Prosser
Skip unless you are a wine lover or passing I-82 between Yakima and Tri-Cities: one afternoon for tasting rooms and Gravity Hill.
Prosser is a small agricultural town on the Yakima River, best known as the heart of Washington's Horse Heaven Hills wine region. Most visitors stop for a few hours to visit tasting rooms, see the quirky Gravity Hill, or attend the September Balloon Rally. It is not a base.

Etiquette, safety and scams
Etiquette
- Greeting: Handshake and 'hi, how are you?' — reply 'good, thanks'; avoid: Treating the question as a real health enquiry
- Restaurants: Tip 18–22% and wait for the check; avoid: Leaving without tipping
- Personal space: Keep an arm's length in queues; avoid: Standing close to strangers
- Politics and religion: Listen more than you speak; avoid: Opening with hot-button topics
- Smoking: Smoke only in marked areas; avoid: Smoking near doors or in parks where banned
Scams and watch-outs
- Tasting rooms often close by 5–6 PM; check hours ahead, especially in winter.
- Gravity Hill is about 10 miles north on a gravel road; a standard car is fine, but avoid after rain.
- No Uber or Lyft reliably available; plan for a designated driver or taxi from Tri-Cities.
Very safe. The main risk is driving after tasting; plan a designated driver or use a hired car from Tri-Cities.
