There are a couple of us on the forum living here.
The riding is great, the council have just installed a number of community hubs with bike wash/tool stations to try and encourage parking away from residential areas.
There are a few rental companies in town. Flying spirit, Biking in Squamish and squamish adventure co.
Trails are well signed and trail forks is pretty well up to date. Don’t forget to donate to SORCA!
Squamish is best as creating a journey through the trails rather than hitting single feature trails imo.
Its turned into a destination in its own right and getting busier every year and loosing some of its small town and ‘undiscovered charm’ but I’ve lived here 11 years now, and certainly wouldn’t move anywhere else.
