use plastics like to-go containers, participate in a beach clean-up, watch “A Plastic Ocean.”

4. Clean up after yourself - Please help us keep our beaches, parks and all public spaces clean. Throw away your litter and take everything you bring home with you.

5. Help protect wildlife - Stick to designated trails when hiking. Use reef-safe sunscreen and avoid touching the reef when you are in the ocean. Never touch a sea turtle or monk seal, it is against the law.

6. Eat & Shop local - Look for local brands and businesses to support. Shop at farmers markets and mom-and-pop spots rather than chains and big box stores.

Most visitors were not taught about Hawaiian history in school. All we know is what we see in the media. It is important for everyone who wants to visit Hawaiʻi to learn the history of these islands and how tourism became one of their main economic drivers. This will not only inform your decisions and choices when you are here, but also give you a new perspective and appreciation of Hawaiʻi and Native Hawaiians.

To learn about Hawaiian history during your trip to Oʻahu, including the illegal overthrow of the Kingdom of Hawaiʻi on January 17, 1893, take a tour of ʻIolani Palace, visit Bishop Museum and participate in cultural activities offered by around the island and by your hotel.

Tips for Respectful Travel to Hawai‘i

• Learn about the history of Hawai‘i – Understanding the islands’ complex past — including colonization by the U.S. and the ongoing Hawaiian sovereignty movement — adds depth to your visit and acknowledges the people.

• Respect sacred sites – Cultural and spiritual sites are not tourist attractions — they’re places of deep significance. Avoid disturbing these areas, and never take sand or lava rocks home.

• Dress conservatively when necessary – Avoid wearing shorts or revealing clothing inside cultural sites, and save swimsuits and bikinis for the beach.

• Learn a few Hawaiian phrases – Simple greetings like “aloha” (hello/love) or “mahalo” (thank you) go a long way.

• Engage with the culture and community – Attend local festivals, hula performances and other cultural events, and take the time to connect with residents — respectful conversations can offer meaningful insight into Hawaiian life and values.

• Support local businesses – Shop at markets, eat at family-owned restaurants and choose Hawaiian-led tours to directly support the economy.

• Practice responsible tourism – Leave no trace, stay on designated trails, avoid disturbing wildlife and be mindful of resource use. Protecting Hawai‘i’s fragile ecosystems is essential to preserving its beauty and biodiversity.

• Be respectful of customs and traditions — Follow local etiquette and approach your visit with humility and a willingness to learn. An interest in their complicated past is a great start!
