On our trip to Door County we hit up many of the more accessible lighthouses. If you're looking for some great pictures from your trip to DC, be sure to check these out. The last one, which was actually our first stop, is my absolute favorite.
1. Cana Island Lighthouse - This one is located on an island within a park. There's a $7 fee to go into a park, and then an additional $5 if you want to climb up into the lighthouse. I probably wouldn't take my family here in terms of bang for my buck with small children, but if you're into maritime history, they have a lot of really cool info on site. One last note - there is no running water on the island, so plan accordingly.
2. Range Lighthouses - These took us forever to find, but once we did, we were able to walk right up. The lower and upper range lights are not technically lighthouses as I would define them, but are included on the tour, and still create very cool photos. Especially if you need your traditional gym mom handstand pose.
3. Eagle Bluff Lighthouse - Probably my second favorite lighthouse that we visited. This one is also inside a park, and there is a $5 day pass that you need to buy, but the view, the flowers, and the experience make it worth the pass, for sure. We stopped all along the way to take pictures before we even got to the lighthouse.
4. Sturgeon Bay Canal Pierhead Light (and Sturgeon Bay Ship Canal Light) - So this one was my absolute favorite in terms of view and the actual lighthouse itself. It's a little awkward to get to, because most of the property is run by the Coast Guard, and there are all kinds of fun signs about trespassing and Homeland Security. However, don't be driven away, you ARE allowed to go see this lighthouse, and it is beautiful.
