Hi CaliMom,
We used Bath as a base camp for 2 weeks last year and we were reluctant to leave, having felt there was much more to experience in the region. We rented a beautiful apartment with the Royal Crescent at our front door and Royal Victoria Park at our back. It turned out to cost about $94 per night with the per week discount. Our goal was to live like locals, go to the local grocery store, take public transportation or hire a car/driver, and take our time exploring. For example, we spent one whole day in Lacock, strolling through the Abbey and the grounds, studying the items in the Fox Talbot museum, wandering around the little town, and taking a hike on one of the trails near the village. Apart from the big tourist sites such as Bath Abbey, the Pulteney Bridge, and the Roman Baths, Bath and the surrounding towns have lots more to offer as far as countryside walks, biking opportunities, beautiful gardens, beautiful villages, churches, and pubs, and stately, historic homes with acres of gardens to explore, etc. The railway station will get you to numerous day trip destinations within an hour to hour and a half - Salisbury, Cardiff, etc. We used Russells of Bath taxis for a drop off and pick up in places not as accessible by bus or train. For example, we were dropped off in Tetbury and enjoyed exploring the church and village. Don't miss the award winning, "Britain's Most Beautiful" toilet near the visitor's center, ha, ha. We then had a very beautiful country walk from the town to Chavenage House, where Poldark was filmed. That was one full day for the village, lunch, Chavenage tour led by a family member, and then tea in their ballroom. Highly recommended is the Kennet and Avon Canal. We walked it, we biked it, and we did a cruise on The Lady Lena, a beautiful old wooden Victorian era electric narrowboat. One of the loveliest, traffic free bike rides I've ever done was from Bath to Bradford on Avon and back along the Kennet and Avon. If you are the type of traveler who likes to slow down, walk, and soak in the local culture, Bath has more than enough to do. On rainy days, there are museums, pubs, and the Theater Royal Bath. We saw the wonderful Jonathan Pryce in "The Height of the Storm" before it hit London and now Broadway. Now for the negatives....Tourists and students. The tourists, hordes of them, seem to be near the Roman Baths, the Abbey, Parade Grounds, Pulteney Bridge, and connecting streets. Once away from there, you can avoid most of them. Try to visit the big sites early in the morning and you'll be fine. At the end of September, school starts and the University of Bath students come pouring in. The local grocery stores were wall to wall students, for example. The local population seemed to double. More traffic, more people, more noise... It's a good time to get the hell out of there - unless you like that "city vibe", of course. Last thing: we've read up on Chester and that looks like a great base as well, as one poster recommended. We hope to check it out one of these days. Best of luck to you.
