The African Spiral Horn Slam is one of the most iconic and biologically diverse achievements in big game hunting. This elite slam challenges hunters to ethically pursue a collection of Africa’s most elusive and beautifully adapted antelope species—each recognized for their characteristic spiral-horned trophies, wariness, and highly specific habitats. Unlike the African Big Five, which is defined by size and danger, this slam celebrates precision, patience, and an intimate understanding of regional ecosystems.
Completing the spiral horn slam requires hunters to travel across various biomes—dense rainforests, open savannahs, riverine woodlands, and mountainous terrain. With species ranging from the massive Lord Derby eland to the elusive forest-dwelling bongo and sitatunga, this journey is as much a test of adaptability and endurance as it is a tribute to African biodiversity.
With the SlamHunt App, hunters can now track their spiral horn species, log encounters, and connect with outfitters and other slam participants who share the same ambition.
Pursuing the African Spiral Horn Slam requires strategic planning across multiple ecological zones and countries. From East Africa’s acacia-dotted hillsides to the swampy lowlands of Central Africa, each region offers a distinct terrain, climate, and hunting approach. These hunts often involve coordination with specialized outfitters and guides familiar with local wildlife movement patterns, regulations, and logistical challenges.
Certain areas are only accessible seasonally, and others may require long-distance fly-ins, mobile camps, or tracking on foot for several days. Planning ahead to accommodate different elevations, vegetation types, and political regulations is crucial to safely and successfully harvesting all the species in this slam.
The African Spiral Horn Slam generally includes the following recognized species:
Greater Kudu: Found across Eastern and Southern Africa, this spiral-horned antelope thrives in woodland-savannah mosaics. Known for its towering spiral horns and elusive behavior, the greater kudu is often sought in fair chase hunts. Its ability to vanish into cover makes it a favorite in guided spiral horn expeditions.
Lesser Kudu: Native to dry bushlands of northeastern Africa, this elegant species demands precision and stealth. The lesser kudu’s rapid flight response and dense habitat make it one of the most challenging spiral horn species to hunt ethically.
Nyala: Inhabiting riverine woodlands and forest edges of South Africa and Mozambique, the nyala is prized for its distinct markings and timid nature. This trophy-class antelope prefers dense vegetation, rewarding hunters who value patience and strategic positioning.
Mountain Nyala: This rare highland antelope is endemic to the Bale Mountains of Ethiopia. It lives in steep alpine zones and demands multi-day backpack hunts. With extremely limited distribution and legal access, it’s one of the toughest spiral horn trophies to achieve.
Common Eland: As Africa’s largest antelope, the common eland roams open grasslands and light woodlands. Despite its bulk, it’s known for its speed and endurance. Long-range tracking and persistence are key to taking one in open terrain.
Lord Derby Eland: Also called the Giant Eland, this species inhabits remote hunting concessions in Central and Western Africa. Harvesting a mature bull requires logistical planning, local tracking expertise, and significant stamina.
Sitatunga: This swamp-dwelling, semi-aquatic antelope is one of the most difficult spiral horn species to hunt. Found near rivers and wetlands in equatorial Africa, sitatunga hunts often involve boats, blinds, and full waterproof gear.
Bongo: The bongo is a forest-dwelling antelope known for its reddish coat and nocturnal movement. It inhabits dense rainforests and is rarely seen during daylight. Hunting a bongo represents the pinnacle of fair chase spiral horn achievements.
Harnessed Bushbuck: With its wide sub-Saharan range, the bushbuck is often the first spiral horn species taken. It adapts to a variety of habitats and requires keen awareness due to its unpredictable behavior and strong territorial instincts

Most organizations that acknowledge the African Spiral Horn Slam require clear photographic evidence, including visible horns, hunter identity, date, and location. Additionally, confirmation by a licensed PH or outfitter is often expected, along with species identification. Optional elements like CITES documentation may be requested for restricted species.
You must verify that the concession or territory is legally registered for the species in question, with active quotas issued by the regional wildlife authority. A professional outfitter should provide copies of permits, quota status, and proof of legal operating status. This is especially important when hunting in areas with community conservancy models
Yes, some expeditions are structured to target 2–4 species within the same region, such as kudu, nyala, and bushbuck in Southern Africa. However, rarer species like bongo or mountain nyala usually require specialized trips. Combining species depends on geography, outfitter access, and seasonal overlaps in hunting regulations
Conservation Impact of the African Spiral Horn Slam
The African Spiral Horn Slam goes beyond the collection of rare trophies—it represents a deep engagement with some of Africa’s most complex wildlife systems. Hunters who take on this challenge often invest in long-term outfitter partnerships, regulatory compliance, and travel into remote habitats, indirectly supporting broader conservation infrastructure and local economies tied to ethical hunting
Participating in the African Spiral Horn Slam contributes more than just personal achievement—it plays an active role in funding and reinforcing sustainable wildlife programs across the continent. Many of the species in this slam inhabit sensitive ecosystems, and the revenue generated through tag fees, outfitter licensing, and trophy permits helps maintain those environments.
Funds from legal spiral horn hunts are often reinvested in:
• Anti-poaching patrols in remote concessions
• Population tracking for rare species like bongo and mountain nyala
• Habitat corridor preservation in transboundary areas
• Local training for wildlife monitors and conservation rangers
Because many spiral-horned antelope live in regions with limited infrastructure, hunting concessions become part of the conservation model—providing controlled human access, ongoing species data, and funding that would otherwise be unavailable
In countries like Cameroon, Ethiopia, Mozambique, and Namibia, spiral horn hunts often take place within community-managed reserves. These models ensure that local populations benefit directly from sustainable hunting, through employment, meat distribution, and revenue-sharing agreements.
The presence of hunters—under ethical and legal guidelines—also reduces illegal bushmeat poaching by establishing oversight, investing in local services, and creating economic incentives to protect game populations
Numerous regional and international organizations support spiral horn antelope conservation by:
• Funding scientific research and ecosystem studies
• Hosting tag raffles to raise conservation dollars
