One way per person from Katahdin Air
This is a short flight chuck full of benefits. If you would like to bring a few extra items that you might not hike in with a fly-in trip works well. It saves time. You cannot see Katahdin and its fascenating neighborhood from a more unique perspective. If you are interrested, "only a seaplane can visit an area and leave without a trace." Yes, you will probably see a moose or two on your flight in.
