Cloudy, cool day. We had done Mt Lake loop several times before so wanted something new and added the Twin Lakes extension including the loops around both. Parked at the second small lot closer to the Twin Lakes end of Mt Lake. So many great views of each of the three lakes. Just above the larger Twin Lake encountered the private property of the YMCA which also should be accessible via Raccoon Point road and it's connecting roads. We respected the private property and turned back. Overall the trails were very well maintained with excellent signage. Encountered a number of other hikers around Mt Lake but only few on the trail to and around Twin Lakes. Although rated moderate difficulty, I would rate it easy and recommend for anyone preferring a beautiful hike away from crowds.
We combined this hike with the add on loop to cascade falls. Very nice views and changing terrain. Steep in sections and the stated elevation gain is misleading as the ups and downs are near constant. We started and ended at day use beach, great views of lake all around the loop.
