Old Settlers Park is at 3300 East Palm Valley Boulevard, Round Rock, Texas. Published acreage varies by source — you will see 645, 658 and 670 acres quoted — but the point stands either way: this is one of the largest municipal parks in Central Texas, and it is the reason Round Rock can call itself a sports city without embarrassment.

What is actually in it

The inventory is the story here, because the scale is genuinely hard to convey otherwise.

Baseball and softball: a 20-field baseball complex and a 5-field softball complex. Twenty-five diamonds in one park.

Soccer: a full soccer facility large enough to host tournament play.

Tennis and basketball courts, and sand volleyball courts.

Disc golf, with its own parking area across the lake.

Cricket — which is not a facility most American municipal parks provide, and reflects who actually lives in Williamson County now.

A lake, trails connecting the whole site, playgrounds, and the Rabb Pavilion and Lakeview Pavilion for events.

Rock’N River water park, inside the park.

And Dell Diamond, the 11,631-capacity ballpark, sits at the eastern end of the same corridor at 3400 East Palm Valley Boulevard — the trail system connects directly to it.

Rock’N River water park

The part families come for. Rock’N River Water Park sits within Old Settlers Park and runs a lazy river, water slides and a water playground for younger children.

It is being expanded. A two-story pavilion and an enlarged river featuring two manmade waves have been under construction, which will change the offer meaningfully when complete.

Being an outdoor water park in Central Texas, it is strictly seasonal and strictly weather-dependent. Check current opening dates and hours directly before planning around it — and note that Round Rock also has the enormous indoor alternative at Kalahari, which runs year-round.

The $230 million bond — why this park is a building site

Worth knowing before you visit, because you will see construction.

Round Rock voters approved a $230 million park bond in 2023, and $151 million of it is going into Old Settlers Park. That is an extraordinary sum for a single municipal park and it is transforming the site over several years.

The practical effect for a visitor is mixed. Facilities are being upgraded and added, which is good. Sections are closed or altered at various times, which is not. Check what is open before you go rather than assuming a map you found online is current — during a multi-year rebuild, it very likely is not.

The sports-tourism engine

Round Rock markets itself hard as a sports destination, and Old Settlers Park is the machinery behind that.

The park contains a 60-acre multipurpose complex that hosts national tournaments in soccer, football and other field sports. The indoor Round Rock Sports Center on Chisholm Trail Road complements it, and since opening in 2014 sports tourism in Round Rock has generated over $148 million in economic activity.

What that means on the ground: on a tournament weekend, this park is extremely busy, the car parks fill, and the surrounding hotels sell out. On an ordinary Tuesday it is a very large, very quiet park. Those are two completely different experiences of the same place, and knowing which one you are walking into is the single most useful piece of planning advice on this page.

How to use the park if you are not here for a tournament

Most visitors are not, and the park is excellent for ordinary use.

The trail system is the best way in. It links Dell Diamond through the soccer complex, past the Rabb and Lakeview pavilions and the playground, across the lake to the disc golf area. That is a genuine walk rather than a loop round a field.

The lake and the pavilions are the calm end of the park and the right target for a picnic.

Disc golf is free, uncrowded on weekdays, and has its own parking so you can skip the busiest lots entirely.

The playgrounds are the answer with small children, and they are away from the tournament fields.

Weekday mornings are the sweet spot. Weekend tournament days are the opposite.

Getting there and parking

3300 East Palm Valley Boulevard. The park runs along the corridor east of central Round Rock, with Dell Diamond at 3400 East Palm Valley immediately adjacent.

Parking is distributed across several lots serving different parts of the site, which is a mercy on busy days. The disc golf lot across the lake is the least contested.

On event days, arrive early or park at the far end and walk. Twenty-five baseball diamonds generate a lot of vehicles.

Combine it with a donut run. Round Rock Donuts at 106 W. Liberty Avenue has been trading since 1926 and is a few minutes away.

Why a city of 142,000 has a park this size

It is a fair question, and the answer explains a lot about Round Rock.

The city had a population of 142,053 as of December 2025, in a Williamson County of roughly 752,800 people that is among the fastest-growing counties in the United States — adding more than 25,000 residents between 2023 and 2024 alone.

Cities growing at that rate face a choice: buy and build parkland early while it is still affordable, or spend decades regretting it. Round Rock bought early and kept investing, and the 2023 bond is a continuation of that rather than a change of direction.

The sports-tourism return is the second half of the logic. A park that draws national tournaments fills hotels and restaurants across the city, which is why the investment keeps getting approved.

The park across the seasons

Central Texas has a real summer, and it shapes how this park is used.

Spring and autumn are the best conditions: comfortable, and the peak of the tournament calendar, so plan around the crowds rather than the weather.

Summer is hot enough that midday use of the open fields is genuinely unwise. This is when Rock’N River earns its place, and when early mornings and evenings are the only sensible times for the trails.

Winter is mild by most standards and the park stays perfectly usable — quiet trails, empty disc golf, and no queue for anything.

If you want the park at its calmest and most pleasant, a clear winter weekday morning is the answer almost nobody gives.
