Yes you can! Whether you participated in Fern’s Expedition or not, you’ll have access to the Woodlands map and Fern’s tent.

And even though the Event is now over, you are still able to redeem Pathwords in game and experience Moments. To redeem a Pathword, press on the Woodlands map and then press the map and compass icon. You can then input the Pathword and press submit and you will still be able to experience the Moment, and if the Pathword is a Special Guest Pathword, you will also receive an in-game item.
