South Waldo Lake trail climbs steeply from the intersection of Mt Ray trail if headed South. There are a couple rocky drainage crossings to navigate to keep you on your toes and some of the pitches will test your endurance and leg strength. From here the trail is more rolling the terrain opens up quite a bit to old growth hemlock and rock outcroppings. Near the intersection with Fuji Mountain Trail # 3674 the trail passes between the Island Lakes and continues on to Mt. Ray trail. The Island lakes are a sight to see. Small, pristine and enchanting.
North of the Mt Ray Trail intersection the South Waldo Lake trail enters the Waldo Lake Wilderness which is Closed to Bikes. South of Fuji Mountain trail the trail becomes a little more remote and can be overgrown to the point of being almost invisible the farther south you travel.
