Took the kids here for an "adventure" and everyone had a great time. I was paranoid about glass the entire time (kids were pre-schoolers) and that's the only reason it didn't get a 5. The 4 isn't a judgement against the trails (I plan on going back even with the still-young kids) it's just a word of caution.
EDIT: came back with kids. Not nearly as much glass this time and they really enjoy this place (so do I) so I have to change to a 5. This place makes me want to get a mountain bike.
It's a nice trail for a walk definitely walk opposite direction of the bikers. I took my husky and he enjoyed the little drops where he could jump of the rocks. It is kinda dirty though. I went around one and it wasn't busy it started getting busy as I was leaving around 4 on a Thursday.
Tara H. on Sansom Blue Trail
Great location. Some very beautiful scenery. Mostly very friendly people. I'm giving it three stars for the following.
1) Poorly marked trails.
2) There are non-hikers/m.bikers on the trail late in the afternoon that are sketchy. Don't go by yourself in the afternoon. Another hiker told me not to be out there late evening on the weekend because people are out on the trails or by the falls getting drunk.
3) Not very clean. There are bottles, glass and plastic, littering some of the trails. If you have a bike, or a dog, watch out for broken glass and shredded cans.
4) People are supposed to have their dogs on leashes, the two days we went there were people walking their dogs off leash.
Otherwise, during the day, it's pretty great, and my family will continue to hike this area.
