 Just made a last minute booking for a quick family getaway and wondering if anyone could advise somewhere family friendly that won't be inundated with walkers (if that is even possible with current stay-cations). 

The only times I've been to the Brecon Beacons has been to beast myself training for bigger mountains so just Pen y Fan and surrounds. 

Thanks,

Derry

My kids liked to walk out and find the plane wrecks... Google them... some have quite a bit of wreckage left...

Any of the walks other than Self-Y-Fan should be fine especially on a week day. Avoid that entire road and parking area and hill and you’ll see 1-3 pairs of walkers on an average walk. 
 

Last 2 time’s I went to BB I parked in a lay-by to the north of fan-y-big and walked up and then anti clockwise across cribbyn and back to the car and rarely see anyone else. 

Take them along Cat’s Back Ridge (Black Hill), above the Olchon Valley.  A lovely and generally quite day out, keep an eye out for the Witches Tree.

I'd walk round Craig Cerrig Gleisiad from the A470 a couple of kms north of Storey Arms.

Chartists Cave from either Trefil or the Llangynidr road (it can be fun finding the actual cave as well!)

There's a big parking area at Penwyllt by the cavers' terrace and you can walk into the nature reserve from there - limestone pavements, plus a section of the Beacons Way.

this is my local walk. Very narrow lanes to get to the car park, but a very pleasant circular walk.

I like the Black Mountains horse-shoe. I start in Llanbedr (1m NW of Crickhowell). Go up to `Table Mountain' hillfort, then wiggle northwards up along the ridgeline through Pen Cerrig-calch and Pen Allt-mawr all the way up to Waun Fach, then back down S/SE to Pen Gadair Fawr and follow that ridgeline back to Llanbedr. You can shorten it by cutting back at the shoulder between Mynydd Llysiau and Pen Trumau `on the way up'. 

Alternatively, a bit west of the Beacons, is the Black Mountain. Start at Glyntawe and head N/NW up the prow in front of you. And either go up/down the way you came, or go up, and follow the `edge' right round and come down by the two little lakes (Llyn y Fan Fach and Llyn y Fan Fawr) and then back down the side of the hill. 

Brilliant. Thanks everyone, that's loads to look in to. Cheers
