The Golden Triangle in India typically refers to Delhi → Agra → Jaipur. These are three iconic cities with rich history, forts, palaces, culture & heritage. Wikipedia+2goldentriangletourindia.com+2
Adding Udaipur gives you a beautiful lakeside/romantic dimension, more of the Rajasthani culture, palaces, scenic views. Many tour operators offer “Golden Triangle + Udaipur” extensions.
Night / Evening Activities in Udaipur
To make the most of night/day in Udaipur:
Guided night walk to see the city illuminated, lakeside promenades. travjoy.com+1
Evening boat ride on Lake Pichola to see palaces lit up.
Dinner at rooftop lakeside restaurants.
Sunset point visit (e.g. at Monsoon Palace or from viewpoints).
Exploring ghats (Ambrai Ghat, Gangaur Ghat) after dark.
Things to Consider / Choices
Travel mode: Road vs flights vs trains. Delhi-to-Agra, Agra-Jaipur are well connected by road and train. Jaipur-Udaipur is quite long by road (~6-7 hrs), so either a good road journey or a short flight helps if time is limited.
Pace: You can compress/trade off days depending on how much time you want in Udaipur vs Golden Triangle. If Udaipur is very important, maybe extend 1-2 days.
Accommodation: Stay in heritage hotels in Udaipur for the vibe; in Delhi/Jaipur maybe heritage or boutique hotels depending on budget.
Season: Best time is October to March when weather is pleasant. Avoid peak summer (April-June) or monsoon (July-August) for Udaipur.
