Espinosa Campground via Vencente Falls

Where is the best place to ask questions about a particular trail?

A little new to All Trails. Wondering if reservations are needed for this campground for one. And Are there multiple places to camp on this trail. Have a new pup and the whole distance at once might be a little much.

Please advise me on where to go in the future for information on specific trails.

Thank You
