Irvine Regional Park

Nearly everything a small kid dreams about, the train, the ponies, the petting zoo, packed into one shady oak grove in Orange, all doable at a toddler's pace.

At most parks you pick one thing and drive home before the meltdown: a zoo day or a train day, a playground or a picnic. Irvine Regional Park lets you skip that choice. James Irvine Jr. deeded this 160-acre oak grove to Orange County for a single dollar back in October 1897, which makes it widely regarded as California's first regional park, and it still shelters some of the oldest coast live oaks in the county. That means shade, and a lot of it.

The kids will make a beeline for the rides. A ten-minute miniature-train ride that loops past the lakes for about seven dollars a head. Pony rides for around eight, cash only, every day but Monday. The eight-acre OC Zoo, which costs two dollars and is full of rescued locals like black bears, a pair of mountain-lion siblings, and a bald eagle, plus a barnyard where goats and pigs will happily investigate your toddler's snack. Six playgrounds are scattered around, so there is almost always one within eyeshot of your picnic blanket.

Two dollars to stand in front of a black bear beats most things two dollars can buy.

When the little ones start to fade, there is the lake, with paddle boats and aqua-cycles (about twenty-two dollars a half hour) and a photogenic old waterwheel nobody walks past without stopping. Rent a surrey or a bike, or just push the stroller down the flat, paved trails under those hundred-year-old oaks. If you want to line up ride prices and hours before you load the car, the Irvine Park Railroad plan-your-visit page spells it all out.

Now the fine print. Entry is free, but parking runs three dollars on weekdays and five on weekends, and it climbs on some holidays, so bring small bills and a little patience (the OC Parks page has the current details). Every attraction is pay-per-ride, which adds up quickly, so the smart play is to pick two hero activities and let the free playgrounds and trails carry the rest of the day. There is a Lakeside Snack Bar, but it is snack-bar food, so pack the real lunch. The sweet spot here is roughly ages two to ten, and the train, ponies, and petting zoo are toddler gold.

Come early, before the reservable shelters fill with birthday parties and the good parking near the zoo vanishes. Time the visit around the nap, not against it, because there is enough here to strand you well past a cranky preschooler's limit. In the warm months the park opens at six in the morning and runs to nine at night, so a slow, oak-shaded morning is very doable. Verdict: the rare all-in-one where two dollars, a train ticket, and a picnic blanket buy you a whole day.
