Positively, you get to see the hole in the ground where she lived with the stone basement frame and stone steps, and you can see a well. They have a few medium sized boards to read along the "path". The scenery is ok. They have a gift shop too with a good number of Anne and PEI items. If you are a devout worshipper of Lucy Maud Montgomery, then you should make the pilgrimage.
Negatively, it costs money to get very little. At the gift shop, the "tour girl" rambled off mechanically behind the gift shop counter a very short explanation of the grounds. They had no washrooms on site either! No people that were maintaining the grounds reached out to make the tiny area that you go to more interesting. Wow, ridiculous! We wouldn't have paid for that if we hadn't purchased it in a bundle with other activities.
If you wander in from the Anne of Green Gables' Haunted forest path, you will see no signs warning that you have entered a new site that you need to pay for. Most people that don't know the area assume that it is a extension of the main Anne of Green Gables site that they have already paid for. You do have to cross a road to get there though. If you walk 2 steps out of L. M. Montgomery's gift shop and swing your head to the right turning slightly, then you will see the only place that indicates that you need to pay to get in. Also, if you walk straight ahead out of the gift shop, then you might not see any indication of your need to pay, and be walking through a field that looks like nothing, but you may have to pay for (like one Google reviewer said). They don't say anything in the bookstore either that you need to pay to look around the grounds.
