The museum does free tours, but donations are appreciated. It is a great place to learn more about the MKT railroad's history. The museum has a caboose that you can enter and is located along a railroad. It also provides information about tourism in Katy.

The park has many restored historical buildings. There is also great landscaping, as well as a brick plaza. It is a great place to walk around. You can rent the buildings by calling the Katy Heritage Society at +1 281-391-2550.
Typhoon Texas is a large waterpark with slides, a lazy river, a wave pool, and more. Great to go on hot summer days to cool down or just to have fun.
Barker Reservoir
A large park that covers 7,800 acres, with over 11 miles of hiking/biking trails with wooded paths along Buffalo Bayou and a long loop trail along the top of the Barker Dam that also connects to the Terry Hershey Park providing bike paths all the way east to the Sam Houston Tollway. The extensive recreation facilities in the park include soccer and baseball fields, picnic areas with tables and grills, a dog park (with ponds), a shooting center with trap, skeet, and rifle target ranges, and equestrian trails (but no stable, so bring your own horse). Runway for radio-controlled airplanes. Be aware that the park is closed due to flooding whenever there's been recent thunderstorms or hurricanes (the land is actually owned by the U.S. Army Corps of Engineers who built the dam and manage the land as a flood control project for the Greater Houston area).
