One of my favorite parts about Utah is the landscape diversity. We love the mountains around us, and those mountains bring lots of lakes, rivers, and streams. Sundays are often slower days (but not always, and not recently), and we love to get out as a family then. This last weekend we headed up to Tibble Fork Reservoir in American Fork Canyon.
Within the last couple of years, a new dock and a decent sized sandy beach were added to the dam. The water is always cold due to snow run off, but it’s a beautiful destination. Bring wind breakers and sunscreen!
We also checked out the Tibble Fork Loop trail, but turned back probably a mile into the hike. The trail was extremely narrow and tilted toward the water, and my kids don’t know how to swim yet. It was still a lovely jaunt through the forest. 
Special note-you do need a National Parks Pass or to pay for a 3 or 7 day pass to get in. Bring sand toys and check it out!
