Narrative: I was flying into [the] Seaplane base in ZZZ on the VFR Arrival procedure at 1200 MSL.  After contacting the tower and being assigned the route arrival procedure the tower called out traffic for me 1 o'clock altitude unknown.  I told the tower I was searching for the traffic.  The tower told the conflict aircraft my position and they called me insight.  As I continued to search for the traffic an aircraft appeared at my 12 o'clock at extremely close range and my altitude head on.  I had little to no time to react but attempted to push forward and descend and avoid a collision.My aircraft and the conflict traffic collided head on approximately 5 nm north of ZZZ just South of the reporting point [landmark].  My aircraft continued to be controllable and I slowed the aircraft to reduce the risk of structural failure.  I could not see any obvious damage from the cockpit but had heard and felt the impact.  I told the tower I believed I have had a mid air collision and requested the tower to ask the other aircraft if they we OK.  I don't know if anyone responded to the tower.  I continued into ZZZ and landed in the water lane without further incident.  Upon parking the aircraft in the float slip I inspected the aircraft and found minor damage to the right hand fiberglass wingtip from the collision.  No other damage has been discovered at this point.I called the tower on my cell phone and told them I had made contact with the other aircraft.  I then called the FAA and reported the mid air collision.  My aircraft is ADS-B equipped but I believe the other aircraft was not.  I never received any warning on my traffic display and I know it was working from other aircraft warnings on the same flight earlier.  I still do not know the identity of the other aircraft.The area of the [landmark] north of ZZZ is a high traffic area and possible collision risk.  I have operated out of ZZZ for XX plus years without incident.  I believe if the other aircraft had ADS-B and or mode C we could have avoided the collision.  I don't know what could have been done better with the exception of ADS-B on the other aircraft and honestly feel lucky to be alive.




Synopsis: Seaplane pilot reported that during VFR arrival a collision occurred with another aircraft. The reporter stated that after landing they found minor wingtip damage.
