Hawaiʻi Island (the Big Island) travel tipsthe general rules
Currency budget United States
ExpensiveCards everywhere, but carry some cash: the entrance booth at a park may be card-only or cash-only depending on the day, and the last petrol station before a park often is too. Tipping is 18–22% wherever somebody serves you.
ATMs & cards
Draw in the last town before the park: machines inside the parks are few, charge heavily, and run out at weekends. Chase, Wells Fargo and the credit-union machines are the cheapest; the ones in petrol stations are the dearest.
Avoid these
- the machines inside the park and at petrol stations, which charge heavily and empty at weekends
Use these instead
- Chase
- Wells Fargo
- any credit union
Draw in the last town before you go in. Decline the conversion.
Wherever you are: if the machine offers to charge you in your home currency, decline. That is dynamic currency conversion and the rate is set by the ATM's operator, not your bank.
Safety all of United States
SafeComfortable. The volcano is monitored and the park closes what needs closing — follow it rather than the internet. Mauna Kea is 4,200 m: altitude sickness is common, the visitor centre asks for half an hour of acclimatisation, and the summit road is unpaved and 4x4 only. Lava fields are sharp and unstable, and the surf on unpatrolled beaches is the usual island hazard.
Where to walk, and where to pay attention (6 areas)
Comfortable, including after dark
Worth more attention
- the Mauna Kea summit road — 4,200 m, unpaved, and 4x4 only under most hire agreements
- lava fields off the marked trail — sharp, unstable and hot underneath
- unpatrolled beaches — the surf here has no lifeguard and no warning
Our own assessment, not a sourced index.
Entry & visa United States visa rules
Travel authorisation requiredup to 90 days$40
ESTA under the Visa Waiver Program. Romania was admitted in 2025 and then suspended again, so Romanian passports currently need a full visa — this one has flipped twice, so check the official link rather than trusting anything written down, including this. Bulgaria and Cyprus have never been in the programme. ESTA is refused if you have travelled to Cuba, Iran, Iraq, North Korea, Sudan, Syria, Libya, Somalia or Yemen since 2011 — those trips mean a full visa instead.
Other passports
No visa neededup to 180 days
Visa required in advance$185
A B1/B2 visitor visa, with an in-person interview. Waiting times run to many months in some countries — start early.
How to get it: Apply for ESTA at esta.cbp.dhs.gov at least 72 hours before travel. Every other site charging for this is a reseller.
Entry rules change often and depend on your passport, not where you live — the official page above is the authority, and the airline checks before you board.
Before you fly: travel authorisation
ESTARequired
At least 72 hours before you fly. Most come back in minutes, some take days.
Have these in front of you before you start:
- passport
- a credit or debit card
- your employer's name and address
- any other citizenships you hold
The page calls itself the "Official ESTA Application Website" in its own title, because the trade in charging for this is large. Valid two years, not per trip.
Use the official link above. Sites that charge a "service fee" to submit one of these for you are not the government, and they want the same passport details the real form does.
Health & emergencies all of United States
LimitedRequired to enter
No vaccinations are required for entry from Europe or North America.
Jabs worth having, and what happens if you need a doctor
Worth having
- Routine vaccinations up to date
Getting treated
The care is excellent and the bill is the risk. There is no universal system, an ambulance ride alone can run into four figures, and an uninsured hospital stay can be genuinely ruinous. Comprehensive travel insurance with a high medical limit is essential — this is the one destination where skipping it can cost more than the trip by an order of magnitude.
Orientation, not medical advice — entry rules change and what you need depends on your own history. Check with a travel clinic four to six weeks before you go.
Food tip
Very goodKona coffee at the farms it comes from; poke, plate lunch and loco moco; malasadas; and the Saturday farmers’ market in Hilo, which is where the island shops.

Time zone and your working day
Pacific/Honolulu — 6 hours behind you

No overlap with a 09:00–17:00 day where you are. Working from here means one of you keeps odd hours — their day starts at 15:00 on your clock.

Internet speedall of United States
Why these are United States's numbers and not Hawaiʻi Island (the Big Island)'s
Home broadband — Fast. Several people on calls at once, large uploads, 4K. Broadband here runs at 2.4× the global median of 130 Mbps.
Mobile data — Fast. Enough to work from a cafe or a beach on a hotspot all day. Mobile runs at 1.7× the global median of 109 Mbps.
Ookla publishes no separate figure for Hawaiʻi Island (the Big Island), so these are medians for all of United States. Cities usually beat the national number and remote islands and national parks fall well below it — treat this as the country's shape, not as a measurement of the street you will be staying on.
A median is the middle of every connection tested there, old copper and new fibre together — so in a country part-way through laying fibre it sits well below what a fibre line actually delivers, and a rental on one can run several times this number. Half of the connections are slower; a fibre flat is rarely one of them. It says what a place can do, not what your rental does, so every listing on Holistay carries its own measured speed and the date it was tested.
Getting online: Airalo or Holafly — a data eSIM for United States, installed before you fly and working the moment you land.

Religion
Christian majority, no state religion
Constitutionally separated from the state, and enormously varied by region — the south is far more observant than the coasts.
Do's and don'ts
Do
- Tip 18-20% at restaurants and bars — servers are paid below minimum wage and depend on it
- Expect sales tax to be added at the till, not shown on the shelf price
- Make small talk with strangers; friendliness is genuine and not a prelude to anything
- Carry ID if you look under about 35 and intend to drink
Don't
- Do not skip the tip to make a point — take it up with the manager instead
- Do not discuss politics, guns or healthcare with strangers unless invited
- Do not stand too close; personal space is larger than in Europe or Latin America
- Do not joke about security at airports or borders
