Absolutely. Sayulita is unique and totally worth visiting. Sayulita restaurants alone make it well worth a visit, even if only for a few days.
In terms of things to do in Mexico, Sayulita has it all: good weather, beaches and interesting culture. Plus (fortunately), it’s not quite as busy as other locations on the West coast of Mexico such as Cancun or Tulum, which means it’s still considered a bit of a hidden gem.
