Use this travel brief to set arrival flow, local transit, and gear movement before you lock your itinerary.
Fly to Seattle-Tacoma International Airport (SEA), then base in Seattle, Des Moines or Tacoma. A car is convenient for carrying gear between shore entries; local buses and rail serve urban centers rather than every beach. The exact visitor circuit needs no overnight boat, cross-border transfer or outer-island connection.
Seattle-Tacoma International Airport
SEA • KSEA
Airport sits between the Seattle and Tacoma visitor bases; driving distance varies by selected shore entry • Variable by traffic, chosen base and amount of equipment
The main passenger air gateway for Seattle, Des Moines and Tacoma. Sound Transit connects its SeaTac/Airport light-rail station to downtown Seattle.
Transport: Link light rail to central Seattle and onward road transit, Rental car for shore site touring, Taxi or rideshare, Regional bus and train connections toward Tacoma
Sound Transit runs Link 1 Line through Seattle and SEA toward Federal Way, and Tacoma T Line circulates downtown Tacoma. Neither reaches all dive entries. Driving is typically easiest for wet gear and cylinders, but Seattle's Water Taxi is a useful Seacrest passenger link. Seattle Dive Tours does not offer customer transportation. Des Moines' Redondo city lot has card-only pay-as-you-exit gates, is open 5am-10pm and forbids overnight parking. Do not assume overnight diver access at park beaches.
The destination is in the United States. U.S. domestic travelers use their normal ID requirements; international tourists must review nationality and entry-purpose rules. The U.S. Department of State describes Visa Waiver Program and ESTA eligibility for qualifying visitors, and visitor visas for others. Diving certifications and marine park rules are separate from permission to enter the country.
Seattle Dive Tours offers a guided two-tank package including cold-water wetsuit and equipment, subject to participant eligibility. Underwater Sports Seattle and Tacoma-Lakewood supply classes, gear work and gas fills. Confirm cold-water regulator capability, thermal sizing, drysuit orientation, gas/air/nitrox availability, cylinder rental and refill hours. Bring wet storage for surface intervals; verify airline rules for dive gear, batteries and cylinders.
United States Dollar (USD)
USD is legal tender; card payments are common. Redondo city lot accepts cards, not cash. Inquire about guide prices, taxes, deposits and specialist equipment costs.
ATMs are accessible in Seattle, Des Moines and Tacoma urban areas. Do not rely on cash for gated municipal parking.
120V • 60Hz • A, B
Standard North American electrical supply; check dual-voltage chargers and adapters for imported cameras and lights.
Communications
U.S. cellular coverage and urban Wi-Fi are generally available, but steep shoreline access and bad weather can affect communication. Store park signs, NOAA tide/current sites, weather updates and emergency contact numbers offline. Marine VHF is a key emergency tool when using a boat.
Language
English is the principal language for official park signs, medical services and scuba training. Ask operators about other-language instruction rather than assuming it is available.
Insurance
Check that medical, travel and adventure cover includes cold-water scuba, the depth/certification level planned, decompression illness and any emergency transport. Some local healthcare can be costly, especially for visitors without U.S. coverage. DAN provides dive-medical advice; insurance benefits and exclusions depend on the exact policy.
Packing list
Pack rainproof outer layers, warm socks, sturdy wet-rock shoes and cold-weather city layers. For diving, confirm a tested cold-water regulator, drysuit thermal undergarments or thick operator-supplied wetsuit, hood, gloves, lights, compass and flag plan. A dry bag, warm drink and spare surface layers are useful between dives.
