Diving atCrazy Horse Sink (United States)
Crazy Horse Sink offers a distinct contrast for divers, transitioning from a wooded, terrestrial landscape into a deep, clear water-filled sinkhole. This site provides access to both cavern and cave environments, presenting a different diving experience from typical open-water sites. Its consistent underwater temperatures remain inviting even as surface air conditions fluctuate seasonally.
Recent updates for Crazy Horse Sink show an air temperature measuring 32.5°C. Overall water conditions reflect the typical seasonal state for United States. Please exercise standard safety precautions before entering the water.
Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Crazy Horse Sink invites exploration of a complex submerged system, transitioning from a wooded surface into intricate underwater topography. Measuring approximately 11 m (35 ft) in diameter, the initial pool features steep slopes at its edges; however, newer dock and stair facilities now ease water entry and exit.
Deeper sections of the connected cave system extend significantly, reaching at least 43 m (140 ft), with reports of some divers encountering depths of 44 m (144 ft) further within these passages. This unique sink contains natural debris such as submerged trees, fallen limbs, and various organic matter.
Additionally, notable horse and cow skeletons rest on the bottom, contributing significantly to its distinct and often eerie character. Its waters connect directly to the extensive Lafayette Blue Cave System, indicating a general westward flow beneath the river, which divers occasionally perceive.
Experienced divers are able to explore a notably spacious cavern section, before the environment eventually constricts into a true cave, strictly requiring appropriate certification for any penetration. A recent training platform further enhances the site's utility, providing a stable, submerged base for skill development and dive preparation across various experience levels.

Best Time to Dive
For divers considering a trip, the consistent underwater environment here makes year-round diving a practical option. Stable underwater temperatures, typically ranging from 23-24°C (74-75°F), provide a comfortable experience regardless of the season. Surface air temperatures, however, exhibit considerable variation. Conditions can range from a cooler 10°C (50°F) in January and February to a warmer 27°C (81°F) during July and August, which impacts surface comfort and gear choices. While rainfall is generally low to moderate, averaging between 1.5-5.7 mm (0.06-0.22 inches) monthly, heavier summer rains from June through August can sometimes introduce a milky layer near the surface. This effect is usually temporary but might slightly reduce immediate surface visibility upon entry. To secure the best underwater visibility, planning dives during weekdays or early mornings is often advisable. Such timing helps to avoid potential siltation from other divers, especially within the more confined sections of the sink. Monitoring local weather forecasts for significant rainfall events can also help optimize dive planning.

Dive Experience & Conditions
Divers often find the water entry at Crazy Horse Sink quite manageable, thanks to the newer dock and stair access. However, transporting gear to the sinkhole itself can be challenging due to steep surrounding terrain. Underwater, the cavern is notably spacious, providing ample room for exploration before transitioning into the more confined cave passages. Visibility is frequently excellent, with reports consistently reaching 30 m (100 ft) or more, even after periods of rain. This clarity can degrade swiftly with improper finning or high diver traffic, as the silt layer is easily disturbed. Water temperatures are remarkably stable, staying around 23-24°C (74-75°F) throughout the year, which is comfortably warm. While largely placid, a minor flow has been observed in specific cave sections, typically between 24-27 m (80-90 ft).
Dive Difficulty & Safety Guidelines
The primary safety concern at Crazy Horse Sink revolves around its easily disturbed silt bottom, which can rapidly reduce visibility if divers do not maintain precise buoyancy and finning techniques. Entanglement hazards exist from the natural organic debris and tree limbs within the sink. Penetrating beyond the designated cavern area into the cave system strictly requires appropriate cave diving certification due to overhead environments and potential restrictions. There is a minor restriction leading into deeper cave sections, which divers should be prepared for. Always carry a reliable primary light source and backup lights, as natural light diminishes quickly at depth. Site operators sometimes require viewing a safety video, and it's important to respect any 'No Trespassing' signage if present, though dedicated access points exist. Be aware of the grave marker located inside the cave, serving as a solemn reminder of past incidents.

Recommended Dive Suit
Because recent water temperature readings are not available for Crazy Horse Sink, the guidance below is based mainly on current air conditions and seasonal expectations. Current surface air temperatures are roughly 33°C (91°F).
Longer-range forecasts show some uncertainty in upcoming temperature trends. A significant temperature drop is forecast; strongly suggest bringing a backup warmer suit option. A neoprene vest or hood can add flexibility if temperatures feel cooler underwater.
Based on regional estimates and current weather, the likely required exposure protection is light protection (dive skin or 3mm shorty). Note that local currents and upwellings can alter this. Many experienced divers adjust their exposure protection depending on the type of dive planned. Divers planning trips later in the week may want to consider bringing a slightly warmer suit.
Due to technical issues with our weather providers, live updates are temporarily delayed. The data above reflects the conditions at the time of the last successful fetch.

Frequently Asked Questions
What is the maximum depth at Crazy Horse Sink?
The main sinkhole typically descends to around 18 m (60 ft). However, the connected cave system extends much deeper, with divers reporting depths of at least 43 m (140 ft), and some reaching 44 m (144 ft) within the cave passages.
What are the typical water temperatures?
Underwater temperatures at Crazy Horse Sink are remarkably consistent throughout the year. Divers can generally expect the water to be between 23-24°C (74-75°F), providing a comfortable diving environment.
Is cave diving certification required?
Open water and cavern diving are permitted in the shallower, lit sections. However, venturing beyond the cavern into the deeper, overhead cave environment strictly requires appropriate cave diving certification due to the complex nature and inherent risks.
How clear is the water usually?
Visibility is frequently excellent, often exceeding 30 m (100 ft) in optimal conditions. Be aware that the bottom is silty and can quickly reduce visibility if disturbed by improper finning or high diver traffic, especially in confined areas.
Are there any specific entry or exit challenges?
The site benefits from newer docks and stairs, making water entry and exit relatively easy. However, accessing the sinkhole area itself can involve navigating steep terrain, which might make hauling heavy dive gear challenging.
What marine life can I expect to see?
