I’m not fully sure which temples you mean, because:

• There are many Digambar and Shvetambar temples of Bhagwan Neminath (for example at Girnar, Ahmedabad, etc.).
• Directions will be different for each city / tirth.

To help you properly, please tell me:

1. The place / city / tirth you are in (e.g. Girnar, Ahmedabad, Khajuraho, etc.).
2. Are both temples in the same town, or are you travelling from one city to another?

Once you share this, I can guide you on how to go from the Digambar Neminath temple to the Shvetambar temple in that specific place (and also mention any Jain etiquette to follow while visiting).
