Get a good hike in on the Mirror Lake Trail with your furry pal. The 5-mile trail has a 265-foot elevation gain, perfect for first time hikers. The route style is a loop, and the entire trail is paved, making it an easier hike for you and your dog. The trail will take you around a lake and gives you an amazing view of Half Dome, plus you will go across a few bridges and climb over a river. Your dog needs to remain on leash while you hike this trail, but won't mind since he will be too excited for the hike.
