Tinian: luminous reef walls, WWII underwater heritage and a slower south-coast island escape
Use this travel brief to set arrival flow, local transit, and gear movement before you lock your itinerary.
Saipan is the practical gateway. Fly into Saipan (SPN) using an available international or domestic connection, then reserve a separate Saipan-Tinian (TIQ) flight with STAR Marianas Air, which publishes scheduled daily services of roughly 15 minutes. Frequencies are published schedules, not guarantees. The airline quotes a standard USD $85 one-way fare, subject to change, and a limited baggage allowance. Rates.
For scuba, a separate route is to stay on Saipan and book a Tinian day-boat dive if the operator actually confirms departure and weather. Fishguyz advertises a Tinian two-dive outing; this does not establish passenger transfers, arrival on Tinian, or an overnight-based Tinian operation. No regularly scheduled public passenger ferry could be verified; occasional festival boats are not a standing service. . Never rely on sea transport without receiving a current boarding point, landing permission, fare and return confirmation.
Tinian International Airport / Francisco Manglona Borja Airport
TIQ • PGWT
Tinian's inter-island airport served by the published STAR Marianas Air Saipan service; independent check-in and surface transport must be arranged. No regularly verified through-checked dive-gear service.
Transport: Pre-arranged island rental car pickup if available, Accommodation transfer only if explicitly arranged
Saipan International Airport / Francisco C. Ada International Airport
SPN • PGSN
Main onward connection point, not Tinian itself. Travelers continue by a separately booked Saipan-to-Tinian flight or join an actual confirmed Tinian scuba excursion that returns to Saipan.
Transport: STAR Marianas Air inter-island scheduled flight to TIQ, Confirmed Saipan-based scuba day-boat for divers only; not a ferry
The most flexible Tinian plan is advance-arranged car rental or a confirmed local pickup, not a guessed frequent taxi or bus. Islander Rent-a-Car advertises a Tinian location, but live fleet availability is not established. Distinguish clearly public San Jose, Taga, Tachogna and Jones Beach areas from military-leased northern parcels. DCRM requires prior permission and guided access for listed military-area shore sites; road access is not evidence of visitor authorization. Avoid driving off-road or along unverified roads because of UXO and access controls.
Tinian is in the U.S. Commonwealth of the Northern Mariana Islands. Entry depends on citizenship, passport, point of origin and immigration category, not merely on booking a Tinian flight. U.S. citizens follow applicable U.S. ID/passport rules for their itinerary. For eligible non-U.S. visitors, check the official Guam-CNMI electronic travel authorization portal for the relevant visa-waiver option or ESTA for the regular U.S. Visa Waiver Program; other visitors may need a U.S. visa. MVA describes these as distinct pathways; do not confuse their limits or assume eligibility.
Time-sensitive rule (announced 27 October 2026): A Federal Register notice suspends the separate CNMI EVS-TAP for People's Republic of China nationals starting 30 October 2026 at 14:00 EDT, including previously approved travel authorizations for future admission. Affected travelers generally need an appropriate visa unless another lawful exception applies. Old paper-based or PRC-specific waiver instructions are not reliable. Verify current CBP rules and carrier document checks before buying nonrefundable travel. Complete any required customs declaration.
Scuba travelers should ask the operator exactly which tanks, weights, computer, wetsuit and safety gear are included; Fishguyz's posted tariff lists equipment rental separately (USD $40 per day as advertised), without proving availability today. If flying on STAR Marianas Air, its advertised 20 lb baggage and 10 lb personal item allowances can constrain packed scuba kits; check airline size limits and excess-baggage arrangements before flying. No Tinian dive-fill station, equipment-rental counter, gas blend or freedive instruction center has been independently verified. Bring basic mask/snorkel gear if your trip depends on it. No scuba before flying without an appropriate DAN surface interval.
United States Dollar (USD)
U.S. dollars are the local currency. Bring small bills for modest island purchases and confirm card acceptance at lodging, car rental and tours before arrival. Transport and dive rates quoted in this guide are publisher-advertised examples, not live prices.
A reliable, currently operating Tinian ATM network or cash-withdrawal limit has not been verified. Do not depend on finding a working machine after landing; obtain sufficient cash in advance and protect emergency funds.
110-120V nominal • 60Hz • A, B
U.S.-style flat-pin power is standard in the CNMI. Travelers with other plug types should bring a compatible adapter and confirm that their charger supports the local nominal voltage.
Communications
English is suitable for most visitor arrangements; coverage can be patchy outside San Jose and in remote shoreline areas. The DCRM shore guide specifically warns of no cellular reception at certain northern beaches, which are not unrestricted visitor sites. Verify roaming or a local mobile plan in advance, download offline maps and keep an emergency contact and return plan. Do not assume a boat excursion provides mobile data offshore.
Language
English is widely used for visitor logistics; Chamorro and Carolinian languages and cultural heritage are integral to the Northern Mariana Islands. Use local place names respectfully and ask permission before photographing people or culturally sensitive spaces.
Insurance
Choose travel cover that explicitly includes your planned scuba depth and activities, diving-related medical expenses, emergency evacuation and recompression where available. Standard travel policies may exclude cavern, technical or unsupervised freediving. Confirm flight interruption and nonrefundable boat deposit cover for weather cancellations, and check DAN guidance for dive-medical help. Neither the operator's posted sales page nor a local health center listing proves insurance or chamber access.
Packing list
Bring reef-safe sun protection, a rash guard, sturdy sandals and walking shoes, water, a light rain layer, mask/snorkel if needed, personal medicines and an offline itinerary. Boat divers should check gear and weights directly with the operator. Small-plane travelers must account for STAR Marianas Air's limited baggage allowances. Respect cultural sites, take out litter, keep clear of explosive remnants, and carry no collecting tools for WWII artifacts.
