Allerton Garden (National Tropical Botanical Garden)

A spectacular botanical garden in a lush valley on Kauai south shore that was used as a filming location for Jurassic Park. The guided tour takes you through themed garden rooms with massive Moreton Bay fig trees, exotic tropical plants, and water features. Kids recognize the Jurassic Park trees immediately and the scale of the ancient trees is genuinely impressive. The valley setting with the stream running through it is beautiful. The McBryde Garden next door offers self-guided tours through a larger area. Reservations are required for both.

Halawa Valley Cultural Hike

A guided cultural hike through the ancient Halawa Valley to a beautiful 250-foot double waterfall (Moa ula Falls). Access to the valley trail is only through a guided tour with a local Hawaiian family who shares the valley history, culture, and legends along the way. Kids learn about taro farming, Hawaiian plant uses, and valley life. The waterfall pool at the end is deep enough for swimming. The valley itself is stunningly beautiful with the green walls rising on both sides. This is an authentic Hawaiian cultural experience, not a tourist operation.

Inner Space Cavern

One of the best-preserved caves in Texas staying a constant 72 degrees year round which makes it a brilliant beat-the-heat option on a blazing Austin summer day. Kids are wowed by the massive stalactites and stalagmites on the one-mile paved Adventure Tour and the guides pace the experience well for families with younger children. The cavern was discovered in 1963 during highway construction and still contains Ice Age fossils of mammoths and giant sloths which gives kids something genuinely cool to talk about afterward. Tours depart every 20 to 30 minutes so you rarely wait long.

Longhorn Cavern State Park

Longhorn Cavern State Park is one of the most unique underground experiences you can share with kids in Texas. The guided walking tour covers about a mile through a massive cave system carved by an ancient underground river, and unlike most cave tours, the path is mostly flat, dry, and well-lit - making it manageable for kids as young as 4. The cave stays a constant 68 degrees year-round, which makes it a perfect escape from Texas summer heat or a cozy winter outing. Cathedral-sized rooms open up along the route, and your guide will point out fascinating geological formations along with stories about the cave’s wild history - it served as a Confederate gunpowder factory, a Prohibition-era speakeasy, and a hideout for Sam Bass’s gang. ...

The largest commercial cavern in Texas with massive formations illuminated by dramatic lighting on guided tours that descend 180 feet underground.

The gem mining and panning activity keeps kids busy for a surprisingly long time.
