We visited Gordon's Park for the first time during the Perseid Event in August and to try out astrophotography for the first time. I had booked the overnight stay via email and had requested a spot with more privacy as we planned to get up in the middle of the night for photos and didn't want to disrupt others. Site 40, although smaller than some of the other sites (especially with a large vehicle like ours), proved to be a great, more private spot and grew on us over our 2 night stay.
Although we didn't stay for the entire evening talk, we enjoyed the telescope experience led by staff and enjoyed the educational components too.
The main office/campground and the dark sky preserve campground are not one and the same. The dark park entrance is a just up the road off of Star Lane (which could be better signed from the road). The park is fairly open with few trees/shrubbery, but the sites are farther apart, which provides some privacy. The entire campsite has very little shade during the day, so come prepared with a large umbrella or other options for shade. There is a bbq and tools for guest use, which we used for our dinner rather than bringing our campsite bbq along - very convenient! The privys were always clean and well stocked with tp and sanitzer.We didn't take showers and swam instead, though I did inspect the shower area at the main office on our way out and they seemed clean and well-maintained.
After the moon sets, the sky is so clear and well worth the wait. We really enjoyed the experience overall and will definitely be visiting dark parks in the future!
P.S. If taking the Chi-Cheemaun ferry, make sure you book early and arrive early for boarding (1.5-2hrs prior). Just because you have a reservation doesn't mean you get a spot!
