There are several low bridges to go under that add some interesting texture to the trip. With a recreational type of kayak, you could easily spend 5 hours round trip. There arent any rocks for fiberglass boaters to worry about except for a few bricks at the put in site.
At one end of the lake, there is a very classy golf course and at the other end you can see The city of Asbury park which is quickly becoming the mecca that it used to be back in the day.
High rise apartments in Asbury, an ocean breeze and the flume (no danger here) which connects the lake to the ocean adds a very different feel from your usual lake type kayak adventure.
On most trips to Deal Lake, I see loads of waterfowl: cormorants, canadian geese, ducks, Egrets, Herons and Brant. There are turtles, and lots of huge carp that throw a wake at your yak as they scoot away from you.
You will have to carry your kayak about a 75 feet to put in. So if you have wheels or a buddy, it helps. The put in itself is not terrific, but I prefer it here to the actual lake launch ramp in the Town of Asbury.
