The park is open daily, while the office is open daily from 8:30 a.m. to 4:30 p.m. Keep the office hours in mind if you plan to ask staff about conditions or activities. Park hours, fees and availability can change; check the official site before you go.

A Flexible Park-Day Outline
A good park day can start with a choice between the river and trails, then leave room to adjust your plans once you know the conditions. The park has two miles of frontage along the spring-fed South Llano River, where you can swim, float, paddle or fish.
If you’re planning to paddle, allow for a float that may take two to four hours. The park section of the South Llano Paddling Trail is part of a 6.3-mile trail, and the estimated float time depends on water level, flow rate and wind speed.
For a land-based outing, choose from 22.7 miles of trails ranging from easy to difficult. They cross river bottoms, steep ridges and wooded areas, so you can pick a route to suit the kind of walk you have in mind. The park was formerly a working ranch.
Birdwatching can fit alongside a walk or a quieter break in the day. The park has four bird blinds, and more than 250 bird species have been recorded there over the years. Ranger programs on nature and park history run year-round; check TPWD’s events calendar for the schedule.

Choosing Activities Around Current Conditions
Choose river activities only after checking conditions, and keep the trail and wildlife options in mind as alternatives. The river’s level, flow and wind can affect paddling time, so use current park guidance when deciding whether a float fits your day.
The park rents tubes, and you may bring your own canoe or kayak. Paddlers have one designated place in the park to park and put in. Ask park staff about current arrangements before relying on a particular river plan.
You don’t need a fishing license to fish within park boundaries. If you need equipment, ask headquarters about borrowing fishing gear.
For a quiet wildlife stop, use one of the four bird blinds. Rio Grande turkeys roost at the park from October 1 through March 31; during those months, the day-use area is open only from 10 a.m. to 3 p.m. to avoid disturbing the roost.
South Llano River State Park is also an International Dark Sky Park. Stargazing after hours carries a night activity fee, so confirm the current arrangements with the park if you want to include it.

Getting Back to Junction
Plan your return around the activities you choose and the park’s operating guidance. If you spend much of the day on a float, remember that the approximate paddling time is two to four hours and varies with water level, flow rate and wind speed.
Before leaving, make sure you have time to return to Junction and check any arrangements you need for your chosen activity. If you’re staying in Junction, the park is about a 15-minute drive from this motel in Junction.
What to Confirm with the Park
Confirm current access, activity conditions and any scheduled programs with TPWD before setting out. That check is especially useful if your plans depend on paddling, after-hours stargazing or a particular park program.
For paddling, ask about river conditions and the designated put-in. For a ranger program, check the TPWD events calendar. If you plan to use the day-use area during the turkey roosting months, keep its 10 a.m. to 3 p.m. hours in mind.
Also confirm current day-use availability and fees, since the park often reaches capacity and recommends reserving passes. The office is open daily from 8:30 a.m. to 4:30 p.m.
