No, Mahavideh Kshetra cannot be physically reached from Bharat Kshetra in the ordinary sense.

In Jain cosmology:

• Bharat Kshetra and Mahavideh Kshetra are different parts of the middle world.
• They are separated by vast oceans and mountain ranges.
• So a person here cannot travel there by physical human means.

However:

• By great punya and right karmic conditions, a soul can be reborn in Mahavideh Kshetra.
• And in Mahavideh Kshetra, moksha is presently possible, because Tirthankars are active there.

So the correct Jain understanding is:

• Physical reaching: No
• Rebirth there through karma: Yes

If you mean moksha from Bharat Kshetra, then in the current avasarpini in Bharat Kshetra, moksha is not generally attainable now. In Mahavideh Kshetra, it is attainable through the guidance of present Tirthankars.
