We didn't hike around the entire lake. I think the path is about 3 miles (you should check that). If so, you could probably do this in roughly an hour. The 1/4 to 1/3 of it that we hiked was quite flat. Hopefully someone else who did hike the whole loop can provide you with a better answer, but that's what I can offer.

No you cannot. You can walk about halfway around if you go to the right. But there is a small wood bridge that you cross, and at that point, things get hairy. We did not anticipate how difficult the path became. We climbed out on rock ledges and did alot of walking on two boards nailed side by side. It isn't particularly "difficult." It's only difficult if you anticipated an easy stroll.

No, it is a walking path only.

Without having the map in front of me the easier portion of the trail starts off to the , if you are looking at the pond from the restaurant, to the left of the restaurant. As you wrap around the other side is where the trail gets rockier. Hope this helps!

I am not a bird watcher so I don't know about loons. I had no problem with flies. I was there before Memorial Day. I've heard they are closer to the coastline and in the summer along the coastline.

Don't think there is any kayaking there

I would call about reservations. It almost felt like a club atmosphere and the prices were more than what I would normally pay. A cup of seafood chowder was $11.50.
