We got 25Mbs down with Verizon.

Not great. We have a cell booster that helps. Enjoy this park and campground, it is beautiful. Of course the beach is beautiful but I also enjoyed the hiking trail.

It comes and goes...better near the beach.

It's decent; we were usually at 2 bars on AT

The "cell phone coverage" section on Campendium, just above the reviews, provides information about coverage on various carriers.

It's pretty good. I was able to do everthing I needed on my TMobile/Sprint phone hot spot. Video calls were ok even, but I kept the video off to save bandwidth. The sites closest to the bay seem to have better reception than the ones nearer the beach.
