Jakes Branch seems like relatively new park, with a 4 mile trail in addition to the usual ball fields, tennis courts, and picnic areas that county parks usually have. Be sure to head up the center's observation deck for a view of the park from 5 stories up.
Trails are typical easy and flat pine barrens, with no real viewpoints. There is traffic noise due to being right off the Parkway.
Double Trouble's trails are actually sand roads to service the cranberry bogs. It's interesting walking around and between the bogs... but it's not really what we consider hiking. It's better for a little stroll or taking the dog for a walk, but fine for a cold weather hike too.
We did the 2.25 mile Perimeter trail and the 1.25 mile Reservoir Sawmill Loop. There is also a 1.5 nature trail.
