Travel definitely, but also explore your hobbies. Always wanted to hike the pacific crest trail? Go do it. Always wanted to make handcrafted musical instruments? Go find an apprenticeship. Think taking a class on woodblock printing sounds interesting? Do it. As someone married with three kids and on the cusp of 40 who never took that moment to explore anything outside work, I'd strongly encourage you to go explore those hobbies and creative interests - you might find you don't want to come back to development.
