What Travellers Say
Reviews Summary
Happy Isles is praised as a beautiful and peaceful spot, ideal for enjoying nature and accessing major Yosemite hikes. Visitors appreciate the Nature Center and the scenic Merced River islands. Some note that the river's flow is best in spring/early summer, with late summer being less impressive.
"Happy Isles is a nice easy walk if you’re looking for something that isn’t strenuous. We went in late summer and the river wasn’t flowing much so there wasn’t too much to see there. If you’re going here, I’d recommend going slightly earlier in the summer, or even the spring."

"Happy Isles is a beautiful spot in Yosemite National Park, perfect for enjoying the natural scenery and starting various hikes. The small islands in the Merced River are picturesque, and the lush forest surroundings make it a peaceful retreat. It’s also a great place to learn about the park’s natural history at the Happy Isles Nature Center. A must-visit for anyone exploring Yosemite!"

"The best time to visit Happy Isles in Yosemite is Spring and early Summer time when the Merced river is roaring, and flowers are blooming. But Autumn is also a good time, there is no crowd around you, and the whole island is super quiet.
The trail is short and easy. It is about one mile without any elevation. There is a shuttle stop (called Happy Isles Shuttle stop, of course) right at the trailhead. It means you can park your car anywhere in the valley, then take the shuttle to the trailhead. A kiosk by the stop provides a map of Happy Isles. You will meet the Happy Isles Nature Center within 0.2 mile. Then cross a brdige over merced river and reach the two tiny islands in the middle of the river.
The first island is surrounded by Boulders and Trees, only a small trail cross the heart of it. You will meet another bridge at 0.4 mile, which leads you to the second island. In the middle of the bridge, there is a copper plaque honoring Steven Mather, the fournd of the National Park Sevice.
Happy Isles is also the start point of John Muir Trail. You can hike to Vernal Fall, Nevada Fall, and Half Dome by crossing a stone bridge over Merced River and follow the sign."
