Time out
Finding the local time zone…
Times are local to the spot (zone loading). The half-hour margin is our rule of thumb, not an official figure; light fades earlier in forest or under cloud. Carry a headlamp on any route that could run late.
Accessibility
- All three sites have short walks from parking areas; paths are uneven but manageable for most walkers.
Visiting lightly
- Support local accommodation (Toshali Ratnagiri Resort).
- Carry dry food; there are no restaurants on site.
