This road is a lot of fun, plenty of nice corners and beautiful scenery. Road surface is a bit patchy/gravely in places, but mostly fine. A couple of the corners do creep up on you and are sharper than expected, but generally great. Try adding the 6 miles from the A37 to Somerton down the B3153 If coming from Bristol direction, also a nice bit of road.
A charming B route that is well worth a small detour to take in. An excellent way of avoiding some of the more popular A roads.
