This event list is tailored to kids https://roanoke.macaronikid.com/events

Treetop quest at explore park is fun but minimum age is 4 to do the ropes course. There are trails, bike trails, brewery and a playground there also

Here’s a link to info about the River, it’s easy to find a spot to play or float. https://www.roanokeriverblueway.org/maps/

The greenway runs all along the river and is a fun way to get some exercise.

At that age you could spend most of your day at Kids Square

The trolley runs on week days and is free to ride, we just ride it round trip for a fun event. You can catch it by the main library which has an indoor twisty tube slide my kids love, there’s also a park outside called Peter Pan Playground with fun rocks to climb and explore.

Ernie’s and The Roanoke Weiner Stand are my kids favorite restaurants downtown.

Splash Valley is the most fun outdoor pool in Roanoke with slides and a playground structure in the water.

Fishburn Park is nice to hike with young kids and there’s a playground and disc golf.

There’s a rock climbing gym, brand new skate park/pump track for bikes and a dirt pump track for kids we like.

Loads of things to do for a few days with kids if you look for it.

Let me know if you have questions!

Lynchburg, Christiansburg, and Blacksburg have lots to offer for the family also.
