Makamah Preserve is a small but pleasant nature preserve off 25A in Northport, just south of Crab Meadow.
It's great for a short walk with the family. My favorite part is a small, swampy lake near the entrance on Makamah Road.
There's a trailhead on 25A, but in my experience the path from there is usually overgrown. A better way to enter is to drive left on Makamah Road (off 25A). After a few minutes, you'll come to a small entrance on the left. You can park on the road.
There are several paths in the preserve, none of them too long.
A Short Trail in Makamah Preserve
Here's a pleasant, 2 mile loop that should take no more than an hour or so. It starts at the entrance on Makamah Road. (This was recorded with Motion X on my iPhone.)
