Hiked this with my wife and our sons who are 7 and 9. The hike itself wasn't terribly difficult or unusual in any way. Our final impression was that the length of the trail was the biggest concern for our family, yet both of our kids managed very well. The views from Avalon were wonderful while the views from Field were somewhat disappointing in that there were only two partial lookouts. We attempted to find geocaches on both peaks during our visit but only found the geocache on Field. Due to the extra distance we decided not to hike Mt. Tom. Therefore we hiked Backed down the Avalon trail to Mt. Avalon where we enjoyed the views a second time.
