If you are thinking of hiking up to Pico Bolivar, make sure you consult with a tour company and see about taking a guide. It is a very difficult hike from the bottom to the top and the terrain changes considerably from being in a lush, warm forest to snow covered terrain. And with this, of course, the oxygen in the air changes considerably and can heavily affect some people as they climb higher.
I have heard of many people getting lost and dying on the mountain so be very careful. Make sure you consult with a tour company first on where you should and should not go, what you need to take, what types of communication you will need, etc.
There are many tour companies in Merida you can pop in to, but i recommend Arassari Trek. They were super helpful and friendly - www.arassari.com
Unfortuantely we didnt know this and got to Merida only to find despite it being peak season, the teleferico (cable car) was under a maintenance and not working for 5 days. Tickets were then sold out for 3 following days.
Tickets always have to be reserved in advance apparently.
Have a look on website or call before going.
White low clouds, white thick fog - it was a daily sight in july 2004. We've had it every single day - often ruining our hiking plans.
My advice is that if you really want to see some place over 3000 metres, you should leave very early in the morning - and manage to arrive at your destination at 8 o'clock. Why? Because at 9 o'clock the sky often starts to cloud, and at 10 o'clock everything will be wrapped in fog. End of sightseeing - end of seeing! Or else... I might have been just very unlucky! Twice we went to the Laguna Mucubaji, twice we saw very little (see photo). And as for the famous Teleferico... just forget it! Too foggy!
