I *think* it is a Jungle-hex, so Jungle entry cost (only). However bypass would be impossible due to the Bamboo.
You could argue that in this particular case of G2, the Jungle portion does not "dominate" the hex, i.e. that the Bamboo portion is more than marginal. In that case, the terrain effects of Bamboo and Woods would be cumulative, which would mean the hex would only be enterable by Minimum Move in the MPh from F1.
"B.1 SYMBOLOGY: For aesthetic purposes, terrain symbology may extend marginally out of a hex into an adjacent hex of another type, but most hexes are dominated by one specific terrain type and are governed by the rules for that specific terrain type. Usually, the dominant terrain type includes the hex center dot, but occasionally building hexes have a hex center dot in Open Ground; an Open Ground hex center dot never changes a hex containing a building to an Open Ground hex. In some cases a hex will contain more than one terrain type with neither dominant over the other, in which case the terrain effect of both types are cumulative."
