The Stanfield Marsh Boardwalk is a lovely 1.6-mile path along Baker's Pond, located at Stanfield Marsh and Wildlife Preserve. This peaceful boardwalk offers fantastic wildlife-watching opportunities, with views of birds such as ducks, geese, herons, and even Bald Eagles. The preserve, situated at the intersection of Stanfield Cutoff and Big Bear Boulevard, features easy access with parking available at the corner or along the bridge. The boardwalk is also dog-friendly, but biking is not allowed. You can lock your bikes at the parking area, take a break from the saddle, and stroll down the boardwalk.

This windy but picturesque stretch is just a small part of the 110-mile-long Rim of the World Scenic Byway. Here, you'll enjoy great views of the San Bernardino Mountains as you navigate the curves, but please proceed with caution. As you ascend from San Bernardino, the climate shifts dramatically from desert to mountainous oasis.

This lightly trafficked, stunning road lined with alpine trees leads from Highway CA 18 up to the small town of Green Valley, where there's a beautiful lake. If you're heading up to the lake, be prepared for a climb of over 1,000 feet. It's fairly steep, but the views make it well worth the effort. Alternatively, the ascent offers an enjoyable experience as well.

Green Valley Lake sits at 7,000 feet, higher than both Lake Arrowhead and Big Bear. It's secluded, about four miles from State Highway 18, surrounded by National Forest. This small, scenic lake is uncrowded and ideal for a peaceful retreat.
