Know Before You Go
This place is not well served by public transport. Hire a Suzuki van in Taxila to take you there and back. It's around 45 minutes from Taxila's main bus stop. If using your own car, use a short wheelbase vehicle with high ground clearance.
The guards on site are helpful and will assist with information, though the large printed signboard contains most of the information you will need.
While en route, be sure to stop to see the remnants of Afghan King, Sher Shah Suri's mid-16th-century cobblestoned sections of the Grand Trunk road. There's also a 40-foot tall stone obelisk erected by friends and admirers of Brigadier-General John Nicholson to view.
The best time to visit is between October and April. Bring a hat, sunblock, water, and snacks.
