What a kick.The boulder field is a short walk, like a block away from the parking lot, close enough that someone with walking difficulties could get there, even in a wheelchair. It is not paved but firm ground with a few obstacles. One does not have to climb about the boulders to test out the sounds of the rocks, but it is more fun if you do. About 15 other people were scattered around the day we were there, many of them children having a great time hitting rocks. Some rocks go THUD, others RING and one gets pleasure from hitting them yourselves or listening to the children's gleeful response when they find a great sound. If one keeps going on the trail it leads to a sweet waterfall. Where we observed children getting way to close to the edge where a fall could of been disaster but that was a parenting issue, easily avoided by parents who want to take kids to see it. Getting to the waterfall is probably less than half a mile. We went not knowing how much walking would be necessary. Outhouse only I believe.
