You can go any day anytime but the observatory opens only 8-10m Sat night. Other time u have to park yr car out of the gate and walk a little bit to get there. Very nice n high point. Good for star gazing.
As we are on Jenny Jump State Park land, the property is open to the public until dusk. After dusk we are only open to the public Saturday 8-10:30pm, from April until the end of October.
Check their website: www.UACNJ.org. in addition to public nights every Sat April thru Oct, there are a few special events, as well
Saturday nights til October .
