What to visit between south London and Minehead

[questionsneverstop]

It says it all.
We need to go to Minehead in August and we are looking for a nice place where to stop on the way there.

Could you give me ideas please?

Coate Water Country Park is just 3 minutes from junction 15 of the M4. It’s a great alternative to a motorway services stop as it has loads of facilities for children including a play area and pitch & putt! There’s a gentle walk on level surfaces around the lake – perfect before heading back to the traffic of the M4. There are also plenty of other more adventurous and longer routes, with information available at the office in the car park.

Lydiard House and Park is just a few minutes from junction 16. It’s geared up for children, with a play area, children’s quiz trail through the walled garden and plenty of room to roam. You can even hire a bbq!

Dyrham Park is a National Trust house and parkland very close to junction 18. There are formal gardens and a lovely deer park to roam. Cream teas are served at the tea rooms and there is also a good gift shop.

Thank you so much, Ricekrispie22.... I was actually thinking of a place where to stop overnight, somewhere to visit...so even a bit further than the motorway.
