The rule: early, then rest, then late
| 05:30 to 10:00 | Outdoors: the boat ride, Mua Cave, cycling |
|---|---|
| 11:00 to 15:00 | Inside or in the water: lunch, pool, spa, a nap |
| After 16:00 | Out again: a short bike ride, Bich Dong, sunset at Mua Cave |
1. Take the first boat
The Tam Coc boats start around 07:00. At that hour the river is still cool and quiet. By 10:00 the sun is strong and there is almost no shade on the water.
2. Climb Mua Cave before 07:00 or at sunset
About 500 steps without shade. In summer, never at midday. Early morning gives you the view and the fresh air; sunset gives you the light but more people.
3. The midday plan
- A long lunch under a fan or in air conditioning.
- The pool. Many hotels in Tam Coc have one; some let day guests in.
- A massage. Two hours inside, cool and horizontal, is the best way to spend the hottest part of the day.
- A cooking class in the shade: private cooking class in Tam Coc.
4. Let the bike do the work
Cycling in 35 degrees is hard work. An e-bike gives you the wind without the sweat: rent an e-bike in Tam Coc, delivered to your hotel.
Stay safe in the heat
- Drink 2 to 3 litres on an active day. Oral rehydration salts help when you sweat a lot.
- Hat, sunscreen and a thin long-sleeved shirt.
- Headache, dizziness or nausea: stop, find shade, drink, cool down. Do not push on.
The upside of summer: late May to early June the rice turns golden along the Tam Coc river, and in June and July the lotus flowers bloom. Worth an early alarm.
