What to pack

What May feels like

Late May is blackfly season in the Maine woods, and nothing about the scenery will distract you from them at dusk. The Park Loop Road is open again by now and the crowds haven't arrived, so bring a head net and take the win.

Rain arrives about 8 days of the month, so keep one flexible day in your plans.

Can you swim?

The ocean runs about 48° — frigid — locals in wetsuits only.
