g-t-, So.Mo. has some easier rides and it has some very advanced rides. The best ride for you will depend on your skills and what you want to do. So, it is hard to say what you sould do. Because So.Mo. has it all, you should definately stick around. If going the easier route, I suggest Desert Classic. Its an out and back of about 20 miles total and you can do as much of that as you like. Once you get to the trailhead, it will be difficult to get lost.
If you want to try one of Bike Magazine's top 10 trails in the country, you can do National. It is an advanced ride with many technical sections and lots of steps/drops. There are some variations of National that will give you a taste of what it has to offer that incorporate some more itermediate trails that allow you to pull out and return if needed relatively quick and easy. Most intermediate riders will enjoy National as it is always possible to walk the easier sections. A very common route for National is to take Morman Loop up, which connects to National. You can then continue up National to the infamous "Waterfall" and beyond. Continuing will take you to the Buena Vista parking lot. I do not suggest you continue on Nation after that without a guide. At whatever point you turnaround (the Waterfall, the National/Morman Loop connecting point, Buena Vista) you simply go back down National to your starting point. National and Morman loop both start at the same point at the trail head. Please please read this thread,
the whole thing, before you go.
