Climbing gym advisor is a collection of systematically organized climbing gym info and reviews. It should help climbers to identify an appropriate climbing gym for their level of climbing/preferences. Based on the predefined categories (characteristics of the climbing wall and routesetting, gym facilities, training area, food, etc), one can easily filter out gyms with facilities of interest (MoonBoard, weightlifting area, etc.).
In addition, climbers can vote an individual gym for good route-setting, good vibe, good training area, etc.
C4C team has been collecting info about climbing gyms since 2018.
