After the early 7:00 AM bus from London, settle into Bath with a relaxed, self-guided start around the elegant Royal Crescent and the nearby The Circus, where you can admire the Georgian architecture without spending a penny. From there, wander down to the riverside for views of Pulteney Bridge and the River Avon, enjoying a budget-friendly morning that feels full of classic Bath charm before you stop for a simple coffee or snack.
In the afternoon, head to the Roman Baths area to enjoy the atmosphere outside the museum and then continue to Bath Abbey for a close look at its impressive Gothic frontage and peaceful square surroundings, all without needing to pay for entry. From there, keep costs low with a scenic stroll through Parade Gardens and along the riverside paths, making the most of Bath's elegant core before pausing for an affordable lunch or a snack from a local bakery or café.
As daylight softens, make your way up to the Bath Skyline for a free golden-hour walk that gives you sweeping views over the city and a peaceful end to the sightseeing part of the day. Afterward, head back into town for a low-cost dinner near Milsom Street or along Walcot Street, where you can find casual pubs, bakeries, or takeaway spots before settling in for the return 8:00 PM bus to London.
