“Enchanting” is the description frequently applied to this park in the Berkeley Hills. At the sight (and sound of the “toot, toot”) of a 15-gauge miniature steam engine trundling through, children heartily agree. There’s an antique carousel, an Environmental Education Center and Little Farm, too. Bring a kid and some lettuce to feed the animals. Take a train ride and a spin on the merry-go-round. Enjoy the views. Containing a botanical garden sanctuary for many of California’s rare plants, this is also a place for visitors to hike and wander, connecting to the much larger, 2,000-acre regional park system. Plus, admission is free! ebparks.org/parks/tilden<
