No camping allowed at the castle. There is a good campsite nearby at Vale Cruccis (remains of an old Abbey) and lots of accommodation in and around LLangollen.

Definitely not!

path gets very steep and there are slippy rock slopes near the top. not worth the risk.

No fee, just a good hike, all uphill. I corrected Google Maps location and hopefully they made an adjustment. My phone showed it at the bottom of the hill about 1/2 mile from Main Street. It is atop the mountain. Took about an hour going up I believe. Beautiful view of the valley and Llangollen.

There are several routes up so you can either park in the town and head over the bridge and follow the signs (quite lengthy), or do like I did and drive along the A542 (Horseshoe Pass) and take the first right after the Llangollen Pavillion (Eisteddfod Showground) and head for the Panorama Rocks. Quite difficult to describe if you're not familiar with the area so I suggest you check a map. This is probably the shortest route up if you are carrying heavy items. Good luck, hope all goes well and you get good weather.

Thanks everyone. I parked in the short stay car park with toilets, near the tourist information centre.£1 for 4 hours. I walked over the river bridge towards the canal boats ride. Passed the boat ride cafe turned left over the canal bridge to the tiny steps. It took me 40 mins to go up to the castle ruins with my 5 year old and 20 easy mins to come down. We all enjoyed being up. Fantastic views. Picturesque.

I'd go for the pub/public pay and display car park at the bottom just before you turn into Llangollen from Ruabon way coming in, its on the left hand side. Walk up the road, past the taxidermist and the canal tourist spot, then you can walk along the road past the car park, or go up the footpath past the school
