Java Lava

Java Lava is an informal group of individuals who enjoy trekking, and invites others to join their trips. Java Lava is not a membership organization. Since its inception, Java Lava has been nothing more than a mailing list.

General Inquiries: Nicholas Hughes,
Trips are announced on a case-by-case basis. Registration: Trip Leader or Jenny Dewijani,
