Stock Jeep can make it. Some of the mudpits can be be unknown depending on how much rain we've had. You can always go around. Plenty of room on most of the trails out there. I wouldn't go alone though, unless you've got the right recovery stuff. I forget which one is which, so I can't say which is more difficult. I recall the lower trail having more mud than the upper. Once you hit the end of the trails, you'll get to the lake. Good place for lunch/picnic.
