About this tour

Trade Seattle’s streets for a downhill ride through the Cascade Mountains on this Seattle Snoqualmie Tunnel Scenic Bike Tour. After pickup in downtown Seattle, travel to Snoqualmie Pass, where your guide fits you with a mountain bike and safety gear and provides water and snacks for the trail.

How this score is calculated

This tour scores 5.00 on Viator (GetYourGuide shows no usable rating). Ratings on these sites cluster near the top of the 5-star scale, so we compare each one with all other ratings on the same site before combining them.

How the score works and rating distribution in Seattle
  • Each provider rating is turned into a percentile: the share of that provider's ratings it beats, weighted by review counts.
  • Listings on different providers are combined in proportion to their review counts.
  • Tours with few reviews are pulled toward the average until more reviews come in, so a handful of perfect reviews can't top the list.
  • The result is shown from 0 to 10: this tour scores 7.6. Top 21% in Seattle means it ranks in the top 21% of tours in Seattle by this score.
