Delaware and Raritan Canal State Park

Other people will be more knowledgeable than I am, but I've parked in a little lot on Quaker Road at 40.3085, -74.6804. The Canal tow trail runs RIGHT by there, and you can do a ten-mile out and back N/NE and only cross three roads. You can also run on the path along Quaker Road into the Institute woods and then into Princeton.

Yes there is the canal path that you can walk or ride your bike. You can go up to high rocks for a more rigorous hike. You have great restaurants in lumberville a winery n golden pheasant restaurant up the road which is delicious! Then frenchtown great stores n restaurants but you should ride a bike n take water! Enjoy !! it's great up here!!

Yes

Yes with license

I have not seen any exercise equipment either.

No - not SAFE

They do stock it with trout in the spring. Otherwise not much.

Griggstown and Princeton both have boat rental servicrs available. You are also allowed to bring your own boat.

In my opinion, it's not a good idea. The water flows through the canal at a pretty good speed. If there is any ice at all, there's a really good chance it's not thick, or stable, enough to support your weigh. There is a really good chance you can fall through and get hurt or even worse, drown. Be safe and check with the park authority before venturing out.
