I had a great time fishing for trout at Montauk. It is another of the many natural gems and a highlight in a 3 day trip where we enjoyed rivers, springs, shut-ins, small mountains, waterfalls and huge areas of national forest.
The only cost was a daily fishing license with trout tag. We caught 7 Rainbow trout in about 2 hours. Taught a 1st timer how to catch trout and she is hooked on it. The lodge fishing supply store provided great assistance in understanding what bait was meeting with success.
