Start at the trailhead across from the cemetery and follow the yellow trees! I would definitely recommend this one. Trails are nice, nothing too crazy steep. Nicely shaded. If you follow the loop and come out to break at the lodge lot, go down the stairs and you'll find the most beautiful view that leads right back to the trail loop. (Right along the water) We did about 4 miles in 2 hours. Watch for spiderwebs!
Did this a couple months back and I must say this trail isn't one that I'll return to, it had little to see and a large portion is bridal trail for someone who likes an "exercise" trail this is great for wearing you out but there isn't much payoff for sightseeing, not really anything but trees unfortunately.
My husband and I camped out here the past 3 weekends. The lake and camp ground are wonderfull. Its small and not super busy, we always camp in the primitive section. Access to the trails are very easy to get to. There are several different points you can start depending on how far you want to go. We did the shortest section the first weekend, the longer of the two on the second weekend, and the entire loop last weekend. We both agree we aren't in the best of shape, but the roots and hills on this trail (Michael Tygart Loop) are pretty rough for mountain biking. We had to walk our bikes a good part of the way. There are some interesting things around mile 2 thru 3 (begining at the maraina), where you can walk a short distance off the trail and see some abandoned homes built in the late 1800's. We got to go inside one and look around. There are horse trails, a boyscout tropp camp, and really nice views.
This trail is actually goes by the name of Michael Tygart on the state park map. It's closer to 8 miles, and it's misleadingly referred to as a loop, even though it starts at the lodge and ends at marina (which are about a mile apart, making it almost 9 miles that way). This trail makes for a great run, however, be prepared for a tough uphill around the cemetery after you cross the road about 1.25 miles into the hike. When you reach the next road about 3 miles later, you will go up the road about .25 miles until the trail reappears around the Claylick Loop trailhead. I didn't know about this the first time on the trail, and I became fed up searching for the other half of the trail, so me and my friend just turned around and ran back the way we came. But the next time we returned, we found where the trail restarted, and the last half was well worth the trouble of searching for it. After you descend downhill, the next two miles are nearly flat. Around the time you get back to the lake, you have about 1.5 miles left of rolling hills and spectacular views of the lake. Unfortunately, when the trail ends, you are still a mile or so away from where you began, so if you don't have anyone to pick you up from the marina, you will have to walk the road back to the lodge. (Bummer.)
Bernie C. on Greenbo Lake Trail
Nice trail clearly marked and seems that most could walk this trail with little problems. The views are good and trail is well maintained.
