Gros Peak is a dominant peak in the Gros Ventre Range. It's hidden from down in Jackson Hole, but stands out when viewed from any higher ground that affords views of the Gros Ventre range. It guards the headwaters of Granite Creek and is the peak people gaze at from Turquoise Lake. The view from its summit is breathtaking given its position between the Teton Range and the Wind River Range. On most days one can view the Grand Teton and the peaks surrounding Titcomb Basin in the Wind Rivers, plus the peaks of the Gros Ventres, Wyoming Range, Salt River Range, and the southern Absaroka Range.
The most popular trailheads to access the peak are Cache Creek TH (by either following the trail through the Flat Creek headwaters en route to Turquoise Lake or getting on the Highline Trail to access the peak's south faces), the Goodwin Lake TH (follow the trail past Goodwin Lake and join the previous route in the Flat Creek headwaters), or the longer route from the Grantie Creek TH. The Cache Creek TH is accessed from the town of Jackson, the Goodwin Lake TH is accessed via the Curtis Canyon rd, and the Granite Creek TH is accessed from the Granite Creek rd in the Hoback Canyon.
No real red tape issues except the normal lightning hazards associated with climbing peaks in the summer. It should be noted that Gros Peak has fairly stable rock when compared to other Gros Ventre peaks outside of this line of peaks running from Gros to Jackson Pk's, although some loose rock could be encountered.
Great camping spots can be found around the Turquoise Lake. Another nice alternative to this somewhat popular area is to camp in the upper Little Granite Creek headwaters area if accessing the peak from along the Highline Trail, but beware that some cattle may be encountered.
