Established in 1984, this small national park lies just south of Lake Naivasha and about 90km north-west of Nairobi.
Alarming as the name might sound, don't be put off - the park itself is rich and stunning and should form a most rewarding part of a trip to Kenya.
So, how did it get such an intimidating name? Explorers Fischer and Thomson gave this name after discovering this area's dramatic landscape; reddish cliffs with narrow gorges spewing steam; hot springs and geysers; swirls of obsidian - a glossy, black igneous rock formed from cooled molten lava; and all against the backdrop of grassy green savannah.
What these explorers didn't know at the time was that this land was where much human life originated - it was once a tributary to a prehistoric lake which fed our ancestors, the early humans of the Rift Valley.
As if that wasn't enough, the park is also recognised as an important habitat for one of the world's rarest raptors - the Lammergeyer, or Bearded Vulture.
These huge carrion birds can grow wingspans of up to 3 metres (10 feet), and has the singular habit of dropping large bones from a great height to crack them open and feast on the marrow within.
So, better mind your head in Hell's Gate! Other bird species found here include the magnificent, hyrax-hunting Verreaux's Eagle, and the soaring Augur Buzzard.
Mervyn Carnelly's Raptor Hide is a great place to view these impressive creatures up close.
Other common animals include the African Buffalo, zebra, eland, hartebeest and Thomson's gazelle.
And don't forget, Hell's Gate is one place where you might just come face to face with one of these creatures! The lack of predators means you can take walking, cycling or even horse-riding safaris, so you're not just confined to a vehicle.
Nothing heightens the senses like the steady gaze of a groups of buffalo...
So, what to do after visiting the origins of human life, watching a hunched Lammergeyer at close range, and taking a stroll amongst the gazelle and giraffe? Well, you could visit the Oloor Karia Masai Cultural Centre, where you'll see singing, dancing and jewellery-making demonstrations by local Masai people.
This centre isn't far from Fischer's Tower, also known as the Stone Lady.
Legend has it that a young Masai woman was sent from her home to marry against her will.
She was warned never to turn back to gaze upon her old home, but of course sadness overwhelmed her, and she felt compelled to glance back to her beloved home one last time.
As she did, she turned immediately to stone, and there she remains to this day.
There are two main gates to access Hell's Gate National Park - Elsa Gate and Olkaria Gate - and though there isn't any accommodation within the park itself, there's plenty of accommodation nearby in the vicinity of Lake Naivasha.
Alternatively, your tour operator should be able to include an en route day trip to Hell's Gate as part of your package.
