We rank tours by a Bayesian average of rating and review count, never by which one pays the highest commission and never by opinion alone. A tour with a perfect score on a few reviews should not outrank one with an excellent score on thousands, and the formula below stops that. See how we verify this for the full method.
The score ignores price on purpose, so a cheaper trip can sit lower than a pricier one. Read the price column and the notes before you decide. Every price, rating and review count on this page was read from GetYourGuide's Railay Beach listing on the date shown.

How we rank these tours
A tour is only ranked if it has at least 4.5 stars and 40 reviews, enough that the rating means something. We pooled the twelve shared day trips priced per person. Private charters are priced per group and are covered on the tours page.
The formula
score = (reviews × rating + 20 × 4.5) ÷ (reviews + 20). The 20 is a prior weight: it takes about 20 reviews before a tour's own average counts as much as our 4.5 baseline. Ratings are used as the partner displays them, rounded to one decimal.
