Sector 66 lies along Airport Road/NH-5 in Mohali, next to Phase 10 and Sector 67, with Guru Nanak Road and Mohali Railway Station Road linking it to the rest of the Tricity. SAS Nagar/Mohali Railway Station is about 2 km away, and Chandigarh International (Shaheed Bhagat Singh) Airport is roughly 11 km via Airport Road.

CTU city buses connect the area to Chandigarh's ISBT-43 and PGI. The Tricity currently has no metro; a DMRC-prepared rail-corridor proposal remains at the planning stage.

Ryan International School and AKSIPS operate within/around Sector 66, with Doon International School about 1.8 km away in a neighbouring sector.

For higher education, Mohali's Knowledge City (Sector 81) - home to IISER Mohali and the Indian School of Business - lies a few kilometres away, giving Sector 66 residents reasonable access to the city's premier institutes alongside local schooling options.

Sector 66 anchors part of Mohali's IT/ITES landscape: the 13-acre Bestech Business Tower hosts IT, BPO and corporate offices, while GMADA's officially notified 'IT City, Sector-66 Beta' layout earmarks commercial and industrial plots within the same numbered sector.

Mohali has been recognised as one of India's fast-emerging IT hubs, with software services, BPO and telecom firms operating across the city's IT parks.

Sector 66 is primarily residential-commercial rather than a tourist draw, but it sits within Mohali/Chandigarh's broader sightseeing circuit: the historic Gurudwara Amb Sahib (Sector 62) and the Punjab Cricket Association Stadium, which hosts international cricket and IPL matches, are both within the city, with Chandigarh's Rock Garden and Sukhna Lake a short drive away via Airport Road.

The sector's own Bestech Square Mall (3.5 lakh sq ft) has a 5-screen Cinepolis multiplex, a Reliance Smart hypermarket, Reliance Trends/Digital/Jewels outlets and a food court with brands such as KFC and Pizza Hut, alongside 100+ other retail stores.

Chandigarh's larger Elante Mall is a short drive away, giving residents both neighbourhood-level and city-scale entertainment and retail options.

Developed under GMADA's sector-grid town plan, Sector 66 mixes apartment towers, plotted housing and the Bestech commercial complex along wide arterial roads. Part of the sector falls under GMADA's officially notified 'IT City, Sector-66 Beta' scheme, whose layout has recently seen government-invited public objections/amendments.

Local hospitals, banks, ATMs and petrol pumps are rated easy to access by residents, though some Beta-scheme pockets remain under active development.
