As the name suggests, this is a 'jewel' among the forests in the region.
It is an interesting fortress, situated at the edge of the ghats with numerous
water cisterns and caves. It also commands an excellent view alla round, overlooking
the Konkan plains, Bhandardhara lake, Alang, Kulang and the huge wall of Ajoba. From
Bhandardhara lake, walk across the dam to Mutkhel. Usually a boat is available here
to ferry across an arm of the lake to Ratan wadi. A steady uphill climb of about 4 hours
leads to the top. One has to negotiate a small chimney to enter the fort. A thumb-like
pinnacle(Khunta of Ratangad) facing Alang at 1230m is an interesting proposition. After
the descent from the fort, one can proceed to Kathra and Ajoba or on the other return
to Ghatghar or Samrad villages. From here a route leads back to Bhandardhara via
Udhavne(30km) or one can descend to the Kokan plains via Karoli ghat to Sakurdi
village(13km) for a bus.
