Lopburi town is split into old and new quarters. The old quarter sprawls out from the train station and is completely overrun by monkeys, while the new quarter lies a few kilometres to the east and is centred around a massive roundabout, near the bus station.

The main sights are all within walking distance of Lopburi train station. The one outlying site is Wat Phra Phutthabat which, while actually in Saraburi province, is usually visited from Lopburi. Few travellers stray further afield in Lopburi. You can actually cover the highlights within just a few hours.
