Hit the trails today. First off, have $8 cash for the entrance fee. I recommend parking in the Black Bart day use near the bottom. It's a good/tough hike back to the top, but you'll thank me later. There is another day use parking just north of BB where the intermediate entrance to the trails are. That's a fun ride to a three way fork. The trail then split up towards the entrance or down into a steep drop followed by a quick wrap around trail with lots of climbs not for the weak legged. The Superior trail entrance is located near the restrooms by the main park entrance. This trail is a fast downhill single track filled with several switchbacks. Lots of fun! The trails are fast and you can get several runs in. Beware though, you will do some hiking on either trails or the main road. I'd rate my skills as intermediate and this was a challenge.
it's a decent trail, and it's fairly close by if you live in the Modesto area and if you're bored of the Dry Creek trail. It's a pretty short trail but you can take it numerous times and it's still fun. You can spend a couple hours there and take all of the trails but they are in pretty good condition. if you go during the week, there is almost nobody there. there's a few people on the weekends but it's never been too bad. the switchbacks are fun but watch out for the poison oak surrounding the trail in some areas. you should have some decent tread and your brakes should be n good working order before you head down the trail. I do suggest you park at the bottom parking lot so you don't have to pedal back up to your car after the fun downhill trail. also depending on when you go you have to pay to get in and I might be wrong but I think it's around $9. I suggest you go in the fall, winter, or spring because it can be nasty hot in the summer.
Rode this trail for the second time last weekend, 7/31/10. It is challanging for the first 1/4, the stairway switch backs are a BLAST, then a great ride for the rest of the trail. I suggest parking at the bottom and starting your ride going to the top, where the trail starts, on the road, as this is the HIGHEST demand on stamina. Grouling uphill is really difficult after your ride on the trail.
