What to see in just about 2 half days in Guwahati

I am traveling to Guwahati for official purpose, but am likely to have Sunday (12th April) second half, and additionally Tuesday first half free.

I prefer outdoors/ natural beauty (hills, walking/ trekking trails etc) over buildings, museums & temples, although I am not averse to these, if there is nothing better to do.

Please suggest how to best utilize these two half days, keeping the above in mind.

Thanks

For the first time, no response to such a simple query !

I am sure Guwahati is not such a drab place. Come on IMers, please suggest some good places/ outdoors to see in or near Guwahati. Remember I may have only one half day !

Thanks
