Experience

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 ofthefirst 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 + Drink

Dos Gatos Kolache Bakery
A go-to breakfast spot for locals, Dos Gatos serves up Czech kolaches (aka fruit-filled) and Texas kolaches with meat and cheese. Figi here — I like to order one of each, usually pepperoni + swiss and blueberry cream.

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.

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.

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.

Senza Maeso
A boutique tasting room that borders San Marcos and Wimberley, this bar serves its eponymous Senza Maeso hybrid spirit, which is made with South American cape gooseberry and steeped with herbs.

Wake the Dead Coffee House
With a "funky Tim Burton-esque" interior stacked with local art + a tranquil back garden, this coffee shop has been keeping San Marcos caffeinated for nearly 20 years.

Zelicks Icehouse
Grab a local beer and a pulled pork sandwich to enjoy in this beer garden, which stays open late and is just a stone's throw away from San Marcos's famous Square.

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.
