Is the Four Waterfalls walk free once I have parked?

The trail itself is a waymarked walk, not a castle ticket. You pay the car park. Gwaun Hepste is £6 a car. You can also start from Cwm Porth — check that board too.

Is this the same parking rule as Pen y Fan?

No. Four Waterfalls and Pen y Fan are different car parks, different operators, and different prices. See the Pen y Fan parking journal.

Four Waterfalls: pay to park, do not swim

Q: How long is the trail?

Natural Resources Wales describes the Four Falls Trail as about 5 miles, graded strenuous, about 3 to 4 hours. The links to each fall are narrower and stepped.

The Four Falls Trail is a waymarked walk in Waterfall Country, Bannau Brycheiniog. It is not a castle ticket. You pay to park. The drops are unguarded. Do not swim.

The car park

Natural Resources Wales runs Gwaun Hepste, the usual start. Checked on their page on 8 September 2026:

Car — £6.
Minibus — £7.
Card only. There is no cash machine on site.
No overnight stays.

You can also start from Cwm Porth. That is a different car park. Read that board too. Neither price is the Pen y Fan tariff. See Pen y Fan parking is not Pen y Pass.

The walk

NRW describes the Four Falls Trail as about 5 miles, graded strenuous, about 3 to 4 hours. The links to each fall are narrower, stepped, and slippery after rain. The main trail is not the same as standing under a fall.

Do not swim. The water is cold, the rocks are smooth, and there is no lifeguard. A photograph from a dry week is not a measure of the river today.

Nearest town

The walk sits north of the Vale, often reached via Pontneddfechan or Ystradfellte. The town door on this site is the Brecon guide. It is a drive from Brecon, not a stroll from the high street. Allow that before you promise a short stop.

What to take

Card for the machine. Shoes with grip. A plan that does not depend on a phone signal at the falls. If the board says the path to a fall is closed, use the main trail. The price of the car park is the published charge. It is not a guide fee, and it does not include a swim.

Which start, and what not to do

Gwaun Hepste and Cwm Porth are different car parks. Pay at the one you use. Do not assume a lay-by on the lane is a free version of the same walk. If the machine will not take the card, you still do not invent a verge.

The paths to the individual falls are the slippery part. Stay on the waymarked line. Do not climb fences to get closer to the drop, and do not swim below it because a photograph looked calm. After rain the river is faster than it looks from the bank.

This is not Pen y Fan, and it is not a Cadw day. The Brecon guide is the nearest town door. Allow the drive from the town before you treat the walk as a short stop. Pay the car park you use, and do not treat a closed side path as a shortcut to the water today.
