About us

San Marcos sits perfectly between Austin and San Antonio, and is home to endless outdoor adventures; but, few are aware of the city's beautiful underwater landscape! Sunfish, blue tilapia, crayfish, and red eared slider turtles are just a few of many that inhabit the San Marcos River. Let us guide you through this beautiful underwater landscape, and help you discover Texas's best hidden adventure.

Our snorkel tours cover a calm, spring-fed, crystal clear stretch of the San Marcos River. The water is so pristine you won't believe an experience like this exists in Central Texas. Bring a date, your family, or a friend, and come have a blast!

+ What's the best time to book a tour?

We highly, highly, HIGHLY reccommend booking the earliest tour time available on the day you want. Later tour times usually mean a more crowded river. Any time we have available will be an amazing experience, but we can't reccomend enough to book an early tour time.
