Overview

GMU 422 covers all of Vashon and Maury islands in central Puget Sound, King County — a suburban-rural island unit reachable only by ferry. WDFW manages an overabundant Columbian black-tailed deer herd here with liberal, damage-driven seasons, and by its own account hunting can be quite good where you can get on the ground. There is no elk, bear or cougar hunting; the entire opportunity is blacktail deer. The catch is access: the general season is archery-only and nearly all huntable ground is private agricultural and hobby-farm property, so success is a networking exercise as much as a hunting one.

Terrain

Two low, forested islands joined at Portage — Vashon and Maury — rising from tidewater to only a few hundred feet. Rolling glacial upland dissected by ravines, with tidal flats and marsh along the shore.

Cover: Thick, lush second-growth Douglas-fir, red alder, bigleaf maple and dense salal/blackberry understory, broken by small cleared fields, orchards and hobby farms. Edge cover between woods and pasture concentrates deer.

Landmarks: Portage isthmus (Vashon–Maury connection) · Maury Island Marine Park · Island Center Forest · Point Robinson · Quartermaster Harbor · Burton Peninsula

Access

WDFW rates access as the primary limitation: hunting is mostly on private agricultural and hobby-farm parcels and hunters must invest time networking with landowners and the island community for permission. King County's Island Center Forest may open to public hunting during the modern firearm season (firearm-restricted) — contact King County for details. The general season is archery-only across the unit, and additional opportunity comes through the second deer special-permit category. Use King County iMap and the WDFW Hunt Planner webmap to sort ownership before knocking on doors.

Managers: Private (agricultural / hobby farm), King County Parks, WDNR, Private residential

Access points: Vashon ferry (Fauntleroy/West Seattle, Southworth, and Point Defiance–Tacoma routes) · Island Center Forest trailheads · Maury Island Marine Park · County road network across both islands

Species notes

Blacktail Deer

abundant opportunity

Columbian black-tailed deer are abundant and often overabundant on the islands; WDFW runs liberal, damage-oriented seasons to hold numbers down and reduce vehicle collisions. Prospects are good wherever you can secure ground, but the general hunt is archery-only and access is the whole game.

  • Spend the off-season networking — knock on doors at farms and hobby properties well before opening day; access, not deer, is the limiting factor
  • Hunt the edges where second-growth timber meets pasture, orchards and cleared fields at first and last light
  • Set stands over trails between bedding cover in the ravines and feeding fields
  • Check King County about Island Center Forest opening during the firearm season, and look at the second special-permit category for added opportunity
  • Keep shots and setups well clear of houses, livestock and roads — this is a suburban island

Pro tips

  • Treat landowner relationships as the real trophy — a single farm permission can carry your whole season here
  • Bow only for the general season; sight in and practice for close, brushy shots at field edges
  • Use King County iMap plus WDFW Hunt Planner to identify parcel owners before you ask
  • Ask King County Parks directly whether Island Center Forest opens to the firearm-restricted hunt this year
  • Watch the second deer special-permit category — WDFW keeps adding island opportunity there

Watch out for

  • !General season is ARCHERY-ONLY on Vashon/Maury — modern rifle is not legal for the unit
  • !Nearly all ground is private; hunting without written/verbal permission is trespass in a densely settled community
  • !County no-shooting ordinances and dense residential development sharply limit where discharge is legal
  • !No elk, bear or cougar season here — blacktail deer is the only big-game opportunity
  • !Ferry dependence means weather and schedule disruptions can strand access

Logistics

Everything comes and goes by Washington State Ferry — plan around sailing schedules from Fauntleroy (West Seattle), Southworth (Kitsap) or Point Defiance (Tacoma). There is no camping-in-the-backcountry option; base out of the town of Vashon or day-trip from the mainland. Services (fuel, groceries, lodging) are on-island but limited, so arrive provisioned.

Nearest towns: Vashon, Burton, Dockton, Seattle (via ferry), Tacoma (via ferry)
