I quite like the A30 from Salisbury to Shaftesbury and then the A350 will take you to Blandford where you can pick up the A354, just before you come into Shaftesbury you can go to Compton Abbas and they have an airfield there where you can get a cup of tea and some cake. Also you take a short detour up the "Zig Zag" from there, you want the B3081 to Cann Common have a look at the google map, it should be obvious where the Zig Zag is...

A35 to Lyme isnt a very exciting road, you'd be better off going down into Weymouth and then getting on the B3157 which takes you through Abbotsbury & Burton Bradstock into Bridport and then go to Lyme Regis or West Bay from there.

The B3157 follows the coast much more closely and the views are stunning, where as the A35 isnt as twisty or as much fun and has bits of Dual Carriageway in it.

Your route back from Lynton / Lynmouth will take you along the A39 which is OK if theres no traffic on it, if its busy its horrible, it has lots of double white line sections and if the traffic is heavy it can be challenging to make progress, which is OK if you like that sort of riding but I just get fedup with it.
