Mukilteo-Clinton Ferry 20-Minute Crossing: How to Read WSF Schedules
Save time and headaches: the Mukilteo–Clinton ferry is a 20-minute hop, here’s how to read WSF times, vessel assignments (Kitsap, Tokitae) and planned construction interruptions.
1. why the Mukilteo–Clinton crossing matters
The Mukilteo–Clinton ferry is the primary route to and from Whidbey Island for many Island County residents and visitors and “this quick hop connects the northern Seattle suburb of Mukilteo with tiny Clinton on the southern tip of Whidbey Island.” The crossing takes 20 minutes, making it the fastest vehicle link off the island and a frequent commuter corridor; the driving alternative via the Deception Pass Bridge takes about 90 minutes longer from metro Seattle. Because WSF maintains multiple sailings and vessel rotations each day, reading the timetable correctly can save you wait time, missed connections and stress on busy Fridays and holiday weekends.
- Duration: 20 minutes per crossing.
- Typical service span: practical guidance notes “Service generally begins shortly after 5 am and runs until 1 am,” though the official timetable includes earlier and later sailings in certain seasons.
- Boats and capacity: “Typically, two boats serve the route, except very early in the day or very late,” with vessel capacity “depending upon the boat, it can carry between 120 and 140 vehicles” and boats that “can accommodate everything up to large semi-trucks.”
- Named vessels shown on local tables: Kitsap ♿ and Tokitae ♿ (wheelchair symbol shown beside the names). These quick facts are the foundation you should check against the live WSF schedule when planning travel.

3. official schedule snapshot you can read right now
WSDOT provides the authoritative schedule blocks for this route; the excerpted season block included in available materials is labeled “Dec 28, 2025 - Mar 21, 2026.” Below are the exact lines from that WSDOT excerpt so you can see how times and day notes look on the official printout.
Leave Mukilteo (Daily) 5:05 1 Mondays through Fridays only | Noon 1 | 7:05 1 5:35 2 Mondays through Fridays only | 12:30 2 | 7:35 2 6:00 1 | 1:00 1 | 8:05 1 6:30 2 Mondays through Fridays only | 1:30 2 | 8:35 2 7:00 1 | 2:05 1 | 9:00 1 7:30 2 Mondays through Fridays only | 2:35 2 | 9:30 2 Saturdays and Sundays only 8:00 1 | 3:05 1 | 10:00 1 8:30 2 | 3:35 2 | 10:30 2 Saturdays only. 9:00 1 | 4:05 1 | 11:00 1 9:30 2 | 4:40 2 | 12:05 1 10:00 1 | 5:10 1 | 1:05 1 10:30 2 | 5:40 2 | 11:00 1 | 6:10 1 | 11:30 2 | 6:40 2 |

Local schedule table (Clinton → Mukilteo) published by a Whidbey Islands source shows these departures and vessel assignments: 4:40 AM | Kitsap ♿ 5:05 AM | Tokitae ♿ 5:30 AM | Kitsap ♿ 6:00 AM | Tokitae ♿ 6:30 AM | Kitsap ♿ 7:00 AM | Tokitae ♿ 7:30 AM | Kitsap ♿ 8:00 AM | Tokitae ♿ 8:30 AM | Kitsap ♿ 9:00 AM | Tokitae ♿ 9:30 AM | Kitsap ♿ 10:00 AM | Tokitae ♿ 10:30 AM | Kitsap ♿ 11:00 AM | Tokitae ♿ 11:30 AM | Kitsap ♿ 12:00 PM | Tokitae ♿ 12:30 PM | Kitsap ♿ 1:00 PM | Tokitae ♿ 1:30 PM | Kitsap ♿
4. how to read WSF times and footnotes (step-by-step)
1. Start with the schedule block date range printed at the top of a WSDOT timetable (for example, the excerpt shows “Dec 28, 2025 - Mar 21, 2026”). That tells you which seasonal rotation applies.
2. Note time entries with small numbers or markers next to them (the excerpt appends “1” and “2” to many times). Those are footnote indicators and can change whether a sailing runs on weekdays only, weekends only or under specific conditions. The excerpt itself shows examples like “5:05 1 Mondays through Fridays only” and “7:30 2 … Saturdays and Sundays only.”
3. Check day‑specific text on each row: many times will include explicit notes such as “Mondays through Fridays only,” “Saturdays only,” or “Saturdays and Sundays only.” Treat those as binding for your travel date.
4. Match vessel names where provided. Local timetables may show vessel assignments (for example, Kitsap ♿ and Tokitae ♿ for specific Clinton departures); assignments matter for capacity and accessibility. If a time has no vessel listed on the published excerpt, expect WSF to assign a boat that day and confirm the vessel and boarding rules via WSF real-time updates.
5. Mukilteo terminal: approach, holding lanes, payment and busiest times
If you’re a first-time rider, “you follow S.R. 525 into Mukilteo and to the entrance to the ferry terminal.” When the holding area fills, “there is a lane on the right-hand side that is used”, if you see other cars in that line, get in behind them. Fridays, especially “going in to three-day weekends, are particularly prone to backing up,” so allow extra time and consider an earlier sailing. At the ticket booth “you can pay via cash or credit card. There is a charge for the car/drive and any additional passengers,” so have payment ready and expect the normal vehicle-plus-passenger fee structure (no dollar amounts were provided in the materials).
6. reservations, vehicle rules and inter‑island caveats
“Reservations are highly advised for vehicles (necessary for travel both to and from the islands),” and online reservations for island travel are released in tiers: “two months before the start of the season, two weeks before the date of sailing, and two days before the date of sailing.” That tiered release applies to online reservation inventory; if you regularly drive onto the island you should plan ahead and watch the release windows. Note that some policy lines in visitor guidance apply specifically to inter‑island crossings: “For inter-island ferry crossings, walk-on passengers ride free in either direction, while vehicles are charged a fee only for westbound crossings. Inter-island ferries accept cars and passengers on a first-come basis.” Do not assume every sentence about inter‑island practice applies to Mukilteo–Clinton; treat the WSDOT/WSF timetable and reservation pages as definitive for vehicle reservations on this route.
7. construction impacts, planned suspensions and night‑work cancellations
Local notices include a construction advisory: “Reminder – Construction will affect our Mukilteo/Clinton route in early 2026. We will suspend service for four hours midday on these weekday dates:”, Tuesday, Feb. 3; Wednesday, Feb. 4; Friday, Feb. 6; and Monday, Feb. 9. On those weekday dates the last morning sailings will be “8:30 a.m. out of Clinton” and “9:00 a.m. out of Mukilteo,” with service resuming as the 1:00 p.m. Clinton departure and the 1:30 p.m. Mukilteo departure. Additional night‑work cancellations were flagged: “On the nights of Jan. 30 and Feb. 16-20, the route’s final roundtrip will be canceled. The last sailings will be the 11:30 p.m. from Clinton and the 12:15 a.m. from Mukilteo, 10 minutes later than normal.” These exact dates and altered times were published in local advisories; if you rely on late‑night or midday sailings during maintenance windows, check the official WSDOT/WSF service notices for any updates.
8. while you wait: nearby attractions and food
If you have time between sailings, the Mukilteo terminal sits “just steps from” Ivar’s Mukilteo Landing and is minutes from the Boeing Future of Flight and the Flying Heritage & Combat Armor Museum, useful options for visitors or off‑peak waits. On the Clinton side, consider the Shrimp Shack at Cozy’s for a quick bite near the terminal. If you’re linking onward via Coupeville or Port Townsend, local favorites called out in visitor guidance include Callen’s at Coupeville and Quench Waterfront Kitchen in Port Townsend; the village of Coupeville is noted as about 10 minutes north of the Coupeville terminal for additional shops and eateries.
- Confirm the WSDOT/WSF timetable block for your travel date and check any footnote definitions before you leave.
- Book a vehicle reservation during the release windows when possible: two months, two weeks or two days before sailing according to the reservation‑release tiers.
- Arrive early on Fridays and holiday eves; use the right-hand holding lane at the Mukilteo approach if the holding area is full.
- Watch for construction windows and night‑work cancellations that alter last sailings or suspend mid-day service on specific dates.
9. final checklist before you go
WSDOT/WSF is the official schedule authority for Mukilteo–Clinton operations; use their live schedule and real-time updates to confirm the specific sailings you plan to use. Follow the timetable reading steps above, keep payment and reservations ready, and use nearby dining or museums to turn waiting time into a productive pause.
