Almost every journey on this coast comes down to one choice: the Marine Drive along the sea, or the inland highway through Chakaria and Ramu. The Marine Drive runs roughly 80 kilometres from Cox's Bāzār town south through Himchari, Inani, Ukhia and on towards Teknaf. It is narrow, winding and slow, with blind bends over hills between Himchari and Inani, but the views over the Bay of Bengal are the reason people come. The inland route is longer in distance but often faster in practice, especially in the monsoon, when Marine Drive sections can flood or wash out.
Allow three to four hours for Cox's Bāzār to Teknaf on the Marine Drive in a private car with photo stops, and two to two and a half hours on the inland road with no stops. Public buses cover Cox's Bāzār to Teknaf in around three hours when roads are dry. Leave Cox's Bāzār town before nine in the morning if you want to reach Teknaf with daylight to spare, and remember that no one should be driving this road after dark: unlit stretches, stray cattle and slow trucks make night travel genuinely unwise.
Local buses from Cox's Bāzār's central bus terminal to Teknaf are the cheapest option and run frequently through the morning; the fare sits in the low hundreds of taka. They stop often, fill up, and give you little control over photo stops. For the Inani and Himchari stretch, a CNG auto-rickshaw from Cox's Bāzār town is the practical choice for a half-day, negotiated as a return trip with waiting time rather than a one-way fare. Expect to bargain, and agree the total before you set off.
A rented car with driver is what I would book for a full Ukhia-to-Teknaf day. You get the Marine Drive both ways or a loop back via Ramu, stops at Himchari, Inani and the Teknaf waterfront, and no scrambling for the last bus. Hotels along Cox's Bāzār's Sugandha and Kolatoli beachfront can usually arrange one at a day rate, and the convenience is worth the premium when you are covering 150-plus kilometres in a single day. Motorcycles can be rented in Cox's Bāzār town, but the Marine Drive's bends and heavy truck traffic make that a choice for confident riders only.
Stay in Cox's Bāzār town rather than moving south. The Kolatoli and Sugandha beachfront strips have the widest range of hotels, from simple guesthouses to mid-range air-conditioned rooms, and everything from the bus terminal to the taxi stands is within a short ride. Inani, about 25 kilometres south, has a handful of quieter places near the beach and makes a reasonable one-night break, but as a base for day trips it leaves you dependent on whatever transport you arrived in. Book in Cox's Bāzār and day-trip south.
Skip the idea of combining Teknaf with a Saint Martin's Island crossing on the same day; the boat timings do not reward it, and you will spend the day in transit. Also skip trying to see Himchari, Inani and Teknaf properly in a single half-day. Himchari's hilltop viewpoint and waterfall are best in the morning light, Inani's long empty beach deserves two hours, and Teknaf's riverfront and the road towards Whykong need the afternoon. The best months for this coast are November to March, when the roads are dry and the sea is calm; avoid the June-to-September monsoon for long Marine Drive drives.
Fuel stations are concentrated in Cox's Bāzār town and at Ukhia; south of there, fill up before you go. Mobile signal is decent along the inland highway and patchy on parts of Marine Drive between Himchari and Inani. Cash matters: ATMs in Cox's Bāzār town are reliable, but between Ukhia and Teknaf do not count on finding a working machine, so draw what you need before leaving. There is a military checkpost at Ukhia and further checks closer to Teknaf, where you may be asked for identification, so carry your passport or national ID.
If you are heading to Teknaf purely for the river crossing views, the journey is the point rather than the destination. Teknaf town itself is a working river port, busy and utilitarian, with the Naf River separating Bangladesh from Myanmar. Most travellers find the Inani and Himchari stops more rewarding than time spent in Teknaf itself. Build the day around the drive, keep a buffer for the return, and be back in Cox's Bāzār before dusk.
