Take an early economy/state/Volvo bus from Delhi (ISBT or major bus terminal) to reach Agra in the morning and maximize sightseeing time; buses typically take 3.5–4.5 hours depending on service and traffic.
Drop luggage and have a simple hotel breakfast (many budget hotels offer early breakfast or will provide a packed breakfast); this saves time and keeps costs low.
World-famous 17th-century mausoleum — visit for its architecture, gardens and photo opportunities. (Open sunrise–sunset; closed on Fridays for prayers.)
Eat at a popular mid-budget or good-value local restaurant near the Taj/Agra Fort to try local Mughlai dishes or simple North Indian thalis; restaurants open by 11:00–11:30 onward.
Historic red-sandstone fort with palaces, halls and commanding views of the Taj; great to understand Mughal history and architecture. (Open around 6:00am–6:00pm.)
Choose a well-reviewed local eatery or budget cafe (for example a community cafe/locals’ dhaba) for a safe, affordable dinner; many places in Agra are open until 9–10pm.
Have a quick breakfast at the hotel or grab a packed breakfast so you can leave early for Fatehpur Sikri and get the coolest part of the day for walking around.
Take a state-run bus or shared taxi toward Fatehpur Sikri (about 40–50 km, ~1–1.5 hrs). Buses are the cheapest option; shared taxis are faster but a bit costlier.
Explore the UNESCO-area complex founded by Emperor Akbar; Buland Darwaza (the grand gateway) is the highlight — the whole site shows Mughal planning and monuments. (Open sunrise–sunset.)
