Maybe a new tour

Welcome to the forum! You may or may not realize the folks on the forum are not RS employees. We are travel enthusiasts who may have taken RS tours or used his guidebooks.

Rick does not currently have a tour that includes the Channel Islands nor has there been one in the past.

I did a search (which I'm sure you've already done, lol) and none of the big US based companies tour there, nor does my small group company which is UK based. I'd suspect it revolves around the availability of lodging for a tour group plus reliable transportation to/between/from.

IF you find something I'd love for you to post! Jersey, Guernsey and Sark have always fascinated me!

There are cruises that visit the Channel Islands. We visited Guernsey.
The islands are interesting, since the Germans occupied them during WWII.
Also, the islands are the remnants of Normandy that was controlled by the English, but the French eventually pushed the English our of Normandy except for these islands.

One thing you might consider is taking a tour of other parts of England and then tacking on a trip to the Channel Islands on your own. I don't think it would be that difficult. You could easily get there from London by train and then ferry.

Here is one forum post that gives a lot of information about it: https://community.ricksteves.com/travel-forum/england/british-channel-islands

The Channel Islands aren't geared up to mass tourism. Roads are narrow and large tour buses would really struggle. ( I went on a group tour run by my local coach company. We were dropped off at the ferry terminal and the coach and driver didn't accompany us. We were met by a hotel tour representative when we arrived who gave us some information about the islands and what we could do. A day tour was organised using a local bus. We were met back by the coach off the ferry on our return.)

Picking up on Mardee's comment, bus services on both Jersey and Guernsey are excellent and it is very easy to get round the islands by yourself. I loved it and enjoyed the freedom of not beinjg organised all the time...

The main Channel Islands have local tour companies that will take you around to the major sights.

As has also been noted, bus services on the islands are excellent and can get you anywhere you need to go.

Traveling between island is also easy via either ferry or plane.

I visited a few years ago and will probably go back. I flew from London to Jersey, took a ferry to Guernsey and then flew up to Wales.
