It's probably better for newbies not to ride there at all until they have been riding for a year or so. They should have a good idea (based on a few bad experiences at safer spots) of what risks they are taking by doing so (boats, hazards, bridge, trees, etc).

Just my opinion, not trying to preach safety or anything... but big beach is where riders still learning should be riding in a west. It's big, it's safe, and there are no swimmers to deal with.
