Went to look for these today. Could not find Hagrid or You Know Who. The terrain has many trees down in the past 6 years, and it's highly unlikely that the box at first tree on the path would not have been uncovered. We went for the hike with no expectation of finding them. Not sure when the planter will update status. Gave up trying to figure out which picnic grove might possibly be the starting point for Harry. None of the names really sounded like the patronus.

These were great!!! The last one was so fun!

Didn't have much time left as the kids were getting hungry. So we skipped straight to Harry. We are all big Harry Potter fans so I hope to get back there in the future. Box is in good shape. Beware though of some thorns in the area. They got my legs pretty good when I was putting the box back.

Still findable, but area is overgrown so you might want to wear long pants. Since right beside path, it is not hard to find once you see through the weeds to the log described.

box 2 was out in the open on the trail near the hiding place. We stamped it and hid it.
My kids loved the Harry Potter series. We found all 4 of your letterboxes on 5-25
