If you both enjoy horseback riding, a romantic horseback ride in the Santa Monica Mountains or on the beach can be a great way to spend time together. Los Angeles Horseback Riding has rides at sunset, sunrise or under the moonlight, with or without food. All rides are guided, so coordinate with your guide for the setting and space you need.
