1. There are three variations to EBC: EBC via Gokyo Ri, Three Passes Trek and EBC. Out of these, EBC is easily a DIY trek.
2. There are Heli services to different villages on the EBC trail.
3. Bring your cash - You will spend a good amount on food and other necessity on the trek if you are not on a complete package tour, so carry some Nepali currency with you, as there are neither exchanges possible nor online transactions.
4. You can get an EverestLink WIFI card costing NPR 2500 for 10 GB of data.
5. Water is costly - Unlike many Himalayan treks, you don't get to fill your water bottles from the mountain streams here since they are not clean enough. So one should carry water purifying tablets if one uses the tap. You can also buy water (you also get a thermos flask) that's a bit pricy and, in some villages, that's the only option.
6. Temperatures even during the Spring season can drop to -10 degrees in the last village Gorakshep.
7. A pair of hiking poles can help you walk faster and work better in endurance and stamina.
8. Save yourself from Khumbu Cough! Keep your ears, nose and mouth covered while you sleep at night. Carry Strepsils. You will be surprised by its whooping price on the trek.
9. Accepting/Asking for tips is a custom well practised here.
10. Battery charging is on a paid basis. Price changes as you go deeper into the trek, like phone charging ranges from 200-500 NPR, while battery ranges from 500-700 NPR.
