Phunki Tenga beside the Dudh Koshi River is a good spot for Himalayan Griffons
which nest in cliffs further up along the Dudh Koshi. It is also a good two
hours climb up to Tengboche from here so it makes sense to fill up and/or get
some refreshments. Just past the bridge built by Peace Corps volunteers, there
is an Army checkpoint. Look out for pheasants and musk deer during the steep
climb to Tengboche.
If you aren't feeling too well because of the altitude, you should perhaps
consider sleeping it off here, as Phungi Tenga is as low as it gets past
