Choosing
Both lie about four and a half hours by road from Bagdogra airport, and both are Buddhist Himalaya. They are not interchangeable: one gives you a living kingdom with its own rules, the other the mountain itself.

Bhutan
Dzongs still used as offices and monasteries, a licensed guide every day, a tshechu if your dates allow, and Taktsang at the end. Bhutan asks for 5 to 7 nights.

Sikkim
Kanchenjunga, 8,586 m (28,170 ft), from your room on a clear morning, most often October to December. Gangtok, the old royal capital at 1,650 m (5,410 ft), works as a base in three to four nights.

Cost
Our Bhutan journeys start at ₹3,25,000 per person for eight nights; seven nights through Darjeeling and Sikkim start at ₹1,40,000 (twin share, Bhutan's fee at the Indian rate). Certified hotels and a daily guide make most of the difference.

Sikkim's paperwork
On a US passport you need Sikkim's Restricted Area Permit, filed online about 30 days before you arrive, and for Tsomgo Lake a protected-area permit issued to groups of two or more. There is no nightly fee.

Bhutan's paperwork
A US$40 visa applied for online and reviewed in about five working days, a fee of US$100 a night until 31 August 2027, and a licensed Bhutanese guide throughout. If you fly, Paro lands aircraft only in daylight and good visibility.

Who suits which
Choose Bhutan if ritual, architecture and walking up to monasteries are why you travel, and you have a week. Choose Sikkim if Kanchenjunga matters most, time is short, or a guide beside you every day would feel like a constraint.

Planning
Sikkim and Bhutan share a border but no crossing, so the road from Gangtok to the Bhutan gate runs back through West Bengal: one long day of about seven hours. Our Two Kingdoms journey joins them in 11 nights.
