As above, Whitemead is a holiday place just out of Parkend and clear access to the woods and trails around that area.
Deanwood Holiday Cottages is up by pillowell and has good access to the woods and trails in that area, and central for others.
Loads of AirBnB’s around, pot luck really.
We go and stay for a few days every year, we’re only 30 minutes away in the car over the bridge, but my daughter doesn’t travel well, so we kind of make it a holiday almost from home, stayed in some nice enough places, last year it was Pathwell Farm, nice and clean, next to Bream, animals and so on for her, but was a car ride to do stuff, except me on the bike, that was easy offroad.
Reality is, you probably want to plan the week out, so much to do with the family that if you plan, you’ll have a clue about what you could get away with for a cottage, we tend to go to the Taurus centre for my girl doing craft stuff, Clearwell Caves, Puzzlewood, etc for the usual attractions, and the likes of Beechenhurst for biking and the go ape stuff.
cottages.com has a few up in the area, always worth a look, this year we’re up in Symonds Yat, although we may switch back to Pathwell, as my girl has a crush on the dogs (boxers!) that are on the farm!
