Malaysia's green Cameron Highlands are one of the few places in Southeast Asia where you'll want a jacket -- particularly at night -- but after sweating across tropical climates, you may appreciate the change. You'll have plenty of lush scenery, beautiful tea plantations to tour, and access to decent trekking trails that weave through plantations and around volcanoes.
Strawberry farms, butterfly gardens, and flower greenhouses are all enjoyable distractions in the Cameron Highlands.
