Lamoine State Park represents the way most Maine state parks should operate. Way ahead of both Camden Hills and Cobscook with regard to cleanliness and upkeep. Showers were surprisingly good and often cleaned.
There are two non-reservable sites right on the Bay--- do try for one of those when you check in…just in case.
The public dock is an interesting spot to watch in the evening as boats are unloaded.
One more thing-- bring your charcoal for the grills along the Bayfront.
RV's seem to be up higher on the hill while tents prevail lower down.
46 & 48 seem like good sites. Many sites are not level. Some also are grass covered rather than gravel so you might inquire if it is important to avoid a grassy site.
