We do not have a free trial for our Pro subscription, however, that being said, we do offer a 30 day money-back guarantee for subscriptions purchased on our website. If you are not satisfied with your Pro subscription at any point during the 30 day window, you can contact our team at support@alltrails.com and we'll issue a full refund, no questions asked.
NOTE: In order to be eligible for the money-back guarantee you will need to sign up using a desktop or laptop computer at https://www.alltrails.com/pro/signup, NOT the app.
