Madison, Wisconsin is one of the friendliest and liveliest state capitals in the United States. The city is home to the University of Wisconsin-Madison and has a reputation as an active, innovative and cultural hotspot in the Midwest. If you are looking to plan a memorable outing with your sweetheart, here are some of the best places to propose in Madison.

Madison has a fantastic bike trail system - one of the best in the US - and when the weather is nice, there's no better way to spend the day than exploring on two wheels. Pack a picnic lunch, and hit the Capital City Trail or the Wisconsin Road Cycling Course. Time your romantic proposal for your lunch break; find a quiet spot where you two can be alone, then ask her to marry you with a diamond engagement ring.

Explore the gorgeous Olbrich Botanical Gardens - 16 acres of outdoor gardens (free admission) and a tropical indoor conservatory ($2 admission). Scope out the gardens in advance to narrow down your list of the best places to propose. The Rose Garden, the Perennial Garden and the Sunken Garden are excellent places to start. You could also plan your romantic proposal during one of the gardens' outdoor concerts or during Olbrich's Blooming Butterflies festival in the summer - when butterflies emerge from their chrysalises and fly around the conservatory.

Sign up for a couple's treatment at Madison's Indulge Spa for a day of pampering and relaxation. Share a unique experience with the specialty rendezvous massage, where two therapists provide simultaneous massage or body treatments for you in your own private suite. Ask them to leave you with a few minutes of quiet time after the massage, and take that opportunity for your romantic proposal.
