Brookvale is a 4 mile loop trail located near Queens, PE and is rated as moderate. The trail is primarily used for mountain biking and is accessible from June until September.
One of my favorites on PEI. Fairly rooty with moderate flow. There are more trails than shown on the map. Good for 1-2 hours. Not sure the total mileage but it's much more than listed above. My last ride was 5 1/2 and there is a lot more there.
