The Short Answer
A private 3-hour tuk-tuk city tour in Colombo typically starts around $49-51 for one person, roughly doubling for a second traveller (around $85-102 for two) since most tuk-tuk operators charge close to per-seat rather than a flat vehicle rate. A private car day trip out of the city (Galle Fort, Negombo, Anuradhapura) often prices flat for 1-2 people — around $112-169 regardless of whether 1 or 2 travel — before stepping up for 3+. Multi-day private car tours around Sri Lanka (3-7 days, driver and hotels included) run roughly $900-2,000 for the group, a different, much bigger commitment than a single city day.
