NAHA RIVER NATIONAL RECREATION TRAIL

ACCESS IS BY BOAT OR FLOATPLANE TO NAHA BAY, 23 MILES FROM KETCHIKAN, 12 MILES FROM

KNUDSEN COVE. THE TRAIL STARTS AT THE HEAD OF NAHA BAY FROM THE FLOATING DOCK AND

ENDS AT THE CABIN SITE AT THE OUTLET OF HECKMAN LAKE. BE AWARE OF THE TIDE RACE OR SALT

CHUCK AT THE OUTLET OF ROOSEVELT LAGOON. THIS NARROW, ROCKY CONSTRICTION BECOMES A

FROTHY, ROARING WHITEWATER CHUTE AS THE TIDE COMES IN OR GOES OUT. WHILE A SMALL BOAT

COULD NEGOTIATE THE PASSAGE AT A HIGH, SLACK TIDE, IT IS WISER TO AVOID THIS POTENTIALLY

DANGEROUS AREA AND MOOR YOUR BOAT AT THE FLOAT NEARBY.
