West Mountain (6,904 ft) is the large summit right at the south end of Utah Lake. 

The Grotto Waterfall & trail is more of a stroll, rather than a hike. At only 0.25 miles one way, this trail is very kid friendly. 

The Spanish Fork Cross, as known by locals, is a very short yet rewarding hike that leads to a giant white cross on a hill that overlooks the town of Spanish Fork, Utah to the North, and has amazing views of the mountains and Spanish Fork Peak to the East and South. The Spanish Fork Cross trail is near the Spanish Fork Reservoir and Campground, and is perfect for kids and dogs.
