hmmm...I don't think there are any "water view" sites available anywhere on the island. maybe...but I don't think so. I've only been up w/ the camper once, a couple of years ago. Stayed at "Hadley's Point". It was nice enough...but the full hookup sites were all in an open pull-through type area. not much for privacy. While we were touring the island, we pulled into a few campgrounds, just to check 'em out for future visits...they all seemed pretty much the same, in that regard. "full hookups=open field". But Hadley's was nice, otherwise....also fairly close to the park entrance.
Your question prompted me to poke around, and I found that "Bass Harbor Campground" (www.bassharbor.com
) has free wi-fi.
not particularly close to the entrance to the park, though. but it is a beautiful area. Heck, the whole island is a beautiful area.
