There are 201 spots in the catalogue with a recommended level of beginner, the field whoever registered filled in looking at the place, not at the map. This page separates the ones with a school at the spot and the ones with sheltered water and no waves, which are the two things that decide the first week.
38 of them have a school registered in the spot's facilities. It is the difference between learning where you ride and learning in one place and riding in another.
46 beginner spots where the community registered sheltered water and no waves. Water that forgives is what makes the difference between falling and getting up and falling and giving up.
It depends on the person and on the wind, and the one who answers that is the school, not a website. What the catalogue can tell you is where to learn: 38 spots have a school registered in their own facilities.
No. Most schools include gear in the lesson, and there are spots with rentals registered. In the app, the rental filter shows who has gear available near where you are going.
Sheltered is water with some protection, such as a reef, an island or a cove, and for that reason it forms no waves. Flat is the smooth surface, which usually comes with it but not always. The catalogue keeps the two states apart, because a spot can be one thing at low tide and another at high tide.
