Happy Isles is located just below the confluence of the Merced River and Illilouette Creek. An island with some footbridges connects to the "mainland." The area has dense forest, flowing water, and abundant birdlife. This area takes on different personalities during the different seasons. In winter, Happy Isles is a quiet place to view the rivers flowing with snow-covered boulders and rocks and ice forming in the slower pools. In springtime, it is awash with blooming dogwood and raging water. In summer, the area is intensely green, and the water flows at a gentle pace. In fall, Happy Isles is one of the most colorful areas in the valley with oak, dogwood, and broad-leaved maple trees all a splendor in autumn's glory.
