The circular trail is really great, especially with children. Good footwear is recommended in wet weather, as it can get quite muddy in some places. Please note, it is not suitable for strollers. The paths are very narrow, and you can only walk single file. Alternatively, you can just hike the valley trail there and back, which is accessible with strollers and other vehicles.
