A decent spot for paddlers
It was a good time, camping at Peconic. The convenient location next to a lake is ideal for anyone who wants to paddle. The site's got an outdoor shower, though there's no hot water. And the host sells firewood too, which is quite convenient.
There are quite a few things to note that might make this campground not for everybody:
Long Island's woods have an overarching tick problem, and unfortunately Peconic Campground is no exception.
The site has an outdoor shower, but no hot water. There are also portta potties that are in surprisingly no-so-bad condition.
The path to the lake is a little unfavorable; it's a row of long wooden boards thrown in a line over ponds. It gets the job done, but it's not convenient for everyone, especially for anyone hard at walking or carrying a heavy boat.
The lake is nice and sizable for boating and fishing, and it turns to river both to the East and West. Both directions have a few dams that require getting out and carrying your vessel(s) to continue exploring. This might sound like a bad thing (and it probably is for some), but I'm strong enough to be able to tolerate it. Plus, it adds character and aesthetic. To the East, after 3 land stops, Roadhouse Pizza is along the river. We like to stop there for a slice! There's a ice cream shop near there too, though I haven't stopped there yet.
Overall, it's a good time at Peconic, despite the flaws. Just be sure to check for ticks throughout and after your trip!
