10 Overcrowded Colorado Lakes That Underwhelm

Colorado’s stunning mountain lakes draw thousands of visitors each summer seeking outdoor adventures and breathtaking views. But not every alpine lake lives up to the Instagram hype. I’ve spent countless weekends exploring Colorado’s waters, and frankly, some popular spots leave much to be desired. Here’s my honest take on lakes that might have you reconsidering your weekend plans.

1. Grand Lake: Not So Grand After All

Whoever named this body of water must have had a wicked sense of humor. Despite being Colorado’s largest natural lake, Grand Lake feels more like a crowded swimming pool on summer weekends.

Motorboats zip across the water at alarming speeds while jet skis create waves that could rival the ocean. Finding parking requires the patience of a saint and the skills of a Formula 1 driver. The shoreline? Packed with tourists who seem determined to outdo each other with massive coolers and blaring portable speakers.

Though the surrounding mountains provide a decent backdrop, the constant noise pollution and floating debris from careless visitors make this lake anything but the serene mountain escape promised in brochures.

2. Lake Dillon: A Reservoir of Disappointment

Nestled between popular ski towns, Lake Dillon tricks visitors with its promising location. However, this massive reservoir offers a shockingly cold swimming experience that numbs both body and enthusiasm.

Parking lots overflow by 9 AM, forcing latecomers to walk nearly a mile just to reach the water. The so-called beaches are primarily mud and rocks that somehow find their way into every sandwich and bag. Families struggle to claim tiny patches of shoreline while watching rental boats cruise by at premium prices.

While the surrounding peaks look impressive in photos, the reality includes constant traffic noise from I-70 and the distinct smell of sunscreen mixed with boat fuel. Honestly, the best view of Dillon might be from your car as you drive past it to somewhere else.

3. Chatfield Reservoir: Suburban Splash Zone Chaos

Located just outside Denver, Chatfield should come with a warning: “May cause extreme frustration.” The entrance lines on summer weekends can stretch for over an hour, making you question your life choices before you even see water.

Though massive in size, finding space feels like playing a real-life game of Tetris as families stake claims with elaborate tent setups and boundary-pushing blanket arrangements. The water itself? Often murky with questionable floating objects that I prefer not to identify.

Forget peaceful paddleboarding – you’ll spend most of your time avoiding collision with novice boaters who apparently received their licenses from cereal boxes. The lakeside facilities remain perpetually overwhelmed, with bathroom lines rivaling those of popular concert venues. Save yourself the headache and find a backyard kiddie pool instead.

4. Cherry Creek Reservoir: Urban Letdown

Smack in Denver’s backyard, Cherry Creek Reservoir promises convenient water recreation but delivers an experience more akin to an overcrowded public pool – minus the chlorine that might actually improve the water quality.

Weekends transform this reservoir into a chaotic scene where finding beach space requires early arrival and territorial instincts. The water temperature fluctuates between surprisingly cold and uncomfortably warm in shallow areas. Algae blooms regularly close sections during peak summer months, leaving visitors staring longingly at water they can’t enter.

For the privilege of this mediocre experience, you’ll pay entrance fees that seem increasingly unjustified given the crowds and conditions. The nearby airport flight path ensures your peaceful lake day includes regular reminders of places you’d rather be visiting instead.

5. Boulder Reservoir: Rocky Mountain Mediocrity

How Boulder manages to make a reservoir simultaneously pretentious and disappointing remains a mystery worthy of scientific study. The entrance fee feels like highway robbery considering what awaits inside.

First-time visitors might be shocked by the lack of shade – bringing your own umbrella becomes essential unless you enjoy resembling a lobster by day’s end. The swimming area shrinks each year while the number of visitors grows, creating a mathematical equation that equals discomfort. Fitness enthusiasts circle the water’s edge in expensive athletic wear, somehow making relaxation feel competitive.

Though the Flatirons provide a picturesque backdrop, they serve mainly as a reminder of better outdoor experiences available nearby. The concession stand charges prices that would make airport vendors blush, completing this underwhelming experience that somehow maintains popularity through collective delusion.

6. Horsetooth Reservoir: Fort Collins’ False Promise

If disappointment had a geographic location, Horsetooth Reservoir would be its coordinates. This lengthy reservoir near Fort Collins attracts crowds who apparently haven’t received the memo about its limitations.

The rocky shores make barefoot walking an exercise in pain tolerance, while finding flat ground for setting up camp requires engineering skills. Water levels fluctuate dramatically, sometimes revealing shorelines that resemble lunar landscapes more than beaches. College students flock here in droves, transforming quiet coves into impromptu party zones with questionable hygiene practices.

Boat rental prices would make more sense if they included ownership papers, and the constant wind whips up waves that challenge even experienced paddleboarders. Meanwhile, the reservoir’s long, narrow shape means you’re never far from someone else’s music, conversation, or cooking smells – privacy is merely theoretical at Horsetooth.

7. Eleven Mile Reservoir: The Long Drive to Letdown

After driving what feels like eleven hundred miles on increasingly questionable roads, you’ll arrive at Eleven Mile Reservoir with high expectations. Unfortunately, reality rarely meets them.

Known for fishing, this massive reservoir primarily attracts anglers who stake out prime spots before sunrise, leaving casual visitors with subpar locations. The wind here deserves its own weather classification – “potentially airborne” – making swimming and paddling exercises in futility. Campsites offer minimal privacy, creating the strange experience of feeling simultaneously isolated from civilization yet uncomfortably close to strangers.

Though marketed as a wilderness experience, the reservoir’s shoreline often resembles a parking lot for fishing boats and RVs. The water’s murky appearance raises questions about what lurks beneath, while the perpetually cold temperature ensures brief, gasping swimming attempts rather than leisurely floating.

8. Blue Mesa Reservoir: The Long Haul Letdown

Colorado’s largest body of water manages to be simultaneously too big and too crowded – an impressive paradox. The three-hour drive from Denver builds anticipation that quickly deflates upon arrival.

Finding beaches without boat traffic zooming dangerously close requires insider knowledge or exceptional luck. The water temperature hovers somewhere between “instant hypothermia” and “slightly numbing,” making swimming more endurance sport than recreation. Seasonal water level drops create vast mud flats that transform pleasant walks into sinking adventures.

Despite its size, popular areas become surprisingly cramped during summer months. Campsites fill months in advance, leaving spontaneous visitors with few options besides overpriced lodging. For the effort required to reach it, Blue Mesa delivers an experience remarkably similar to reservoirs much closer to the Front Range – minus the convenience.

9. Pueblo Reservoir: Southern Colorado’s Sweltering Disappointment

Visiting Pueblo Reservoir in summer feels like volunteering for a slow-roasting experiment. The shadeless landscape amplifies temperatures that regularly exceed 100 degrees, creating a uniquely uncomfortable experience.

Finding water access without encountering broken glass or questionable debris requires detective skills. The reservoir’s fluctuating water levels create a ring of mud that visitors must traverse – wearing flip-flops here qualifies as an extreme sport. Weekends transform the shoreline into a patchwork of portable speakers competing for acoustic dominance.

Though promoted for water sports, the frequent presence of blue-green algae adds an element of biological roulette to swimming plans. The facilities appear trapped in a time warp from several decades past, with maintenance apparently considered optional. When a gas station splash pad starts looking like a superior alternative, you know a lake has failed its basic purpose.

10. Standley Lake: Westminster’s Watery Letdown

Sandwiched between suburban sprawl, Standley Lake somehow manages to combine the worst aspects of both urban and natural environments. The entrance fee feels particularly insulting given the limitations awaiting inside.

Swimming? Prohibited due to it being a drinking water source – though this doesn’t stop the lake from hosting algae blooms and waterfowl that seem unaware of proper sanitation practices. Boating restrictions create traffic jams on the water that mirror Denver’s rush hour congestion. The designated recreation areas concentrate visitors into spaces that quickly become uncomfortably intimate with strangers.

While offering decent views of the Front Range, these same mountains serve as constant reminders of superior lakes just an hour’s drive away. The paved pathways and manufactured beach areas create an experience that feels more like visiting a water-themed mall than connecting with nature.
