Experience the San Marcos River at night with translucent LED kayaks on this guided glow tour — perfect for beginners and adventure lovers alike.
If you’re looking for a unique way to experience the Texas outdoors after sunset, the Crystal Kayak Glow Tour offers a striking blend of nature, light, and gentle adventure. This guided outing takes you along the San Marcos River in a translucent kayak illuminated with colorful LED lights, revealing the aquatic world beneath you in a completely new light—literally.
What makes this tour stand out? First, the visual spectacle of the glowing water and underwater illuminations creates a surreal experience—perfect for capturing memorable photos or simply soaking in the scene. Second, the knowledgeable guides help make the journey accessible and educational, whether you’re a seasoned paddler or a first-timer.
One potential consideration is that the tour is relatively short—about 75 to 90 minutes—so if you’re craving a full evening’s adventure, you might want to combine it with other activities around San Marcos. This experience suits nature lovers, curious travelers, couples on a date night, and anyone eager for a night-time adventure with a touch of magic.


The San Marcos River is a natural wonder, with its water bubbling up from the Edwards Aquifer through hundreds of spring openings. This makes it a refreshing and lively environment—perfect for daytime activities like swimming or tubing. At night, however, the river takes on a completely different personality, especially when illuminated by the special underwater LED lights that adorn each translucent kayak.

The main highlight is paddling along the San Marcos River, which emerges from springs that feed into Spring Lake. The water is clear and inviting during the day, but at night, the LED lights transform the environment, creating a vibrant, glowing pathway beneath your kayak.
During the paddle, guides provide insights into the local wildlife, scenery, and history—making the quiet glide not just pretty but also educational. You might see the aquatic life that is normally hidden during daylight, and your guide will share stories about the river’s importance to local ecology and history.
The lights are adjustable, offering seven different colors and settings, allowing you to customize your experience.
