My husband had a lot of great ideas for what we could do in Utah when I came to visit during our courtship months. We were a long distance relationship, so whenever we did get together in Utah he would usually have a lot of things planned. Here are a few things we did:
1) Hike to the Mount Timpanogous Cave. It's not a very long or difficult hike. I loved the view of the valley. Here's a link for more info: http://www.nps.gov/tica/
2) Wheeler Farm. It's a beautiful historic site located in Murray which you can visit free of charge. There are great spots for picnics, a historic farmhouse you can tour, and lots of farm animals. Here's a link for more info: http://www.wheelerfarm.com/
3) Desert Star Playhouse. Located in Murray, this is a great theater to go to if you want a few laughs. Their shows are always entertaining and fun, and very unique. http://www.desertstarplayhouse.com/
4) Hike to Ensign Peak. This historic Mormon site offers a great view of Salt Lake City and the entire valley. The hike itself is short and not very difficult. It's a very popular date idea in the Salt Lake area. I love hiking up and taking photographs of the valley. Beautiful! For more info: http://www.utah.com/mormon/ensign_peak.htm.

5) This is the Place Heritage Park. A pioneer village full of replicas and original pioneer homes and buildings. They always have fun and exciting things going on in the summer. It's definitely a must see! http://www.thisistheplace.org/
