My friend Ali and I did this entire loop today. First, for any more people looking for this trail, it is NOT Silver Lake Road off of the 50, it is Silver Fork Road and it is 8.7 miles to the turn off. We did the 8.6 mile loop and i would definitely say this does not fall under the difficult catergory. Moderate would be about right. You climb the first two miles about 800 feet, after that it is very gradual the rest of the trip. The creek was very high so to complete the loop we crossed downed trees, one at around the 4.5 mile spot where there is a campsite and fire ring, and then crossed back over about 6.5 miles and then rejoined our original trail. The trail on the far side after crossing the first time is much rougher, many downed trees, snakes (saw 2), bear feces, etc. You can tell many people do this trail as an out and back and the first section through the meadows is very pretty. In fact if i were to do it again, i would do this as an out and back, forget about crossing the river (not a creek) and enjoy the beautiful meadows. But for a trail close to the 50, and a good steady climb, this fit the bill. Bring your bug spray! Yozers!
