Diamante Days at Horsetooth: A Luxurious Pontoon Escape on Colorado’s Reservoir

Out on Horsetooth Reservoir, just southwest of Fort Collins, Colorado, the Viaggio Diamante 23S turns a day on the water into a comfortable, all-purpose escape. Operated as an on-the-water or take-and-go rental, this 11-person pontoon pairs a 250HP Mercury four-stroke with a long, configurable deck: swingback lounger that becomes a sunpad, a Pro Series ski tow bar, Fish Finder with down and side imaging, RGB lighting, and an optional built-in BBQ. The reservoir’s oak-streaked shore and sandstone hogback—Horsetooth Rock visible from many coves—provide a dramatic backdrop whether you’re cruising, fishing, or towing a tube.

Boarding occurs at the South Bay boat ramp or from on-water slips at Boyd Lake Marina depending on booking; the company holds captain-led scenic tours for groups or self-captained on-the-water rentals for boater-savvy visitors. With 6- and 8-hour options (and multi-day take-and-go packages), the Diamante suits swimmers, anglers using the onboard fishfinder, families wanting a shaded bimini and floatable table, and watersports enthusiasts who want surf and wake setups. Extras like floating lake mats, wakeboards, and a towable tube turn a calm lake afternoon into an action-packed outing.

Why this service stands out in northern Colorado is scale and flexibility: few rentals in the Fort Collins area offer a performance 250HP motor plus luxuries like a powered bimini, Rockford Fosgate audio, and optional grill in a single package. That makes the Diamante equally at home carving open water, anchoring in a quiet cove for lunch, or staging a sunset cruise where Horsetooth Rock and the jagged hogback ridge drop into long reflections on the reservoir.

Practical notes: renters must be 21+ with ID, operators 16+ (with boating certification for under-18 operators), and a credit card is held for damage deposit. Bring sun protection, water, and towels; consider the BBQ and floating mat extras for longer trips. The company departs from recognizable local ramps and provides both self-captain and captain-led choices—ideal for groups who want both independence and the ease of a guided outing.

Expect changing winds off the foothills that can build steep, choppy wakes near dam and in narrow coves; captains screen for that and will recommend sheltered anchorages for swimmers and less experienced riders. Fishing is productive for bass and trout along submerged rock shelves near the hogback; bring a light-action rod and polarized lenses to read structure. Late summer sunsets throw long light across the water while spring runoff raises water levels and brings clearer views of exposed cliffs.

For anyone visiting Fort Collins who wants a waterborne perspective of the foothills, the Diamante 23S is a high-comfort, multi-purpose way to experience Horsetooth’s cliffs, coves, and open water—whether you’re chasing a wake, a trophy catch, or a quiet afternoon on a floatable mat.
