Adventure brief
Sun, Sound, and a 150‑HP Push: Exploring Lake LBJ Aboard a 13‑Person South Bay Tritoon
Set sail on Lake LBJ’s wide, constant‑level waters in the Texas Hill Country aboard a roomy 13‑person, 24‑foot South Bay Tritoon. With robust engines, shade from a Bimini top, and gear for towing and floating, this rental is built for cruising, anchoring, and easy days of play on nearly 6,534 acres of lake.
Float across Lake LBJ aboard the 13-person 24 ft South Bay Tritoon, a roomy, high-powered option for groups who want to explore the Highland Lakes from Granite Shoals, Texas. Lake LBJ sits in the heart of Texas Hill Country, a constant-level reservoir stretching over 6,500 acres with deep channels and limestone bluffs that reward slow cruises and secluded anchorages. This Tritoon brings muscle and amenities: a 150 HP Mercury motor, towing bar for inflatables, Bimini shade, and a sound system that keeps the party rolling between coves.
Plan a day that blends cruising, swimming, and shoreline exploration. Power out to wide-open water for wake sports or slide into quieter arms of the lake to drop anchor and swim from the swim platform. The boat’s shallow draft and stable three-tube design make it forgiving near rocky shoals and over submerged terraces common along Lake LBJ’s shoreline. Granite outcrops and cedar-covered hills frame many coves; you’ll see stretches of limestone ledge that break to sandy fingers where families like to pull up and spread out.
Logistics are straightforward: highlandlakesboatrentals operates from Granite Shoals, roughly an hour from either Austin or San Antonio, making the Tritoon an accessible day trip or weekend centerpiece. Rentals include modern safety gear and paddling options, and operators keep their fleet of new tritoons, towables, and paddling equipment ready for easy loading. Note the rental policy: operators require renters to be 21 to rent or operate the vessel.
Why book this trip? It’s a versatile platform: large groups fit comfortably, non-swimmers get extra stability, and the 150 HP engine gives confident acceleration for towing toys or reaching a favorite cove. For families it’s practical; for groups chasing sun and social time it’s fun. The boat’s design suits Lake LBJ’s geological personality — long arms, deep channels, and stone-lined points — so you can enjoy both cruising speed and slow-anchored afternoons.
Lake LBJ is a constant-level impoundment of about 6,534 acres with spots nearly 100 feet deep, so you’ll find steady water for tubing and sheltered coves for swimming. Pack reef-safe sunscreen, extra drinking water, and an auxiliary anchor; check fuel and life jackets before you go. For longer days bring a cooler and picnic, and scout public shoreline access for late-afternoon gatherings. Also bring a spare tow rope.
