Float the San Marcos River
Grab your sunscreen and get ready for this beloved local pastime. Head to Lions Club, Don’s Fish Camp, or Texas State Tubes to rent a tube, grab your drink of choice (in a reusable container), and strap in for a few hours on the water. Fun fact: the San Marcos River stays at a cool 72º year-round.

Visit Wonder World Cave & Adventure Park
This unique theme park (which boasts the title of the first commercially opened show cave in Texas) has visitors traipsing through rock formations and gazing at fossils on guided tours. When you emerge, head to the anti-gravity house and take a train ride through the wildlife park.

Take a glass-bottom boat tour
See some of San Marcos’ aquatic beauty in a 30 or 45-minute guided boat ride that allows you to see the river from the top down. The tours have been running in San Marcos since 1945 and run daily.

Eat

The Root Cellar Cafe
Have a seat in this underground dining room, which will soon celebrate 20 years in business. The Root Cellar Cafe offers breakfast, lunch, and dinner (and makes its own baked goods), serving upscale American fare. Psst — don’t miss the attached UpRoot speakeasy.

Rhea’s Ice Cream
This shop sells the (self-proclaimed) best small-batch ice cream in the world. With unique flavors — including Circus Animal cookie, vegan avocado coconut, Big Red, and goat cheese with raspberry jam — this spot is perfect to visit after a long day in the sun.

Grins Restaurant
Frequented by students and locals alike since 1975, Grins is famous for its legendary happy hour specials (like $1 margaritas) and Tex-Mex fare. Pro tip: sit outside because Grins is located atop a hill and offers breathtaking views of Texas State’s campus.

Stay

Crystal River Inn
Stay a hop, skip, and a jump from Downtown San Marcos at this eight-room, 1880s Victorian estate and event venue.

Mermaid Retreat
An “enchanting” stay, the Mermaid Retreat provides space for six, a covered patio, and a fire pit for chilly nights.

Palmer’s Guest House
This Vrbo in the center of town has all the amenities, including a private patio and a hot tub for ~$92 per night.

Wait a minute, Austinites. Before you head out the door, find the cheapest places to fill up your gas tank and stock up on road trip snacks from Buc-ee’s. Also, bookmark this map so you have no trouble finding all of our recommendations while visiting San Marcos.
