Caldicot is a small town nestled between the two Severn Bridges.
It sits on the B4245 between neighbouring Chepstow and the City of Newport.
As such accomodation in the town is limited so if you are using public transport you'll need to plan ahead.
Here is a list of some local accomodation you might want to consider.
Caldicot has two B&Bs.
The Lychgate B&B (click here for their website) has four twin rooms and is right next to the Castle Pub at the entrance to the Castle Grounds. The owner Janice is a family friend and the address is 47 Church Rd, Caldicot NP26 4HW.
Brooklands Motel has a twin a double and a 'family' room (with a double and a single bed) and is a couple of minutes walk from the Grounds. Call them on 01291 430500 (no website) - their address is Pill Row, Caldicot NP26 5JD.
The Coach and Horses pub is a 17th century coaching inn and has 3 rooms that provide B&B, and it serves food (oh, and ale of course). Really you'll need a car (or taxi) but you'll be staying within the walls of the ancient Roman City of Caerwent. It is walking distance of Caldicot if you're fit and bold but it is country lanes or cross country, so spend your XP on survival if that's your route of choice. Their website is here.
In and around Chepstow
Chepstow has a variety of accomodation and is a train, bus or taxi ride from Caldicot. Google your options and, as the Gnomes would say, 'take your pick'.
It also has a number of restaurants, and the Queens Head Micropub - one of a number of local award winning pubs.
Magor and Langstone
Again you'll have to consider transport, but there's the New Inn in Langstone, and Ty Hotel and a Days Inn in Magor (both the latter are next to the motorway junction)
If you have a car then there is a host of accomodation in Newport, from small B&Bs to the luxury of the Celtic Manor Resort. You could also stay near Newport Railway station if you wanted to hop on a train back and forth to Caldicot for the day. As Caldicot is a rural location trains are (roughly) hourly, but Rangers generally keep the route free of Kobolds save perhaps at closing time.
Camping at the Castle
As at 12.11.19 we have an enquiry out with the Castle Management about the possibility of camping in the grounds. The site is often used for camping, but we're not yet clear on what limitations there are with regard the time of year and so on. Watch this space for more details.
