You have to pay $5 to park at the trail head. If I remember correctly, you only have to pay before 6pm.
$5 to park art the trail head. You fill out an envelope and put the receipt in your window. Put the money in a drop box.
Recreational parking pass is for access to most NH state parks - a fee you pay one time for the season, year, etc.
It's a pass to pick up right at the entrance of the trail to get to Diana's bath you pretty much grab an envelope put the $5 in and drop it in the box and the ticket or parking pass I should say you rip off of the envelope
It's also not enforced as it is an un-manned pay station.
It is a fee to park and access the site you are visiting. Usually the money is used to the upkeep of the place you are visiting and allowing public access
