This this little gem overlooks Fort Ticonderoga and the scenic bend in Lake Champlain. The British hauled cannon up here, forcing the Americans to abandon the captured fort without firing a shot. The road up starts right in the town of Ticonderoga. The road is not in great shape and the lot at the top is dirt, but it is worth it! Great views.
Mount Defiance is included in a Fort Ticonderoga admission (get a token.) By itself, the toll is $10.
