One of my favrite front range hikes near Denver CO: South Table Mountain. If you are in the area, Golden is a great town to visit. Great little downtown and lots of trails.

Hit me up if you are in the area and looking for a hiking buddy! I am always looking for a chance to meet new people to experience the outdoors with. :)
