If your staying in a PM site then either 600, 900, or 1400 would be the best in my opinion. All 3 are close to the pond between the Meadow Trading Post and the Bike Barn where the small dock is that you are allowed to fish from. 1400 is also not far from one of the other fishing locations behind the 300 loop near the spillway into Bay Lake. These two locations along with the pond at Group camping are the only 3 fishing spots you can fish at the Fort.
