The rules
The NCAA's Crater Rules, in Plain English
Single-entry permits, a 3,500 kg vehicle limit, a mandatory guide and a five-vehicle cap at any sighting. What the authority actually requires.

The permit is single entry, and that shapes your whole trip
This is the rule that quietly determines where you sleep and what your days look like. The NCAA states that all permits, including crater service, are single entry, and that a permit once issued is valid for one entry within 24 hours only. There is no in-and-out. If you stay outside the conservation area and drive in on two consecutive days, you are buying two entries, not one. Fees must be paid within 24 hours of entry. Any itinerary that assumes you can pop out for lunch and come back is built on a misunderstanding, and it is an expensive one to discover at the gate.
You cannot take just any vehicle down
Descent to the crater floor is restricted to four-wheel-drive vehicles of up to 3,500 kilograms tare weight, with an exception for authorised trucks carrying organised groups. That weight limit is a real constraint and not a formality — it rules out a good deal of what would otherwise be capable transport. Note the scope carefully: the restriction applies to the crater floor specifically. For the wider conservation area, the NCAA's own guidance is that vehicles other than four-wheel drives can access the area, although it advises four-wheel drive in the rainy season to avoid getting stuck in the mud.
A guide in the vehicle is not optional
The NCAA's wording is unambiguous: a licensed guide or an official NCAA guide must accompany all crater visitors. This is the single most important rule for anyone planning to arrive independently, because it means that even a correctly specified private 4x4 cannot simply drive down. Separately, all vehicles operating within the conservation area other than private and government vehicles must be registered company vehicles holding a valid TALA licence under the Tourism Act 2008. What counts as a private vehicle for a rental is not defined by the NCAA, so confirm your specific situation with them or with the rental company rather than assuming.
Behaviour rules with real teeth
Several rules exist to stop the crater being loved to death, and they are enforced. Off-road driving is prohibited unless authorised by the Conservation Commissioner. Visitors must stay in their vehicles at all times except in designated areas — there is no getting out for a photograph. Congestion around a kill or a sighting is prohibited, with a maximum of five vehicles permitted and a minimum distance of 25 metres from the animals. Plastic bags are banned throughout the conservation area, pets are forbidden, and photographing local people is prohibited outside the designated cultural bomas.
Timings, and one sentence to check for yourself
Driving anywhere in the conservation area is permitted between 06:00 and 18:00, with speed limits of 50 kph generally and 25 kph at the craters. On descent timing, the NCAA's published guidance reads: “Crater descent gates close at 16:00 hours and close at 18:00 hours.” That sentence is garbled as published, and the most plausible reading is that descent closes at 16:00 and you must be off the floor by 18:00 — but because we cannot verify that reading, we quote it rather than paraphrase it. Confirm the current descent cut-off with the NCAA or your operator before planning a late afternoon.
