My current petsit is in Thunderbird Heights, which means I have Thunderbird Falls literally in my backyard. I've hiked there in the winter, which was spectacular, but I've never had the chance to hike it in the fall. The trail to the lookout point is only a mile, and it's a beautiful hike through the forest with a steep cliff on one side. Then it's a muddy short hike down to the falls. Unfortunately, the trail directly next to the falls is pretty eroded and there's a barricade up, so I couldn't get too close, but it is a great scenic stroll nonetheless.
