Rattlesnake Hills Wine Trail

The Rattlesnake Hills Wine Trail is a driving route through vineyard tasting rooms centered on Zillah, Washington, stretching from Union Gap to Sunnyside Gap in the Yakima Valley. Its wineries sit within the Rattlesnake Hills American Viticultural Area (AVA), a federally recognized grape-growing region contained entirely within the larger Yakima Valley and Columbia Valley AVAs.

The draw here is being close to where the wine gets made. Many tasting rooms stand among estate vineyards, with orchards, rolling hills and, in clear weather, views of Mount Adams and Mount Rainier. Settings range from barn tasting rooms to contemporary buildings and European-inspired architecture. You may find the owner or winemaker pouring—a good opportunity to ask what they grow nearby and what they recommend opening with dinner. Expect Cabernet Sauvignon, Merlot and Syrah alongside whites, blends and less-familiar grape varieties.

How to plan a tasting day

This is countryside wine touring, not a walkable tasting-room district. Use the trail’s online or printed map to group nearby wineries rather than zigzagging across the valley. Plan on three tasting visits in a day, with time for lunch and the drives between them; a fourth makes sense only if your stops are close together and you keep the pace light. Arrange a designated driver before setting out.

Zillah is the natural base for keeping close to the vineyards. Yakima works well if you want a city base near the western end, while Sunnyside is useful for exploring the eastern stretch. From Seattle, allow roughly two and a half hours via Interstate 90 before accounting for traffic, mountain-pass conditions and your final tasting-room destination. An overnight stay makes a more relaxed plan than combining that drive with a full tasting day and a return trip.

When to go and whether to book

Spring through fall weekends are the simplest choice for a first visit, when seasonal tasting-room schedules offer more options. Published hours often fall around 11 a.m.–5 p.m., but opening days differ: some wineries welcome visitors daily during their main season, while others concentrate on weekends. Winter brings reduced schedules and some seasonal closures.

Walk-in tasting is available during published public hours, so you do not need to reserve every visit. Still, some wineries encourage reservations, and weekday visits may require an appointment. Check each planned stop’s current hours, tasting fees and booking guidance before leaving—especially for a group. Leave room in the schedule for a conversation rather than treating the map as a checklist.
