Do I need a parking pass to park here, because of social distancing? I know in the past it was always first come, first serve format?

It is still very crowded, social distancing is really up to you as the previous writer stated.

You need to pay $5 to park but that can be used all day at different spots along the Kancamagus. Still first come first serve, unforently if theres no parking then you're not getting in. Nothing has changed for social distancing, it's up to you to distance yourself from others. I was just there about a week ago
