I have written about my dentist before who is a really cool guy. Not only is he a dentist, but he is also a practicing lawyer. More than that he is also a world traveller and an active global volunteer.

Dr. Arya recently did a treek through Nepal, which he described as his most challenging travel experience ever, physically and mentally. Read here about his adventure in Nepal:.

1) Please give us a general itinerary of the trip and a description of the trekk.Our trip was a 12-day trip in which we landed in the Delhi and eventually made our way by various modes of transportation to the State of Sikhim, which is in the very northern part of India. Sikhim is a very controversial state, as it is the subject of many territory disputes between China and India. However, I believe that China has just recently officially recognized it as a part of India.

The trekk involved first going to Darjeeling (yes, where the tea originates!), where we rested up and slightly acclimatized ourselves for 2 or 3 days in a very picturesque, tranquil setting. From there we took a 7 hour jeep ride up into Yuksom (Sikhim), a little village where trekkers usually start their journey. The long jeep ride itself was quite exciting as you are going up mountains on very narrow roads, and cars are coming from all over not paying particular attention to which side of the road they should be traveling. One side of the road has a sheer cliff with no guardrails, and you think you are going to fall down any moment.There were also some hilarious road signs going all the way up, reminding people to drive slowly: For example, "Don't hurry, so that you can enjoy your curry", or "Donate your blood at the blood bank, not on the highway." We really got a chuckle out of these signs.

Finally, after the long ride we made it to our starting point for the trekk where we stayed in a very basic hotel. It was probably a one-star hotel; however little did we know that this would actually be luxury compared to the accommodations that were still to come.On our trekk we had with us one sherpa guide, 2 sherpa cooks, and 2 sherpa horsemen for carrying supplies. The carrying animals are small ponies or yaks, since they are the only animals that can make it through the rough terrain.We started the trekk with daypacks- weighing less than 20 pounds.

We also carried water and fancy gear such as climbing poles, fancy hiking boots, etc. Members of 6 person group also carried medical and trekking kits. The heavier bags were put on the animals and taken up.

So, we were excited and ready to go.Basically, every day we walked about 20 km or so which took about 9 hours to do. We typically walked uphill for 8 or 9 hours straight with a one hour lunch break through various terrains. The vegetation changes the higher up you go.

We started at an altitude of about 2000 m where the vegetation was very green and lush. As we got to 4000 m (equivalent to the top of the European Alps) around the second or third day of the trekk, we started to see rhododendrons fade, less green and more shrubs. We spent about a day at that altitude to acclimatize ourselves.We stayed in wood huts or tents that had no electricity, no running water, no furniture, no plumbing, or no heat.

The nights got really cold, so the sherpas would boil water and fill it into our drinking bottles. We took those hot bottles and put them into our sleeping bags to keep warm. The next day we used the same water as drinking water. For the entire 8 days we did not really substantially change our clothes; we just changed socks in order to avoid blisters. You certainly don't want to expose skin too long in this environment.Interestingly enough, at about 4000 m I actually got a severe headache, my nose started bleeding, and my ears were ringing really bad.

Every night we would have debriefings: however that night I did not participate in the debriefing since I wasn't feeling well at all. I was very quiet. I took some diamoxx to help me more quickly adjust to the altitude.The next day I felt better, and we kept on going up. At about 4500 m we started to see snow and sleet. At about 5000 m we reached Samiti Lake, which is a high altitude lake.

It is very odd to see a little lake in the middle of these mountains. We camped out there, this was our pinnacle day. The next day we aimed to go to Lagochla which was going to be the high altitude point for the trekk. Of the 6 people in our group, 4 of us decided to make it to Lagochla. Last year 6 Germans actually died on this stretch because of an avalanche. They had been instructed by the sherpas not to go, but they went anyway- killing themselves and a poor porter.

To reach Lagochla we left at 2 am, when it was pitch dark outside. We had headlights on our heads and followed closely on the guide's footsteps. We were literally walking on the edge of cliffs at times. You don't know how far down the cliff is- it could be 2 feet or 200 feet.

All you can do is just concentrate and keep on walking. At 2:30 am, my hands started hurting because of the cold. Since it was so early into the trekk I did not want to say anything and embarrass myself. Right about that time, the girl in front of me stopped and started to complain about the same thing. We all stopped to evaluate the situation. She pulled out a heat pack to warm her hands.

I found that the act of moving fingers back and forth quickly actually calmed our fingers down. We continued to climb and at 4:45 am we reached our pinnacle. We didn't go any further than that. We had hit Lagochla I. Lagochla III was slightly ahead and was to be our planned destination; however the sherpas felt it was too dangerous to continue.

There was some heavy debate amongst them and then us. We decided we were done and would watch the sunrise from this point. Then we all did a little prayer with the sherpas. We savoured the view, which is, of course, unbelievably beautiful.

We were very close to Katchachamanga, the 3rd highest peak in the world. The view was truly spectacular. I made a mental note as we turned around at 5:10 am and I thought of my wife, saying to myself "I am coming home".

Little did I know that the walk back was extremely hard as well, it was very slippery and dangerous and very hard on the knees. At that point we were 4 days into the hard trekk and we had another 4 days to go.After our early morning trip to Lagochla, we got back to the camp at 8:30 am. We had breakfast and then we walked another 9 hours.

We slowly made our way down, 8 or 9 hours every day. On the second last day of the trekk, one group member got very violently ill. At one time she actually threw up 9 times an hour. She was completely zapped of energy. On the last day, another group member got sick. At this point, I decided to talk to the leader since I am familiar with this type of illness.

I figured both of them just needed rest, why don't I take them down as quickly as possible to the hotel. Coming down slower would be even more painful for these guys as they had the mental fortitude and physical tenacity to make a 'run' for it. We would aim for doing it in 6 hours instead of 9. So a decision was made that I would take them down. The 2 sick people and myself rushed down and we indeed made it in 6 hours.

Making it down safely was an incredible experience. I felt it was a real physical and mental feat.After rushing down from the mountains we arrived in the little dusty town where we had started and we felt like cowboys riding in.

The locals were sitting around in the heat watching three dusty travellers limp through their town with smiling faces. We were told that of all trekking groups that went up at this time, we were the only group that had made it to Lagochla, everybody else had turned around. We were very even more proud of the accomplishment.One of the sherpas said that Western people always say "we conquered the mountain".

Eastern people, on the other hand, say "the mountain let us pass". I am a firm believer of the latter. The rest of group came down a couple of hours later, exhilirated to make it back safely. We were all in a state of shock due to exertion, but we were happy as well.

3) Please comment on practical aspects of the trekk: accommodation, food, equipment, fitness level required.Obviously, one has to be in decent shape to do this sort of trek. I am not certain one needs to be a marathoner etc. do complete it. I was in good shape anyway as I run and work out quite a bit. From a cardio perspective, I did not feel exerted.

I did feel exerted tremendously from a muscular perspective as the duration of each trekking day was quite long. The trek can be hard on your knees and feet.We all had very high quality mountain boots and packs. We had breathable clothes and socks.

We would carry water bottles during the day along with high energy food stuffs like peanut brittle.As far as accommodation goes-well, what accommodation?.I would, however, recommend that if one elects to go on this type of journey then they be in good shape of course. Get your cardio to a point where you are not huffing and puffing after a 30 minute jog.

The mental training would be equally important. Read about the details of these types of trips and learn what to expect. Try to take some of the surprise out of it.

It may help.
