Ashton is {{convert|18|mi|km}} from the southwest corner of Yellowstone National Park, {{convert|24|mi|km}} from Grand Teton National Park and {{convert|39|mi|km}} from the [[Grand Teton]] with a clear view. Ashton is surrounded by farmland but is less than five miles (8&nbsp;km) from the [[Targhee National Forest]]. There are four rivers within {{convert|10|mi|km}} of Ashton, and all are outstanding [[trout]] streams: the [[Henrys Fork (Snake River)|Henrys Fork]] of the [[Snake River]], [[Fall River (Henrys Fork tributary)|Fall River]], the [[Teton River (Idaho)|Teton River]] and Warm River. Also nearby are three notable waterfalls: Upper Mesa Falls and Lower Mesa Falls, both on the Henrys Fork, and Cave Falls on Fall River.

Ashton's climate is unique and distinct relative to most of the U.S. northern Intermountain West. Ashton's annual precipitation, at {{convert|20|in|cm|0}}, is among the highest in southern Idaho and yet Ashton is not in the mountains. Further, the areas five miles (8&nbsp;km) north or five miles (8&nbsp;km) east of Ashton receive over {{convert|30|in|cm|0}} of precipitation while [[St. Anthony, Idaho|St. Anthony]], only {{convert|13|mi}} to the southwest, receives only {{convert|14|in|cm}}. This unusually high precipitation in the Ashton area is due to the geography of southern Idaho and Yellowstone. The [[Snake River Plain]], formed by the Yellowstone hotspot across southern Idaho, creates a moisture channel that extends from the Pacific Ocean to the Ashton and Yellowstone area. Average monthly precipitation in Ashton shows a transitional regime. Precipitation peaks first in December–January, reflecting influence from Pacific Ocean-originating storms during the winter season, and second in May and June, reflecting showers and thunderstorms that create a May/June rainfall peak that prevails in nearby Montana and Wyoming. Ashton has relatively drier summers (July/August). This area marks the virtually easternmost extremity of the typical Pacific Northwest annual precipitation pattern, with its dry summers. According to the [[Köppen climate classification]], Ashton has a dry-summer [[humid continental climate]] ([[Köppen climate classification]]: ''Dsb'').
