wide enough for 2-way traffic; some blind spots, so be careful. Trail is smooth, so downhill bikers are often riding pretty fast.

This intersection marks the terminus of the bikeable Lower Hull's Gulch trail. Beyond this point is pedestrian only but Lower Hull's Gulch is a great little ride that riders need to take care on due to its popularity with hikes, runners, etc.

No matter what time of year, whether you are a hiker or a cyclist, it is a beautiful area to unwind and take your mind off things! In my opinion, there are no places to rest here apart from nature itself, that should be taken into account.
