Use this travel brief to set arrival flow, local transit, and gear movement before you lock your itinerary.
Arrive by road via Washington US-101 on the west side of Hood Canal. Hoodsport is the southern dive logistics base, Mike's Beach and Hama Hama are on the Lilliwaup stretch, and Brinnon is farther north for Triton Cove and Dosewallips. Seattle-Tacoma International Airport (SEA) is a practical large commercial airport; arrange a rental car or driver. From greater Seattle, routes may go south via Tacoma/Olympia or use an optional Washington State Ferry plus roads and the Hood Canal Bridge. The ferry is not a scheduled dive-site transfer. Road, bridge, weather and ferry conditions can affect travel. No destination-wide water taxi or overnight dive vessel supply is verified.
Seattle-Tacoma International Airport
SEA • KSEA
Varies with the selected Hoodsport, Lilliwaup or Brinnon base and chosen route • Allow a multi-hour road journey; verify route and traffic rather than relying on a fixed advertised time
Major commercial gateway for western Washington; onward access to the west-side Hood Canal shore diving circuit is by road, not a scheduled dive boat.
Transport: Rental car suited to wet dive gear, Pre-arranged private road transfer
A car is the most practical way to move among Hoodsport, Lilliwaup and Brinnon with tanks and drysuits. There is no verified frequent local shuttle network connecting all shore entries. Private resort beaches have designated parking and check-in; do not use informal road pullouts as a right of way. At state parks, check daylight hours, whether the access is day-use only, and parking/pass rules. Triton Cove hours; Sund Rock parking.
Hood Canal is within Washington state; no regional dive-tourism visa, tourism levy or marine-park arrival tag was verified. Domestic US travelers follow normal identification and road rules. International visitors must independently satisfy US entry requirements, with passport and visa or eligible Visa Waiver Program authorization where applicable. An approved ESTA does not guarantee admission. US CBP ESTA guidance. For land access to private dive properties, however, the reservation or day pass is a separate local requirement.
YSS Dive advertises scuba rental, training, guided diving and local services. Glen Ayr publishes fill discounts through YSS and private gear drying/storage arrangements, while Mike's Beach advertises tank fills. Verify refill hours, equipment size, drysuit orientation, cylinder testing and gas availability with the business before arrival. A private shore access fee is not a rental package.

United States Dollar (USD)
US dollars are used. Private site admission, park passes, lodging, tanks and guiding can be separately charged. Cards are widely used for reservations, but ask small businesses about on-site payment terms and carry some cash for incidental needs.
Do not assume a cash machine at a remote beach or campground. Plan cash withdrawal in a larger town such as Shelton before driving to more isolated stretches of US-101.
120V • 60Hz • A, B
Standard US wall sockets. International travelers may need a plug adapter and a charger rated for 120V. Protect electronics and chargers from rain and salt spray.
Communications
US mobile networks cover inhabited US-101 areas unevenly; do not rely on signal at every cove, forest route or inlet. Download maps and tide data, share a return plan and keep an offline copy of emergency contacts. Resort Wi-Fi availability should be confirmed with the lodging property.
Language
English is the primary language for local operators, park signs and emergency services. Confirm other language needs directly with the chosen instructor.
Insurance
Review health coverage, evacuation assistance, dive accident benefits, cold-water scuba activities and any depths or specialty training exclusions. Ask whether guided versus independent shore diving and technical/overhead activities are covered. DAN offers emergency diving-medicine assistance; membership and coverage terms must be checked rather than presumed. DAN emergency service.
Packing list
Bring a well-insulated exposure suit suitable for cold salt water, hood, gloves and boots; dry clothes and a warm post-dive layer; robust fins for gravel/rock; spare mask; dive light; appropriate SMB and navigation tools; current certification and proof of any training; trail rain gear; and storage for wet equipment. Avoid overpacking for tropical snorkeling. Carry footwear for sharp shell beds and a flexible itinerary if autumn rain or park restrictions change plans.
